Problem with cups-filters - CUPS 2.4.2 #585

Open pclinuxer opened 5 months ago

pclinuxer commented 5 months ago

Describe the bug CUPS 2.4.2 will not print, the cause being "Filter failed".

See here: Problem: https://lists.cups.org/pipermail/cups/2024-May/075402.html Solution: https://lists.cups.org/pipermail/cups/2024-May/075403.html

To Reproduce Try to print (Samsung M2020W printer) in a Linux system with CUPS 2.4.2 installed. If the libcupsimage2 package is not installed, cups-filters will fail and CUPS will then remove the printer as shown in the last line of the dmesg output. 

~$ sudo dmesg
--- snip ---
usb 5-1: new high-speed USB device number 10 using ehci-pci
usb 5-1: New USB device found, idVendor=04e8, idProduct=3321, 
bcdDevice= 1.00
[usb 5-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3

proto 2 vid 0x04E8 pid 0x3321
usblp1: removed       # last line
~$

Expected behavior The expected behaviour is the one I get once I install the libcupsimage2 package. ie: CUPS will print without any issues, printer is not removed.

Screenshots N/A

System Information:

Additional context CUPS 2.4.2-3+deb12u5 is the *.deb package present in both Debian Bookworm and Devuan Daedalus repositories. It will not work properly if the libcupsimage2 package is not installed.

~$ aptitude why libcupsimage2
i   cups            Suggests    foomatic-db-compressed-ppds | foomatic-db
p   foomatic-db         Recommends  printer-driver-all                       
p   printer-driver-all      Recommends  printer-driver-splix                     
p   printer-driver-splix    Depends     libcupsimage2 (>= 1.4.0)                 
~$

From what I can make of the above aptitude printout, cups suggests foomatic-db / foomatic-db-compressed-ppds which in turn recommends printer-driver-all.

In turn, printer-driver-all recommends printer-driver-splix but this last package depends on libcupsimage2.

TL;DR CUPS will not work properly because the cups-filters package fails if the libcupsimage2 is not installed.

It would seem (?) that cups-filters depends on libcupsimage2 but it is not a dependency. See here: https://packages.debian.org/bookworm/cups-filters

Does it make sense to have to install three unneeded packages (foomatic-db-compressed-ppds | foomatic-db, printer-driver-all and printer-driver-splix) to get libcupsimage2 installed and CUPS 2.4.2 working properly?

But you know better than me with respect to all this, so please have a look. 8^)

Thanks in advance.

Best,
