[Post-Install] Cant print

[Wasim]

After the recent update I no longer can print despite printing happily for months. Changed drivers, tried different commands and no matter what I do I cant print. I have 2 printers (Brother Inkjet and HP inkjet), both are experiencing the same behaviour. Either the job doesn't go into the printer queue at all or it does and then prints a blank page 10 minutes later. CUPS issue? Anybody else having the same issue? Any suggestions?

Remove and re-install the printers. My HP goes though a thing once in awhile - like once a year - where it changes it's CUPS name. I don't know why it happens or whether it's the printer or CUPS doing it, but removing and re-installing it seems to work.

Just a follow on ... I've strangely watched the list of printer queues magically change after a reboot. It seems the CUPS discovery system is "misbehaving" . I have 3 printers and had 3 corresponding queues but sometimes I see 5 where 2 of the printers have extra entries magically appearing. Its intermittent. The 3 "normal" ones now work. So I can print but cant explain the random changes

Are any of the three printers 'multi-function'?

[Wasim]

Yes, 2 of them are. (Brother - inkjet, HP - smart tank) What difference does that make?

[Snowhog]

Multi-function printers will often show up in Printers more than once; one occurrence for 'printer', another for 'scanner', and such.
