Subject: Re: Hp print anomoly (SOLVED but whew!)
Jose-
Thanks for the tip and sorry I did not thank you earlier, I thought that
I had.
Anyway the problem was that I had the "fast text printing" box checked
in the printtool for this printer.
Still trying to figure out what all goes on here. This is what I have
come up with so far and it can't be right, can it?
(lp is a remote hp5si using jetdirect card and lj4 filter)
When I do:
#man autorpm |lpr
man somehow knows that the standard output is not the destination and
groff is used to format output (not sure where groff fits but I know it
is there somewhere) I believe the page footer is here at this point
since it is there when I do a man autorpm > autorpm.man and less
autorpm.man
---
Correct, but for even prettier output, try the following...
#man autorpm -t | lpr
You might have to hit the continue button on the printer... do so..
---
lpr spools its input to the default printer lp
the /var/spool/lpd/lp/filter script is used to try and determine what
type of file it is.
if fast ascii text is on then the asc-to-printer.fpi script is called
and after changing the CR to CR/LF using sed the data is dumped straight
to the printer (I guess in the filter script)
My guess is this is where I was getting an extra linefeed that was
causing all the pagination to be off.
Now the fun part. if not fast ascii text then the filter script does
cat - |asc-to-ps.fpi|ps-to-printer.fpi
that converts the ascii output from groff into postscript and then uses
ghostscript to print the postscript.
Wow! Even if I am close I had no idea.

Right on the money... that's whats so "cool" about it... Linux turns your HP
into a Postscript printer via Ghostscript...
I use this "feature" all the time... I have Winblows/Samba clients printing
Postscript output to my Ghostscripted HP(s).... you actually get better
grayscale this way... plus a few other features, such as page thumbnails...
The "man -t" takes it a bit further letting groff/troff preprocess the MAN
page output for final postscript to hpgl rasterizing...
Seemingly a very roundabout way of doing things, yet it works so darned well
in Linux...
---
I did not find the fast_ascii_text test in the filter file since I was
on the track before I really got into it and running the printool
changed the filter script. at least vi complained when I got out of it.
I got on the right track after finding the DEBUG_* variables in the
filter file and setting them to 1, printing, and then looking in
/tmp/filter.debug.
Again thanks for tip of looking in man printcap it got me started down
the right path anyway.
