A bit off topic, but I'd be interested in hearing from anyone who has setup a Multi I/O card on a 256x printer. I have a cheat sheet that shows what the interface settings are: 20: 00 38400 Baud 01 19200 Baud 02 9600 Baud 03 4800 Baud 04 2400 Baud 05 1200 Baud 21: 00 8 Bit, No Parity 01 8 Bit, Even Parity 02 8 Bit, Odd Parity 03 7 Bit, Even Parity 04 7 Bit, Odd Parity 22: 00 Normal Operation, Software Handshake=None 01 CTS Ignore, DTR always on, XON/XOFF Protocol 23 00 Parallel Port Config 24 00 Parallel Port Config 25 00 Buffer Config 26 00 PCL Emulation, Auto LF on Buffer Disable 01 HEX Dump, Auto LF on Buffer Disable 02 Epson Emulation, Auto LF on Buffer Disable 27 00 Character Sets & Paper Control 28 00 USA Character Set 29 00 Active Port = Parallel 01 Active Port = Serial The problem our client is having is that the printouts (connected to an NT server, via the parallel port, Generic/Text only printer selected) print (2) of every character. Apparently, he has tried changing most of the settings with no luck. I'm not sure exactly what settings 23 & 24 configure in the parallel port, and I'm thinking the problem may be in these settings. Any help would be greatly appreciated. Mike Cornwell [log in to unmask] 800-474-7397 619-603-0148 Fax
