Weirdness when printing from a 3489 to a LaserJet

["James H H Lampert" <jamesl@xxxxxxxxxxx>]

I was wondering.

I have an old HP LJ4P printer hooked up to my 3489. Most 
of the time, printing works fine, but every once in a 
while, something prints weird: large blocks of space 
disappear. Most recently, this happened when I printed a 
member list from the PDM (using the print key). The spool 
file was a nice, neat table in WRKSPLF, but when I sent it 
to the printer, the lines looked rather like train wrecks: 
all the white space (other than the spaces within the text 
column) had been squeezed out.

Can anybody explain why this would happen, and how to fix 
it?
