I have a HP PSC 1510 inkjet 3 in 1. Installed hplip and some cups libraries (maybe not needed). manage printing does not work (website refuses connection). Adding it with hp-setup from terminal finds the printer, need to manually select the PPD but it the just returns to the terminal… With a red error that it couldn’t find the correct PPD file.
If I need to disable the FW then please give me the command for that too…:-p
