Why the fricking RICOH printer doesn’t accept my job???

I check it on openprinting, it said "perfectly work🐧🐧🐧 "

I check it on my university website, it said " connect to campus wifi … blah blah… set up locked printing …"

The gnome control center doesn’t detect any printer, so I manually added the printer. It even said where it is located. It must be a good sign that the printer is supported? NO.

I test print with locked printing (as it required), however, it doesn’t show in the job list.

I sit in the library, staring at localhost:631 on my laptop, and it said data sent. But why?? Why ??? The printer doesn’t show up my job. It’s 2024 and it is a modern printer… and I can not print a sexy photo of Keisei Skyliner from linux ^TM

Fruck!!!
