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.

Yes, these scanners were only SCSI. And I'm not even sure you can get it
working with a standard SCSI board in your PC. You are probably 'locked' to
the SCSI board that came with the scanner. In those days that wasn't
unusual - even HP delivered scanners with proprietary SCSI boards.
