I've searched through the archive and find a number of similar threads, for example http://thread.gmane.org/gmane.comp.printing.hplip.user/2177, but I can't find any resolution.
I've installed hplip using the latest Slackware binaries, which I'm using without any modifications on my part. My printer is a F2180. As with the other thread, I turn on the printer and udev/kernel creates /dev/usb/lp0 and appropriate messages are written to /var/log/messages. I then print out from my application (various KDE programs) and the job prints correctly. However, /dev/usb/lp0 is then deleted, and hpiod: removing usblp driver interface=1 for hp:/usb/Deskjet_F2100 io/hpiod/device.cpp 504 kernel: drivers/usb/class/usblp.c: usblp0: removed is written to /var/log/messages. So when I try and print the next file, the device no longer exists and the printout doesn't work. The printer has to be switched off and on again, so that udev recreates /dev/usb/lp0. However, I do not have this problem if I print via a file. So, if I print from my application to a PS file, and then print that to /dev/usb/lp0 with a similar gs cmd to the one the HP driver uses, such as: gs -dSAFER -sDEVICE=ijs -sIjsServer=hpijs -sDeviceManufacturer=HEWLETT-PACKARD -sDeviceModel="deskjet 3320" -dIjsUseOutputFD -sOutputFile=/dev/usb/lp0 -dNOPAUSE -sPAPERSIZE=a4 -r300 -- print.ps then it prints fine and /dev/usb/lp0 is not deleted. I know next to nothing about how all these pieces of software fit together (or not), but from the entry in /var/log/messages it looks as though hpiod is telling udev/kernel that the printer is switched off. I can see that it might need to send a 'printer idle' msg after each print job, but why 'printer off'? In case it's relevant, I should perhaps also say that I have not yet installed pyqt (I need to rejuggle the partitions to make room, and don't have time for that at the moment), so am not using the full hplip software. ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
