The printer works perfectly. HP supports Linux, so downloaded the drivers and software. Have an HP tray icon near the date on the menu panel now - pretty cool!
A few days later got a notice from HP that there was a download upgrade so downloaded and installed it.
I was amazed at the test page print out. It was improved from the first test page. Has lots more information, detail, and better graphics. This printer was purchased in 2006 and they still support it - remarkable!
