Report "I have a Datamax DMX I-4212 Barcode Printer. Computer operating system is Windows XP. I use a third party software package, to produce barcode labels. The company is Argos Software. The printer is set as a LPT parallel printer. When print function is executed, the ready light flashes as though it is printing, but nothing prints. All internal print test work fine, and I am able to print configuartion. I am trying to print on a standard 4 x 6 label"
