Reasonable yes. The two devices look to be an integrated solution as I did find the attached imagePASS datasheet which confirms the job-release/print preview aspect .
hj3, couple thoughts that came to mind reading your most recent post:
- All devices may need to be cabled first and then powered, perhaps in sequence, imagePass and then plotter, or vice versa. The SCSI interface as implemented on most non-disk devices is not hot-pluggable.
- Confirm parallel card is installed and working properly with another printer.
