I am attempting to install a couple of Ithaca PosJet 100 printers. I get install done, but when starting POS, I get an "Warning 920 Failure was detected in the printer opos drivers" Deleted drivers, re-installed. The printers are attached to LPT1, and the cash drawer is in serial with the printer. In other words, the drawer is cabled to the computer and the printer is then cabled to the drawer. Could this be the problem?
