Unbelievable: After years with Ubuntu-12.04 to 16.04, followed by Linux
Mint up to 19.3 (Ubuntu 18.04), I switched to a fresh new install of
Lubuntu-19.04 a week ago... and have this strange printer disappear
problem for the first time ever!
Today is May 18th, 2019 - that is eight years(!!!) after the last entry
in this list.
How can that be? What's wrong?
--------------------------
My printing system for the last 12-15 years based on cups with the
following setup:
* 1 network laser printer
* 3 "symbolic" printers which are a copy of the former, to set defaults for
particular uses: "monoprinter" (grayscale), "colorprinter" (full color) and
"labelprinter" (use of manual feed)
# lpstat -s

Besides the different settings in /etc/cups/printers.conf, the DeviceURI
is the same for all four while the UUID differs:
<Printer Brother_MFC_9142CDN>
UUID urn:uuid:f81a64b6-71d2-3878-71cf-1b1fd6b4dba3
DeviceURI ipp://BRN30055C78CF3B.local:631/ipp/print

<Printer colorprinter>

</Printer>
<Printer labelprinter>

</Printer>
<DefaultPrinter monoprinter>

</DefaultPrinter>
Any help / hint / solution is highly appreciated - TIA.
