We have added an infrared module, HP code 82242.
This was a very good idea from HP. If you have used one of the printers with cable (of which we have also a couple of units), or the HP-IL connection, you would agree that it was a much better idea to have a wireless printing.
The module is fully compatible with the HP41cl (tested!) and with both HP82240A and B printers (which are available at 99 € new in our web too)
You will find it in the HP41c corner.
