I'm don't know what you mean by a "standard RS-232 serial cable", but you can get the computer and printer to communicate by using a null-modem cable. Any decent cable supplier should have one availble or be able to make one very quickly. If you want to make one yourself look in computer books for diagrams or see message 47524 in this group for a schematic. > Thanks for your help. You're welcome. -- Richard L.
