Yes -- snap list does show that I have the CUPS snap installed. Thanks
for the troubleshooting.

FWIW, the list of printers that shows up in the GTK4 dialog is correct,
and I can print without issue to the printers that are installed with
IPP. Their options show up right and printing works. The problem seems
to be specific to printers with custom PPDs/filters, which don't load
options right and don't print. I am not sure how it would have the right
list of printers and how some would work if it was not communicating
with the correct CUPS server, but I don't know how the backend works.

Title:
  GTK4 print dialog does not seem to load filter settings on 25.04

Status in cups package in Ubuntu:
  New
Status in gtk4 package in Ubuntu:
  Incomplete

Bug description:
  The print dialog box in Papers and Gnome Text Editor on 25.04 does not
  appear to load settings correctly from non IPP printers, making it
  impossible to print to devices that show up correctly in CUPS and are
  accessible from other non-GTK4 programs. These are settings like print
  quality, double siding, color/bw, and advanced color adjustments.

  I started using Papers as my PDF viewer after upgrading to Ubuntu
  25.04 where it replaced Evince. I have several printers which use non
  IPP drivers, requiring the installation of PPD and filter files in
  CUPS. These are all set up and working correctly in CUPS, and I have
  no problems with non-GTK4 programs on my computer that are capable of
  printing. I was also able to print with no trouble from Gnome Text
  Editor under 24.10. When I access the CUPS browser-based control
  panel, all the options for my printers are present and working.

  However, on 25.04 in Papers and Gnome Text Editor, the print job settings that are specific to the printer do not load correctly into the print dialog box. Instead of seeing the settings I should have access to, I see IPP default controls which don't relate to my printer's capabilities. When I try to print on Papers, it doesn't seem to throw an error but CUPS never registers the print job, and nothing is actually printed.
  As far as I can tell, IPP printers work just fine.

  I have attached a screenshot of the print dialog in Papers, viewing
  the Advanced tab, attempting to print to a Brother MFCJ6530DW, using
  Brother's driver and filter. The settings that are visible are not
  relevant to the printer and are different from what shows up in other
  programs including Firefox, Thunderbird, LibreOffice, and non-GTK4 PDF
  viewers.
