CUPS (ALPINE) - CUPS claiming print job completed despite printing nothing, How to debug the issue? (network printer, Alpine, Linux, Docker)

vinnu543 · 10-31-2018, 09:42 AM

CUPS version : 2.2.6
Alpine Distribution
printer: Network printer
URI : socket://192.168.20.185

When I try to test print through CUPS GUI, it shows the job is completed despite printing anything.

Couldn't figure out the issue

--> I tried to print it through terminal, with no success.
ping 192.168.20.165 shows the network printer connection is open.

I got the following errors:

lpr: Error - scheduler not responding

lpstat: Bad file descriptor

--> Couldn't access the "view errorlog" page to debug the issue

It says "Forbidden"

How to make the errorlog page work?

Any other ways to debug the issue?

Here is my "cupsd.conf"

Code:

# Show troubleshooting information in error_log.

Listen /run/cups/cups.sock
