T480 Programmer's Guide
When printing line graphics, the data path to the printer must be eight bits. Seven-bit
serial protocols do not access the extended characters. The extended characters
require that the form be reverse fed. Consequently, printing line graphics on the receipt
may be less than acceptable.
APA Graphics
The printer is capable of all-points-addressable (APA) or horizontal graphics.
Generating a graphic image by hand is time consuming and tedious. It is recommended
that a graphic package be used to create a graphic image. The following procedure will
help with the setup.
Procedure for APA graphics:
1. Generate the graphic image in the program of your choice. APA graphics only
support monochrome images.
2. Make sure the paper size chosen fits the printer (3 inches wide with 0.25-inch
margins). If the paper size cannot be set, print a portion of the page.
3. Print the graphic to a file using a generic, IBM, graphic, 9-pin driver. The standard
IBM resolutions are 240 x 216 dpi, 120 x 72 dpi, and 60 x 72 dpi. The EPIC 3000
Printer supports all three resolutions. For good resolution with reasonable speed,
use 120 x 72 dpi.
4. Print the graphic image to a file.
5. Edit the resulting file to remove any unwanted form control, and insert the EPIC 3000
form control.
6. Make the resulting file available to your application, so it can be sent to the printer
when required.
Color Graphics
The EPIC 3000 has a two-color option. The EPIC 3000 has a two-color and is not a full
color printer. A full color printer forms the various colors of an image by mixing inks of
different colors on the paper. The amount of each color determines the hue. Typically
the paper is white and no ink produces a white. Mixing yellow and cyan produces a red
and mixing cyan, magenta, and yellow in equal amounts produces a black or gray.
