There is an option in the paintjet driver to do 'direct LPT printing',
which must be manually turned off to print to a LAN or HP-IB or anything
other than a real LPT port.  Go into control panel, select your printer,
select configure, setup, options (something like that anyway...) and 
turn off the direct lpt printing option.

The other thing that can go wrong and show these symptoms is when 
Windows thinks it can talk directly to your hardware (i.e. lpt3) 
instead of going through the device driver (i.e. LAN).  To trick
windows into talking to the device driver instead of your hardware,
'connect' your printer to LPT3.PRN= instead of LPT3:=

One last comment - make sure you do not have more than 10 entries
in the [ports] section of your WIN.INI file.  Windows will not
complain, but entries after the 10th will not necessarily work
properly.  This is actually hidden deep in one of the .TXT files
windows installs.  Funny - the default windows setup contains
more than 10 entries...

Hope this helps -
