> -rw-r----- 1 root lp 131822 Dec 14 13:17 MX860.ppd There is nothing wrong here. A PPD is not readable by a user process, only by one with root privileges. Whatever you ran did not have root privileges.
You are using the gutenprint PPD for MX860; no problem there. Now do lpadmin -p mx860 -v socket://<IP_address_of_printer:9100> -E -P /etc/cups/ppd/MX860.ppd and print with lp -d mx860 /etc/nsswitch.conf I am guessing that the Canon printer accepts jobs on port 9100 - most printers do. You could also set up lpadmin with -v cnijnet:/00-1E-8F-74-5A-78 and see how you go on. -- Brian. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1808581 Title: cannot print to Canon MX860 after upgrade to Ubuntu 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1808581/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
