I'm trying to set up network scanning on printing/file share server running slack-10.2. This it seems cannot been done using hplip with hpaio so I've gone back to using hpoj.
Before setting up on server via ssh I decided to familiarise myself with hpoj on one of the clients. After running ptal-init start and ptal-cups and restarting cups I can find my scanner but when trying to install a printer (just to see how its done) I am presented with two usb printers, one which is connected and one that is not but had been previously. Thinking there might be something hanging around from when printers were hooked up but which I couldn't find now, I uninstalled cups, then deleted anything displayed when I ran "whereis cups", then reinstalled cups.
These printers are still showing up as usb printers in cups when trying to add a new printer and the printer as a ptal device is not displayed.
This PC is no longer configure in cups as a client. I'm wondering where these printers are coming from and that maybe until I can get rid of this I will not have cups recognise the printer as a ptal device.
Have you tried uninstalling it via the CUPS web interface? Just out of interest, is hplip incompatible with what you need, or is just trying to get it to work on Slackware? I wrote a how-to on configuring hplip on Slackware for an all-in-one usb hp device. It's in the tutorials section. If you need networking capability I think you have to install net-snmp first. I've only configured it myself without net-snmp by installing it with the --disable-network-build switch.
Thanks for the reply, Yes, I did uninstall via cups web interface and did an /etc/rc.d/rc.cups stop (then start) , later that day I did a reboot and they were gone.
I had seen your howto while googling. I've used hplip successfully since slack-10.0 but it was working it on a standalone server for sharing scanner that caused the grief. I've compiled and sorted out hpoj for scanner shares and will leave it at that. It would have been nice to use hplip with ssh with -X to check on cartridge status.
AFAICT hplip can't be used on a standalone server, at least with my hp-930c. I posted on the hplip site about this problem the same day as posting here and my questions were either to silly to respond to or else no-one had a clue.
It has been awhile since I made this post and the problem was resolved albeit I don't remember exactly how.
But I don't like googling up unresolved threads when I have a problem so I should at least leave a link here to my notes from when I successfully set up network printing and scanning for anyone who hits this thread even though it may not address this problem specifically.
