This goes into the MIO slot of older HP printers that use the "MIO" style interface, such as the Deskjet 1200 and 1600, Laserjet 4, 4Plus, etc including plotters. I have two of these interface (print server) cards, both for $5.00 plus shipping. Ship should be cheap, not more than $8.00 flat rate in the US 50 states. Paypal and money order only, no checks. Ships from central Kentucky here in the US. Those outside of US should contact me by email (rhb57 -at- alltel.net) or use the PM button below.
