WLAN-Printer works a little

[Formicula]

Hello, anybody out there with an idea for a command to make the WLAN-Printer (HP-Officejet)
work again when it stops after 30 Min - 2 h.
Simple stopping the print job and print again does not help.

The only way for me is to stop the print job and RESTART.
Then it works again 30 Min- 2 h.
I use updatet lucid lynx 32.

And I need a command like "killall pulseaudio" that I need when I
return from logged-on as the second user to get sound again.

Thank you.

Regards,

I watched top before i stopped the successless print job!

And made then:

sudo killall hp

and

sudo killall gs

Both commands give "No Process killed"

but it works again after
