Spent too much time on this so I'll ask: What is the trick to installing a HP 7410 OfficeJet on Ubuntu? I can ping the printer; the driver was readily available and has been installed and installed again; Ubuntu says everything is OK. Cannot print any documents including the Test Page. The printer is on a home network as is the Ubuntu machine. All Windows computers access the printer with no problem. Also, I can access the HP 7410 toolkit/support (built into the firmware) normally by using a web browser and entering the printer's address on the network. Same procedure used in windows.
