Silly boy...
My Epson Stylus Photo was out of ink!!! Gasp! How embarassing...
I rebooted under Windows and still couldn't print. But the Zip drive worked.
This was looking suspicious. So I plugged the printer into the other linux
box and got the same error message.
Two wrong assumptions were made:
1) Because the printer stopped working just when I was doing unorthodox (and
maybe dangerous) things with root privilege, I assumed that these activities
were responsible for the failure.
2) I assumed that something like a printer error would not produce the
symptoms I was getting.
So remember, before you call the garage, look at the gas guage.
Cheers,
Greg
