Yep...most likely PEBKAC...either that or internet search-fu requires additional training. HP printers, especially older laserjets, are well supported. Besides CUPS, you will also need HPLIP to provide the correct printer ppd, filters, and URI. For many HP printers, CUPS will not have the "drivers". As postcript printers, you might be able to get CUPS to work with a generic ppd. Same for PCL5. The interface URI will be the tricky part. I have a HP LJ m1212nf MFP (Vintage 2010)and network print, scan and fax works - well fax did a few years ago ;-) HPLIP support is: https://developers.hp.com/hp-linux-imaging-and-printing/supported_devices/index HP LaserJet 4050n Printer HPLIP >= 0.9.5 Full (End of support) USB connection HP LaserJet 4100n Printer HPLIP >= 0.9.5 Full USB connection Note that network, parallel IEEE-1284, RS232 printing is not supported on Linux.
