It's might be a SCSI port, since it has too many pins for an IEE-488 Centronics-24. Since LaserMaster appears to have been using a PostScript clone it's likely it was for linotronics as well as dumb laser printers as you said. It's more likely that it's the same DB-37 connector on bigsadhu's card.

ISTR it being used for making HiRes positives on Laser Printers for photo resists for silk screen printing. I don't remember if LaserMax was the distributor of that turnkey system or not, but it makes sense that they would have chosen that name if they were bundling a LaserMaster interface card.

Nice conquest there. Please let us know about the connector type. Also. please run Slot Info from the Gauge Series or the like to read the card's Declaration ROM info. That should determine the identity of the card better even than the silk screen layer or DeclROM version/copyright tag text.

This patent probably explains how the card achieved higher resolutions from standard Laser Printers, likely from a different system hack. but they may have licensed this from Kodak or some other process, considering that they licensed TrueImage from Apple:
