I have a lot of 25 printers all HP Laserjet 2200 with simplex formatter and i want to turn them into Duplex formatter. The simplex formatter board is duplex compatible because if you put paper intro Tray1 and 2 and run an engine test it will pickup paper from tray2 and print the engine test on both sides, so the conclusion is that the formatter "knows" how to print on both sides automatic.The problem is that the engine test runned with paper present on tray 1 is the only duplex printing on that type of formatter. I have tried to use the PJL commands to force enable duplex,no result.I have copied a NVRAM from a duplex formatter, but at the first start-up of the printer with the new written memory it has rewritten it into the default`s of the simplex formatter.The only thing i haven`t done is flashing the firmware because i have not found any firmware available for that printer (the 2200D firmware).
The flashing method is using NETCAT to send the bin file to LPT1. some say it works but noone gave details about the firmware file.
Any ideas ?
