Just curious. Do you plan to actually use the P-40 or are you a collector? Be aware that operating a thermal printer on a regular basis may be slightly more expensive than a dot matrix/inkjet/laser. Archiving your printed copy may be a problem in the long run (keep it out of the sun). You can still get a parallel to serial converter cable from 'Black Box". Be aware that parallel interface data is a one way street. However, some parallel printers do support 'nibble mode' that lets the printer talk back to the host.
