This time, I downloaded and installed the above RPM using rpm -Uhv as root. It turns out that there were additional RPMs that I had to rpm -e , and then the above RPM installed. Upon execution, I get the following diagnostic: [rosalind568@192 ~]$ hp-setup HP Linux Imaging and Printing System (ver. 3.15.7) Printer/Fax Setup Utility ver. 9.0 Copyright (c) 2001-15 Hewlett-Packard Development Company, LP This software comes with ABSOLUTELY NO WARRANTY. This is free software, and you are welcome to distribute it under certain conditions. See COPYING file for more details. error: HPLIP is not installed properly or is installed without graphical support. Please reinstall HPLIP warning: Qt/PyQt 4 initialization failed. error: hp-setup requires GUI support (try running with --qt3). Also, try using interactive (-i) mode. End error diagnostics. Indeed, the -i mode does work and the printer (and FAX) are now installed. Although the home LAN of the colleague uses DHCP, and thus there is no real guarantee that the ISP will always give this printer (connected via 802.3, not 802.11, to the DSL router / 802.3 repeater / 802.11 access point) the same IP address, the HP application seems to require a fixed IP address and may (probably will) fail if the ISP DHCP server assigns a different IP address to the printer. When I get some time, I will try to find the Qt/PyQt 4 that the HP GUI requires; --qt3 did not seem to work but I will try that again, as the environment should have Qt 3. Thus, I did not need to build from source, but a number of previously installed RPMs did need to be removed. Yasha
