etotheipi,
Thanks, but no joy. I just double checked, and it's not there. This makes sense since my error message is "Unable to locate models.dat file". On the HPLIP site it lists a models.dat file name of "deskjet_1000_j110_series", but I'm unclear where to find the file online and where to put it on my offline computer.
I'm running 32bit ubuntu 10.04 on an Aspire One. Ubuntu gives me one option of using a ppd file.
It's your lucky day! I figured out how to export it from my clean 10.04 system. It should be OS-agnostic, so I don't think it matters what system ultimately uses it.
I just put uploaded it to our new S3 storage space, and linked it for you right here!
