HP communication issues - "Device communication error"
by Jeebizz from LinuxQuestions.org on (#5QRTA)
I notice via HPLIP, that the connection or communication to my printer is randomly lost at times. I have also attributed this perhaps to the firmware updates - sadly these firmware updates are security updates so I cannot really just ignore them, but then again maybe that is not he case I do not know - because usually a security update shouldn't affect functionality, but then again prior me to applying the last security update from HP (firmware) , I did not have this sort of problem.
Since I am on Slackware 14.2 I am using stock HPLIP which is version 3.16.5, and yes after a few minutes, the printer itself does go into 'power saving' or 'sleep' mode by default, however that shouldn't affect me printing, because it is set to wake and print when a print command is sent. Again though I can only attribute to the loss of communication via the last firmware update; and really the only solution is to remove the printer from HPLIP and reinstall it, because the status of the printer always shows 'stopped', and me trying to start the printer gives me an error, as if it isn't a valid command being sent to the printer. I haven't actually tried the diagnostics utility either from HPLIP, I guess I should have.
So I mean my question is what is another way of working around this issue, until Slackware15.0 is out with a later version of HPLIP? Again also to reiterate, normally I don't apply firmware versions for any sort of functionality - the firmware updates I get from HP specifically are just security updates, and if anyone is wondering the type of printer I have is an HP M553 color laserjet.
This is a sample of HPLIP's log:
