CUPS doesnt work anymore with my HP Printer

[Rainer Weninger]

With 22.10, the autogenerated PPD has much more info inside then with 23.10. My printer needs about 5 Minutes now to start printing and prints only black and white, no colour.

I was able to reproduce the bug with the IPP printer emulation utility ippeveprinter (package cups-ipp-utils).

It is actually 2 bugs: One is that cups-browsed (which automatically creates a CUPS queue for your printer) sends PDF and not Apple Raster to your printer, and your printer is slow on processing the complex PDF format. I have done a fix on the upstream code now that if the destination printer supports both Apple Raster and PDF, the former gets preferred. This way the computer and not the printer renders and rasterizes the PDF input, and the computer has usually a much higher performance for doing this work.

Upstream fix in cups-browsed:

https://github.com/OpenPrinting/cups-browsed/commit/3eb66da

The monochrome output is due to a bug in the PPD file generator for driverless IPP printers. If the printer reports "auto" as default for the color output mode, it selects gray instead of RGB as default. This I have fixed in libppd now:

https://github.com/OpenPrinting/libppd/commit/1934a6c341

These fixes will be included in the next uploads of libppd and cups-browsed.

This bug was fixed in the package libppd - 2:2.0~rc1-0ubuntu1

---------------
libppd (2:2.0~rc1-0ubuntu1) lunar; urgency=medium

  * New upstream release 2.0rc1.
    - PPD generator sets default color mode when printer attrs say "auto"
      now (LP: #2014976).
    - ppdLoadAttributes() finds the default page size also by size dimensions
      now (LP: #2013131).
  * Removed patches as these fixes are included upstream.
  * Updated libppd2.symbols.

I applied the fix, but still have the issue that printing takes ages.

Also I still cant print in colour.

Interesting is, when I delete the job in the print queue, the printer starts printing ASAP.

Also I tried with Ubuntu 22.10, there everything works perfect. I got 2x Ubuntu 22.10 where it works and 2x Ubuntu 23.04 where it doesnt.

This bug was fixed in the package cups-browsed - 2.0~rc1-0ubuntu1

---------------
cups-browsed (2.0~rc1-0ubuntu1) lunar; urgency=medium

  * New upstream release 2.0rc1.
    - Prefer Apple Raster against PDF when destination printer supports
      both (LP: #2014976).
    - Fixed crasher in implicitclass backend.
  * Removed 0003-implicitclass-backend-init-header-pointer.patch,
    included upstream.
  * Updated AppArmor profile, as with libcupsfilters 2.0rc1 cups-browsed
    executes ippfind and echo, so allow the execution under the same
    restrictions as they are already applied to cups-browsed itself.
