Reading the linked Calcomp Manual, the scanner is scsi model, not a parallel
port model. All he needs is scsi card and scsi cable with proper end
connectors for card and scanner. The two ports on the scanner are for
connection to the card and connection to any scsi device daisy-chained to
it.

I have an older HP scanner, and it has a DB25 connector for SCSI.
A DB25 connector is just one standard for SCSI and it is true, a
DB25 connector is also used for parallel printer ports.

SCSI can also be daisy changed and why there is second DB25 connector
on your scanner.

His scanner probably connects to a printer port, as mine does. The second
DB25 is to allow a parallel printer to be used on the same port.

I have a SCSI external hard drive unit that connects to the computer by a
printer
port.
