I found out that the engraver is made by Universal Lasers for new Hermes. I posted a quick support question on their website and was pleasantly surprised by a prompt email reply back. I now have a manual, firmware update and drivers for winxp and win7!
Applying the update was troublesome. The engraver would not load a file and the print spooler would show a failure just like all the other times I tried to print. Nothing showed up on the engraver screen. I got frustrated and restarted the engraver. When it came back on, I noticed the firmware update had loaded. I didn't get a confirmation on the comp but I took a chance and ran the firmware job on the engraver. It worked! Now the engraver works perfectly with all the stuff I try to print!
Thank you Universal Laser for keeping an 11 year old machine up to date and for helping us out free of charge!
