[cups.general] How to send jobs to a SCSI printer with cups?

[JW]

Just curious, but have you found a solution to this? I have a SCSI ID card printer (nisca PR5100) and when i run an (exec) command similar to yours, I get the same problem.

I can tell you that the LCD on the printer tells me:
"Unsupported Print Command".

Thanks
