We just installed a new computer into our network and have experienced a few problems printing from it.  The new computer uses windows xp while the older computers use 2000 professional.
When printing sales acknowledgements, packing lists, invoices, and purchase orders, the line items sometimes don't print from the new computer.  We have not been able to duplicate the problem from any of the older computers.  And it gets even stranger.  For example, we usually print 2 copies of each purchase order.  The first copy will print correctly, and the second one is missing the line items.
 
Any suggests as to what may be happening and how to fix this?
 
Thanks

This is a networked printer.
