Hi everybody, I am using debian Sarge and installed recently cups with synaptic.Then I added my HPDeskjet 840C (parallel printer) using cups web interface without troubles.
The problem is that when I try to print a test page nothing happens . There is also a message in cups:
" Printer State: processing, accepting jobs.
"Printer not connected; will retry in 30 seconds..."
Device URI: parallel:/dev/unknown-parallel0

This message appears after trying to restart the job: "client-error-not-possible"
Any help please?

I have the same printer model as yours and I had this exact problem each time I installed Debian. The solution for me was to install pretty much everything that is related to foomatic, gimpprint (I don't recall the exact name of the package right now) and cupsys. Also, not so long ago, there has been introduced some new packages for HP printers, called hpios and hpssd (IIRC), which helps in correctly detecting the printer (not unknown location anymore). When I'll get next to my Debian box, I'll come back with the exact package names.

Hi,
Install the package called "hpijs" everything will work, I have two hp printers and they work very well.
Hpijs is a driver database and has the driver for your printer.

cheers

Thanks for your help, that hpijs package was the key of the problem, now my Hp printer works lile a charm ..... .
I am going to take notes about this packages (it really worths!!)
Debian and Linuquestions rules!!!!

---Glad to hear you solved the stuff with the hpijs package...

As for the client-error-not-possible msg I had a similar issue

Just to point as an interesting thing on how many circumstances does that message appears under.

Greetings
