68.5 Sharing a Printer on the Network

20190812 First, check the current status of the CUPS system configuration on the server where the printer is connected and known to be functioning:

$ cupsctl
_debug_logging=0
_remote_admin=0
_remote_any=0
_share_printers=0
_user_cancel_any=0
DefaultAuthType=Basic
JobPrivateAccess=default
JobPrivateValues=default
MaxLogSize=0
SubscriptionPrivateAccess=default
SubscriptionPrivateValues=default
SystemGroup=lpadmin
WebInterface=Yes

Notice that _share_printers=0. To enable printer sharing on the server use the command cupsctl.

$ cupsctl --share-printers

$ cupsctl | grep share_printers
_share_printers=1

When sharing, CUPS will allow printing from other hosts on the same local subnet. On another computer check that the connected printer is now available:

$ lpinfo -v
...
network dnssd://HL3040CN%20%40%20theano._ipp._tcp.local/cups?uuid=a67769fe-3acb-327c-7ffa-67eeb2bd318b
...

The printer is identified as HL3040CN_theano, for example, where theano is the name of the host server. The printer may now automatically appear as an option on any print dialogue.

Printers are shared by default from the server but if it is not then share the printer using:

$ lpadmin -p HL3040CN -o printer-is-shared=true
