[SOLVED] Cups networked printer not working over network.

exad · 2017-11-16 17:16:19

Hello,

I have installed an old Oki 410 printer on my Arch file server box to share over the network. The printer is installed and can print locally from my file server box using lp command so I know the printer is working. I cannot, however, properly access the printer over my local network and I cannot, for the life of me, figure out what's going on. The printer is found and installed via windows or linux machines on my network but print jobs never seem to get to the printer. I also cannot seem to access the printers cups config from my web browser, 192.168.0.102:631 It's like it's being blocked somehow. I do run a VPN on the fileserver typically, but it is disabled while I try to figure this out.

/etc/cups/cupsd.conf:

If there is any other info I can provide, please do not hesitate to ask.

*UPDATE* I managed to solve the issue quite simply by issuing the commands:

$ sudo cupsctl --remote-admin

To get remote administration working and:

$sudo cupsctl --share-printers

To get the printer shared properly.

I didn't happen to notice these two commands anywhere in the wiki and and seems a lot easier than editing the cupsd.conf
Hopefully this will be useful to anyone else having this issue. I can now print from any computer on my local network.
