When I first switched the printer on after installing Ubuntu 7 I thought it was going to work. But only the first 5 lines of a document were printed than the printer stopped/stalled. I tried again - no response. I tried to clear the print queue but got an error message 'Cups server error There was an error during the CUPS operation: 'client-error-not-possible'. I then tried to reconfigure the printer but really don't know what I am doing. The change drivers window offers 4 choices:
foomatic/hpjs (recommended)
CUPS + Gutenprintv5.0.1 (simplified)
CUPs + Gutenprintv5.0.1
Foomatic/cdj550
I can't get any of these to do anything, probably because I can't clear the print queue. But I don't know what the options on the next window mean, e.g. Change Driver window with the 2 options:
Use the new PPD as is, etc.
Try to copy the option settings ....
What's this all about and which of these options should I choose?
Any thoughts on how to clear the print queue and avoid the error massage?

I think one of the printer configuration options I tried (at random) must have done the trick. After a reboot the printer is printing!! Now to sort out the internet connection!!

I may have sorted the printing problem on the host computer, but that has disabled printing on my laptop which used the PC as host. Any suggestions for how to sort this?
