no printer output (Pro9500 mk ii)
When I print something, I see it land in the printer queue, and I see
the blue light blinking on my Canon Pro9500 Mark II printer. After a
while, gimp says that printing has completed, but nothing ever comes
out of the printer.
I can print a test page from the Ubuntu driver, so this looks like a
gimp/gutenprint problem.
gimp 2.10.18
flatpak
Ubuntu 20.04
I gave up with the flatpak Gimp, great if you just want a vanilla Gimp, but since it is 'sandboxed' too much hassle importing files from outside 'home' and side loading library files for plugins like gimp-gutenprint. Never got xsane to work for a scanner, too many dependencies. Not sure I got anything to print either. Kept an old regular gimp as a work-around.
However, light flashing on your printer, so it is receiving data, but no print output. When that happens to me, it is a file stuck in the print queue preventing any subsequent file(s) to print.
