A Fast Infrared Receiver model C4103A for HP LaserJet 4050, 4100 & 4550 series.
I dont have a manual just the receiver, velcro, pink anti static bubble wrap inside the standard silver anti static bag.

Trade for two 168 pin 32 MB Dimms. I have no way of testing this puppy, so
if anyone is willing for a trade I'll send them the unit first to try. If it works then send me the dimms after

Heres the write up from the website:

The HP Fast Infrared Receiver for the LaserJet 4050, 4100 &
4550 series allows mobile users wireless walk-up printing from
PDAs, laptops, palmtops, handheld scanners - and even digital
cameras that are IrDA compliant. Perfect for offices that have
mobile users who need cable-less printing.

Thanks
