I recently ordered a USB to serial adapter for a Honeywell PC43 printer and was told that it had been obsoleted without a replacement. I confirmed this with tech support but the marketing department says that the part is still valid. In any case nobody has this adapter in stock and until this is straightened out there is another USB adapter that works.
I plugged in one of the old cables (part # 203-182-100) into my PC and saw that is used an FTDI driver. I found this cable on Amazon that used the FTDI chip set , plugged it into my PC43 and it worked.
If Honeywell does continue to supply 203-182-100 you are probably better off buying from them for support reasons, but this cable does work in the interim.
UPDATE 7/27/18: Honeywell has fixed this issue and this cable is now available from them.
