IBM ProPrinterII 120 120 Ribbon Cartridge, Optional Serial/Network/Parallel/Additional in us-ascii A ibmpro Easy to get working on serial - just dump straight ASCII. If you have the parallel module installed, you need to use magicfilter which has a ProPrinter / ProPrinterII specific filter which fixes some minor oddities. Fair warning; the serial interface drops characters frequently. Don't use it on the network if you can avoid it. ;)
