I was setting up an HP LJ4Plus as a printer for Hylafax in OpenSUSE 10.2, and received the error:w2 invalid persAll it needed was a driver change in CUPS. I used the CUPS+Gutenprint v5.0.0 driver Foomatic/hpijs driver, and now it works! Don’t use the Gutenprint one. It clips the output when printing. see above post To get it working with Hylafax, I checked the installed printers by:lpstat -aThis is what it listed:hplj4p accepting requests since Thu May 17 17:16:16 2007I then ran: lpoptions -d hplj4pThis is what it listed:job-sheets=none,none printer-info=‘pr fax printer’ printer-is-accepting-jobs=1 printer-is-shared=1 printer-make-and-model=‘HP LaserJet 4 Plus - CUPS+Gutenprintv5.0.0’ printer-state=3 printer-state-change-time=1179447376 printer-state-reasons=none printer-type=4116Then I ran a test print:prfax:/var/spool/fax/recvq # tiff2ps fax000000001.tif | lpr
