This happens to me on both Suse 10.2 and Ubuntu 7.04.

I could only accidentally found how to fix it when my son, who was so
frustrated waiting for me to fix the printer, used the Windows notebook
to print his project. After that I could print from Linux ( Ubuntu or
Suse ). 

Ahhhh, I just read your URL and found this note:
----------------------------------------------------------------------
The firmware of the printer must be uploaded after turning it on. You
can use a hotplug/udev script which comes with foo2zjs, or do it
manually: "cat /usr/share/foo2zjs/firmware/sihp1020.dl > /dev/usb/lp0".
----------------------------------------------------------------------

This confirms my thought. I am going to try it tonight. My son asked me
to install Windows before I leave for SF next week if I cannot fix this
problem. Now I think I can. :)

Thanks, CM.
