Given the prevalence of issues related to Sonoma suddenly halting printing on non-AD bound machines, I decided to start fresh and encountered the same problem.
To resolve this recurring issue, I recommend starting anew by initiating a "Reset Printing" process. This comprehensive step removes ALL printers and queues. Along with clearing all Keychain entries associated with printing, ensure that the PaperCut client is installed and operational.
Follow the provided instructions diligently. When specifying the URL for the queue, make the following adjustment:
Change: smb://sfuprint-p.mps.sfu.ca/SFU_Print_non_AD_auth
To: smb://sfuprint-p.mps.sfu.ca/SFU_Print_non_AD_auth?encryption=no
This adjustment should help mitigate the printing interruptions experienced previously.
It is one continuous line, without breaks. After adding the printer, you can perform a test print, and the printer authentication prompt should appear. I utilized "ADSFU<username>" and encountered no issues.
Next is papercut authentication
and finally, information that our job is waiting for us in papercut queue
Hope this helps.
