Hi I have a long-standing issue with connecting to a CUPS server on a network which has 3 Wifi access points. CUPS server is running Debian 9, tests are with a Debian 10 laptop.
Starting with a fresh re-install of CUPS on the laptop: # apt-get purge cups cups-common cups-daemon # apt-get install cups cups-common cups-daemon If I do this while Wifi connected to AP1, then lpstat on laptop: #lpstat -s no system default destination device for AirPrint_HL_5270DN_Home_golux: implicitclass://AirPrint_HL_5270DN_Home_golux/ device for AirPrint_MP230_golux: implicitclass://AirPrint_MP230_golux/ device for Brother_HL_5270DN_series_golux: implicitclass://Brother_HL_5270DN_series_golux/ device for Canon_MP230_series_golux: implicitclass://Canon_MP230_series_golux/ - all good. Disconnect from AP1 and connect to AP0 and I get: # lpstat -s no system default destination device for AirPrint_HL_5270DN_Home_golux: ///dev/null device for AirPrint_MP230_golux: ///dev/null device for Brother_HL_5270DN_series_golux: ///dev/null device for Canon_MP230_series_golux: ///dev/null From then on it's game over. Can reconnect to AP1, restart CUPS on the laptop but printers showing ///dev/null. Ralph - I know we discussed this a couple of months back - however this condition where the printers are permanently lost is new, I'm guessing following the upgrade to Debian 10 (CUPS 2.2.10).
