Hi:

Something similar happened to me with a report that had a preview before 
printing which didn't print in one particular machine.  The preview opened
and quickly closed by itself while it worked fine in all other computer in
this
particular site.

The problem was a program called PC PItstop which the user added the option
of Supershield, a memory resident program that, according to the company 
statements "access program and files in real time for potentially unsafe
operations".
Well it thought the report was unsafe apparently, remove it and the problem
went
away.  Maybe some program like this or an antivirus is running that is
blocking the print job.

OK, I can't see how that happened so for now I'll rule it out as a
possibility.

I'll try out the uninstall/reinstall next week.

I will check that too.  The job is really small: a bar code, a name and a
couple short lines of text to print on an address label.
