Alright... so from what I have tried, the Gimp Print drivers do not work with the Laserjet 1000.
I've moved on to try what is explained at this link:
Problem is 2 things...
1. I can't get it to compile properly - lots of errors
2. The getweb doesn't work for me
Therefore, the make install won't work either.
There is a PPD file included with the tar file that I downloaded - I've tried putting it in the printer folder in the Library but no luck with that either. I've also been doing all of this with the printer hooked directly to the iBook so that the extra network complications won't be a factor.
Any other ideas?
