IPP (port 631) is disabled on the new imageFORCE C5140/5150 devices and they are not advertised over mDNS/Bonjour, so the driverless '-m everywhere' recipe no longer works. Document the socket://:9100 + PostScript PPD recipe instead, and note that levels 3 and 5 no longer respond at their old IPs.

CeMM's printers were upgraded to Canon imageFORCE C5140/5150, and the new devices have IPP (port 631) disabled and are no longer advertised via mDNS/Bonjour. The current driverless
-m everywhererecipe therefore no longer works.The devices still accept plain PostScript over the raw socket port (9100) without authentication, so this updates the "Printing from Linux" section to use
socket://<ip>:9100with a PostScript PPD, and notes that levels 3 and 5 no longer respond at their old IPs (ask IT if needed).Verified 2026-09-21 on CachyOS: level 2 prints fine, including two-sided.
