Now you're exaggerating. We have an (oldish) Brother "laser" networked
printer which was quite affordable and understands pretty well PS (well,
officially it's "brotherscript" -- really!) but it works nicely either
from the whole CUPS gorilla or from a more traditional lprng installation.

No blobs, no frills. Only this stupid 99.9% compatible PS ripoff is
sometimes annoying, I guess if they'd left the (official or inofficial)
copy of Ghostscript just alone instead of tweaking it, it'd be better.

It is, fwiw a Brother HL 5170DN. Would I recommend it? Well, the
mechanical quality is what you'd expect for the price. It tends to
"decorate" its first pages with some creases. It is very low on
mem, and its RIP isn't really fast. But it has done its job for
well over seven years now.

So. Now I'll bite off my tongue and take my ball with me. I'm off
this thread. I can't bear the overall animosity and poking of
fun at those who try to put some effort into avoiding binary
blobs. It reminds me of the poking at vegetarians "now are snails
vegetables or not?". I thought I left that behind in my teens.

no, not for me.

there are two parts: having a hardware that just works, and for this 
Brother is better than many other makes, and getting free of privative 
software, which is better but harder.


By the way it's a bit of a dead way: even RMS do not ask for free 
BIOS... when he could (there is work on the subject).


I remember the time where every printer was sold with a manual stating 
what codes was giving what.


So working toward a free driver is a good idea, but this have to be done 
with knowledgeable people, probably (no offense!) not to be found here 
but in gutenprint mailing list

No. (I think you meant PDF).

The PDL of choice for AirPrint capable devices is PDF. A PDF document
sent to an Airprint capable printer is converted to BUL (the Brother
Unknown Language) as it would be if it was processed on a workstation by
CUPS.

Note that this is a conversion, not an interpretation. An interpreter
produces a raster image and this happens later when the RIP deals with
BUL.

The important word is "direct". The MFC-J5720DW doesn't have a  PDF
interpreter. Hence the silence.

After a routine upgrade (which did *not* raise a changelog notice), any

being left to fix them. I'd say that was a bug.

you might have some network manager running - at least in my case. I solved
all similar issue by disabling all setup in interfaces and using the

IIUC, not any more if you have dhcpcd5 (the only version available in
the current stable Jessie). It is an autonomous daemon which detects
when an interface is up and tries to configure it, unless configured
otherwise.

Re: Android emulator

[Rastko]

Eclipse on Windows was something of a usable disaster, which I
can't say for Android Studio, which is both a disk, CPU and memory hog.

It apparently needs a lot of config to work.

As far as emulator goes, I had to ditch the official emulator (rebranded
QEMU), simply because I don't have hardware virtualization functions on
my processor. I've decided to use Android-x86-eeepc on VirtualBox, but
this will only work up to version 4.0 or something, later ones require
VT-x as the official emulator does.

You can install the eeepc image on virtual disk, so you can have
writable file system; you can push files via remote shell, setup SL4A
scripting engine, use Bridged Networking for LANning to it, and many
other stuff (Debugging is a given). It's MUCH faster (I guess cutdown)
then the official emulator+images, can't seem to figure out why... It
probably lacks something, but for developer work does the job.

I tried recently official emulator+images on a VT-x machine with HAXM,
it IS faster, but hickups every now and then. And I must say, it is a
tad slower than the unofficial x86+VirtualBox... or so it seems.

No I am not. We (the tv station where I spent my last 18 working year at 
as the Chief Engineer) needed another copier/printer about 15 years back 
as we were overwhelming the $17,000 model, people standing around 
waiting their turn, and the local office supply business sold us a 
Minolta that could, if you fed it the right supplies, even bind a book 
for you, and yes it was $35k at the time, plus of course an annual 
maintenance contract that was for same day service. It had everything 
but a coffee spigot on it.

Much the same can be said for the HL3170CDW I have, its an entry level 
color laser.  Beginning to have some smudge and streak troubles, but it 
has nearly 4000 pages thru it. And I just found it needs a full, pull 
the line cord out, powerdown reset to restore normal operation, a panel 
switch reboot doesn't cut it.  It also needs a firmware update, but they 
have about 5 of them, each customised for the windows machine it takes 
to run the updater.  But to find a winderz machine to run the updater 
isn't possible here as there aren't any here. 100% linux here. I've not 
tried our dfu utilities to see if that could work, and I'm not sure I 
could strip out the actual update from their windows packages.

It has been said in this thread that "Printers are dark and muddy";
there is no need to muddy their operation further, as is done here.

With a CUPS installation the brother_lpdwrapper_mfcj5720dw filter
converts PDF into BUL and sends the data to a RIP (an interpreter)
on the printer. AirPrint uses exactly the same printer as CUPS but
the conversion done by brother_lpdwrapper_mfcj5720dw has to be on
the printer in firmware. Then the RIP takes over. The RIP is not
converting PDF to raster format. There is no PDF interpreter for
AirPrint to use.

> http://www.linux-magazine.com/Online/Features/AirPrint

Listing 2 on that page isn't needed with Debian CUPS.

And I left time wasting in my teens.

It is not clear why OP would not install the vendor deb files. If s/he wants
to gain security, he could do it in a different way and still use the
printer. Example old Raspberry costs ~30-40$ and voila you have your
dedicated printer with no network.

Never mind - I wish him/her luck and perhaps s/he will update us later on
the progress and findings.

IMO it is not likely that one adds a spy software on such low cost device -
what for? If you want to print confidentail information - there are other
types of printers and setups you could do so.

Doing some more usable things, could be more beneficial to him/her. Anyway
this is a personal choice, but the effort seems silly, so we (I think I am
not the only one) have spoken and warned him/her.

Well, it doesn't need to have it's own /spyware/  it might be badly
setup and perhaps be taken over by something smarter.  This whole IoT is
very dangerous -- talk of putting them all on their own network is not
enough as each can attack each other and any of them can try to
compromise the /other/ network via jumping on to the network it is not
supposed to know about.

And yes, that might be extreme, but people are too trusting of junk that
is polluting this world just to make another dollar quickly; junk that
isn't secure to start with and too cheap to ever consider that to change.

AirPrint supports PDF, JPEG and URF as PDLs. URF is obligatory. PDF is
the PDL of choice if the device supports it.

So, you do not *have* to send PDF to Airprint but is very common for
that to happen.

How to install Perl with readline support?

[Kynn Jones]

Hi everyone,

I have been searching for the answer to the subject line's question
for the last two hours.

None of the answers I've found work.  (I.e. the `perl -de 1` REPL
remains without readline support.)

I have already `apt-get install`-ed

libreadline-dev
libterm-readline-gnu-perl
libterm-readline-perl-perl

(...along with their dependencies, of course).  I also ran `apt-get
install --reinstall perl`, and `dpkg-reconfigure`'d everything in
sight.  All of this got me nothing.

I'm puzzled by how difficult this problem has turned out to be.
Usually, `apt-cache search ...` followed by `apt-get install` takes
care of stuff like this.  In the harder cases, the first hit from a
Google search has the answer.  What makes this one so difficult?  Am I
missing something?

TIA!

I have to say that I usually just install perl modules from CPAN. It's too hard 
for me to match up the module that the perl error is complaining about with the 
correct debian package.

Just a hunch but maybe you booted the wrong kernel, or the initrd for
some reason wasn't regenerated after the firmware was installed?

On my Wheezy 7.9 box, Term::ReadLine is already installed.


RTFM Term::ReadLine, pasting the SYNOPSIS into a script, and running it:

$ cat readline.pl
use Term::ReadLine;
my $term = Term::ReadLine->new('Simple Perl calc');
my $prompt = "Enter your arithmetic expression: ";
my $OUT = $term->OUT || \*STDOUT;
while ( defined ($_ = $term->readline($prompt)) ) {
my $res = eval($_);
warn $@ if $@;
print $OUT $res, "\n" unless $@;
$term->addhistory($_) if /\S/;
}

$ perl readline.pl
Enter your arithmetic expression: 1+1
2
Enter your arithmetic expression: ^[[A^C


History did not work on the second prompt.

RTFM Term::ReadLine indicates that a back end is needed. Either of the 
latter two you installed should be sufficient.



If I install:

libterm-readline-perl-perl


And run the example again:

$ perl readline.pl

Enter your arithmetic expression: 1+1
2

Enter your arithmetic expression: 1+1
2

Enter your arithmetic expression:


History works, but there are extra blank lines between prompts and my 
terminal can get stuck in bold mode depending on how I exit (?).

Don't you think there has been a very positive aspect to this thread?
Not just for Jarle Aase's immediate needs but also for present and
future readers of it.

Misconceptions have been cleared up, the OP knows now why he couldn't
print and various byways have been explored. Even the binary blob issue
was treated with robust respect. Of course, people are entitled to
persue freeness and Jarl Aase did explain his position and had it
acknowledged. Others couldn't quite accept why someone should want to
turn down an easy route to printing with proprietary software. That's
all part of life's rich pattern.

Printing was, of course, the objective. There is a solution on the table
which fits the desire for freeness. Jarl Aase appears to be the only
participant in this thread who has access to an AirPrint printer.
Considering the interest which has been shown in his problem  some
feedback would be useful to have. I hope we haven't lost another ball. :)

I've been in that box, watching them tie knots on ropes too.  But at the 
end of the day, I only outlaw one driver blob, the nvidia. It locks out 
the IRQ's for extended periods of time and can, because of that, do 
serious damage to parts being CNC machined.  The nouveau driver doesn't 
resort to that, and works fine, for what I want to do.  So for me, the 
nvidia driver and its being married to a specific kernel, causes way 
more problems than it solves.

Thanks.

What happens when you run

My Brother HL3170CDW has a wireless interface, but no clue as to its 
usability with airprint, mainly because I have it disabled in its own 
menu's and have not explored that route to moving data.

And yes, my router with a DD-WRT reflash CAN do WLAN, but enabling that 
gives the whole world driveby access to my home 4 or 5 machine network 
unless I setup a different network just for the printer. So I have, 
having been attacked via that path, for security reasons, disabled ALL 
the WLAN style wireless.  Cat5E all over the place though.

One piece, swinging in the wind between the house and a small shop 
building nominally 40 feet away with 2 or 3 computers running smallish 
CNC controlled machines in it, and has been swinging in the wind for a 
decade & change now, still works fine right now.  And I've no clue why, 
it stood up to a measured 112mph wind in 2010 that cost me 4 trees and 
most of my fencing and part of the roof, siding and gutters of this 
house.  But the cat5 survived.

Debian is not about freedom of choice. Can this be seen in the Social

I wouldn't exactly call it a bug. Adwaita is the default GTK+ theme in
GNOME and it doesn't seem to be found on your system, 

You could try to install gnome-themes-standard and see if that changes
it, or try another theme.

The existence of a wireless interface on a printer has no bearing on
whether it supports AirPrint. Many printers have wireless interfaces
and do not support AirPrint.

In addition, an AirPrint printer does not need wireless capability on
it; it is not a requirement. The only requirement is for the printer
to broadcast mDNS.

You can see what your printer does by using the novel idea of looking
at its manual. Guess what? :)

You are the only person in this thread to own up to having an AirPrint
Brother printer. That places you in an ideal position to test the ideas

I didn't claim AirPrint, only that it could have a wlan connection IF it

I'm still on wheezy, but that output is likely north of 200k.  It finds 
an ipv6 address for a lot of stuff here, but ipv6 is disabled. Or is in 
the configs I use.

Probably 2 dozen stanza's of stuff on this printer, another dozen or so 
on a $110 B&W laser in the basement, and at least that many for an Epson 
NX515 whose printer died from clogged nozzles less than a month after I 
bought it, but its scanner works well. How avahi found it when its not 
even turned on is beyond me unless turning it off is not a full 
powerdown, or the USB cable is powering its interface.  Not to mention 
at least 50 other devices each a separate listing according to the 
protocol avahi queries I guess.  Way too big to post to a mailing list 
w/o an hours editing to trim it down to just this one printer. All the 
printers are shared to 4 other machines, and avahi finds it connected to 
them all, with every protocol in its basket. So I'm not going to inflict 
the list with that much trash data.

events for power plug

[Bruno Schneider]

I have a notebook with Debian testing (Stretch) that gets slow
whenever the power cord is plugged in. I can't figure out the exact
reason for that, but it seems that setting the CPU governor to
performance helps a lot.

But calling cpufreq-selector is hard for regular users. I wish to make
a script that is called upon power plug events, with root privileges.

I read documentation from acpi and pm-powersave, and from my
understanding, scripts in /etc/pm/power.d/ should be called every time
the power plug status changes with parameters "true" or "false". So I
created a script there, but it seems to be called only at boot time,
and not every time the power plug status changes.

Can anybody help?

Specifications for your printer are not avaialable online? Brother do
not tell you what the printer does? if you cannot be bothered to look,
why should I. Is there an unbelieving emoticon?

Need help salvaging what I can from major disaster

[Kynn Jones]

The plan was:

  1. back up my hard drive to a new external drive;
  2. reinstall Debian;
  3. restore my data from the external drive;

I did 1 and 2, but when I went to restore data from the backup, there
was nothing there (except for a lost+found).

I don't understand how this could have happened.  I've done this sort
of thing many times, and this has never happened before.  (Needless to
say, I'm ready to shoot myself.)

Now my most pressing need is to salvage whatever I can from the hard disk.

Any advice/recommendations would be much appreciated.

The cpufreqd package already does this.

Install, and look at /etc/cpufreqd.conf

Or,  you could poll the command on_ac_power to get the
status changes.

Re: Need help salvaging what I can from major disaster

[Kynn Jones]

I realize that my last e-mail included too little information.  Sorry
about that.  Here are some more relevant details.

It turns out that I backed up the hard disk (HD) to the external drive
(XD) twice.  The first backup went well, as far as I can tell.  I
spot-checked individual files, etc.  Everything looked normal.

This first backup would have sufficed, but after I had done it I came
across the recommendation that a disk of that size (2TB) should be
formatted for ext4, whereas I had originally formatted it for ext2.  I
reformatted the disk for ext4 (fdisk + mkfs.ext4), and then repeated
the backup.  This backup procedure was in the form of a shell script,
that I had tested repeatedly.  I just re-ran it.  My memory is fuzzy
on the subsequent details.  Since everything had gone so well up to
that point, I probably did not check everything as obsessively as I
had up to that point, but something must have gone very wrong.

At any rate, at the moment, my only hopes are that

  1. something may be recoverable from the first backup in XD;
  2. something may be recoverable from HD.

The second of these is (I think) less likely, because I changed the
partition scheme for HD, going from a single partition, to separate
partitions for /, /var, /tmp, and swap.  In contrast, XD has always
consisted of a single partition.

Now I'm looking for some data recovery tool (preferably from Debian)
that either is part of some bootable media, or that I can use from a
USB stick after first booting from a Debian Live CD.

Any recommendations for these would be appreciated.

Many thanks in advance!

Tails -- wheezy based good, jessie based bad

[Andrew McGlashan]

Hi,

Just reporting that I have a couple of older machines that both work
well with Tails 1.8.2 -- an old Thinkpad that used to run XP and an old
Macbook Pro 4,1 (early 2008).

Tails 1.8.2 is based on Wheezy.

Both machines fail on Tails 2.x -- the Thinkpad gets further than the
Macbook Pro.  2.x is based on Jessie.

Don't know why they don't work with Jessie / systemd setup, but one
would have thought that Tails should be made to work on just about any
machine.

Tails 2.x works fine on a much newer laptop (18 month old one with
i7-4700MQ cpu and nvidia graphic card -- on the whole anyway; there are
glitches getting to the "applications" menu; it works for a bit, then
stops working unless I open the places menu and move left to the
applications menu.  Strange.

Anyway, just thought I would put it out there.  Have "whispered" back to
Tails team on these, so hopefully fixes will be forthcoming in time.

Cheers
A.

Re: Need help salvaging what I can from major disaster

[Kynn Jones]

OK, post-mortem:

  1. after reviewing everything, the best hypothesis I have is that
the root of the problem was a bug in my backup script: it should have
checked that the backup disk was properly mounted before proceeding
with the back-up; something may have gone wrong with the mounting of
XD after it was reformatted, but this failure went undetected; rsync
just created the target directory under /media in HD.

  2. it looks like photorec can find a fair bit of recoverable data
from the first XD backup, but it's going to be a long slog to sort out
the recovered files (400GB's worth); for most of this I have an older
backup from 5 months ago; so the problem will be to identify the stuff
added since then.

I guess this is what learning Debian in the "school of hard knocks" is
all about...  This one knocked me out cold.

Well, let's assume that most people buy their equipment rather than
being given it for free.

The HP5M is solely a printer which is fine as far as it goes, but now
I need to buy a scanner, and quite possibly a fax machine, as well.
AFAICT I'd have to use it through a parallel (or serial?) interface.
This laptop has neither. You can network it with 10Base-T for a price,
but no USB connection.

I can see a refurbished one on the web for $340 (if that's the right
model) which is far more than a new AiO.

Ditto. Brian has tried to explain, but I don't completely follow his
explanation. Not being at the cutting edge of mobile phone technology,
I don't have any experience of trying to use it, even if I had an
AirPrint-supporting printer.

This is what's common. Not PDFs. And many take a variety of
stick/cards. Hardly surprising: that's what's inside the
cameras. Thank goodness one's not limited to TWAIN. Ugh.

I'm sure they do. (However, they don't support my printer but luckily,
HP does.) But I don't understand the relationship between linux
printing and gutenprint. Actually I don't know much at all about
printing any more. I used to in the days of dot-matrix, having
happily written character definitions and code to rasterise and
print graphics.

I use gnome-disk-utility to mount the external usb3 drive and then I open
a terminal running Midnight Commander to check that I am using the correct
rsync command, which command I run manually.  Not quite as automated, but
I think it is safer.

I do use a script for jigdo download of weekly ISO images, but those mount
points are on the hard drive and do not change.

You may find fslint useful for detecting duplicates between your old
backup and files in the recovery directory.

I guess so. Using your terminology below, "PDF converter" is ok with me.

So you appear to be saying that what passes through the AirPrint wire

So if a PDF arrives by AirPrint, how does the MFC-J5720DW interpret it
if it doesn't have a PDF converter? (I am genuinely ignorant and confused.)

I'm used to this:

Paper -> scanner -> PDF containing image -> [...wifi...] -> computer

where the PDF is really just a container with an image in it.
And then its converse (but not its inverse):

Computer PDF -> CUPS -[convert]-> BUL -> [...wifi...] -> BrotherPrinter 
-[RIP]-> paper

where the Computer PDF contains some postscript-like code mixed
in with fonts etc which has to be "converted".

So now with AirPrint we have:

Phone PDF -[no-driver]-> [...wifi...] -> AirPrint -[convert]-> BUL -[RIP]-> 
paper

Linux computer PDF -> CUPS -> [...wifi...] -> AirPrint -[convert]-> BUL 
-[RIP]-> paper

but what does the backend of CUPS have to do? Why not just
cp ~/my-file.pdf dnssd://Brother%20Printer...
if you're not bothered about queueing/scheduling etc.

Cheers,
