EPIC 630 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. When printed vertically the length of the
barcode can be greater (i.e. more characters can be printed). You can not print human readable
interpretation (HRI) characters in vertical mode. It is generally better to print vertical barcodes by
printing horizontal barcodes in page mode rotated 90
°
or 270
°
. You can then mix HRI and other
text with the barcodes.
