Bar Codes
The EPIC 3000 Printer supports the ability to print bar codes. The printer offers a
number of formats as defined below. The host does not need to form the graphic image
for these bar codes. The host need only send the printer the information to be bar coded
and a graphic is generated by the printer. In some cases, a check character is required
by the format. In most cases, the printer generates the check character and inserts it
correctly in the format. The printer uses internal graphic modes to form bar code images,
and the images are adjusted for ink bleed. In general, the bar codes generated by
sending graphic data to the printer are not as readable as the bar codes the printer
generates. Bar codes are printed at a 203 x 203 resolution.
Barcodes may be printed horizontally or vertically (using page mode).
