I have a HP OfficeJet K80xi "all-in-one" USB printer. When I send a file to the printer from a virtual console using the command : lp "anyfilename", the response is "request ID is HPOJK80-7 (1 file(s)". There is no printer action, no sound, nothing. The printers name is HPOJK80; the -7 is the job number. The command lpstat shows there are a total of 7 jobs in the queue. The command lpq response is "HPOJK80 is ready and printing", and lists the 7 file names. Nothing has ever printed since I switched to CentOS5. The hplip web site (http://hplip.sourceforge.net/) tells me to do "rpm -qa hplip" from a virtual console. The result is "hplip-1.6.7-4.1.e15" (driver model installed). The web site table shows any driver later than 0.9.5 should work. The hplip web site also states that there are 6 "dependencies": xsane, cups-devel, libjpeg-devel, pyqt, pyqt-devel, and net-snmp-devel. Using the find command (find / -name 'filename' -print) results in 2 hits for xane, 0 hits for the others except libjpeg-devel which gives the message "/proc/11268: No such file or directory". My conclusion is there are 5 missing files, probably cups-devel is the most important. Where can I find the missing files? How do I know where to put them? While I am not sure that "system-config-printer" was run correctly, I am going to concentrate on the missing dependencies. Any help would be appreciated. Thanks in advance. Bob T.
