libglade2 I was able to get the cannon drivers to install per the instructions:
dpkg -i cndrvcups-common_2.70-1_amd64.deb dpkg -i cndrvcups-ufr2-us_2.70-1_amd64.deb /usr/sbin/lpadmin -p Lisas_Printer -m CNCUPSD490ZS.ppd -v lpd://192.168.1.150/Lisas_Printer -E
Then when I print a test page from the printer properties window under Ubuntu, I see the following status:
Idle - src = libcanon_pdlwrapper.c, line = 514, err = 0¥nDEBUG: PID 2262 (pdftops) exited with no errors.
I have tried removing and reinstalling, updating the system files, and am not sure how to dig into CUPS to debug further. I am sure others must be encountering the same problem if you have a canon printer.
Thanks in advance for any insights you can share.
