Gene,

Thanks so much. I had tried the script before and it failed to find my 
printer. This time it worked fine. A typo last time? I don't know. I 
just had to modify the URI, as it sets it up as a USB printer default. 
Maybe browesd was causing issues. I removed that. I have no need for it 
anyway. This ends a headache that should have never existed :)

Are you Gene of LinuxCNC fame?

Thanks for your help.
