I've got a USB printer (HP LaserJet 1018) connected to my Windows 7 desktop. I also have a USB infrared adapter (Actisys ACT-IR224UN-Li) which presents itself as a raw serial port, currently COM3.
What are my options to have Windows act as a print server listening on this virtual serial port, so that I can print from older devices that use raw SIR infrared?
None of these would be IRDA-capable devices. I would also need to be able to specify no hardware flow control on the port, as this adapter uses those lines to control the baud rate of the IR transceiver.
Most of the devices would be running MS-DOS, so there's definitely no LaserJet 1018 drivers nor bluetooth. RS-232 is an option, though, and they do have some form of "LaserJet" driver in most cases.
