Error when Printing Adobe docs....

[James McDonald]

Hi I get the error below when attempting to print... pdf documents... if I 
print to my generic printer in RH7.2 it prints part of this message on the 
piece of paper. If I print to a file this is the output that Ghostview 
gives.... when I try and open the ps file.

I was wondering if anyone can let me know where to start looking... My first 
step is an upgrade to ghostview... any suggestions gratefully received.

James
