OK lets try (on oldlap, where I tried yesterday and previously today) 1. Remove all printers (via cups) 2. hp-makeuri 192.168.1.50 CUPS URI: hp:/net/Officejet_7300_series?ip=192.168.1.50 SANE URI: hpaio:/net/Officejet_7300_series?ip=192.168.1.50 HP Fax URI: hpfax:/net/Officejet_7300_series?ip=192.168.1.50 3. Install (via cups) hp:/net/Officejet_7300_series?ip=192.168.1.50 Prints fine. 4. xsane hpaio:/net/Officejet_7300_series?ip=192.168.1.50 WORKS !! 5. xsane no arguments WORKS !! Let's try ajglap now (main laptop) 1. Remove all printers (via cups). 2. hp-makeuri 192.168.1.50 CUPS URI: hp:/net/Officejet_7300_series?ip=192.168.1.50 SANE URI: hpaio:/net/Officejet_7300_series?ip=192.168.1.50 HP Fax URI: hpfax:/net/Officejet_7300_series?ip=192.168.1.50 3. Install (via cups) hp:/net/Officejet_7300_series?ip=192.168.1.50 Prints fine. 4. xsane hpaio:/net/Officejet_7300_series?ip=192.168.1.50 Works 5. xsane no arguments Works Walt and michael, thanks so much. Walt, At least for me hp-setup is now replaced by hp-makeuri/cups as the favorite way to reinstall printers after an hplip or cups emerge. Again thank you. I can remember the last time I could print on both printers from all three system and could run xsane on all three as well. allan
