Print Modes

The Epic Edge™ supports three modes of printing: bitmap graphics mode, portrait
printing mode, and landscape printing mode. Each mode operates under very different
rules. These rules are detailed below.
Note: The Epic Edge™ Printer may be in only one print mode at a time. Multiple areas
may be printed in different print modes on a single ticket, but these areas may only be
adjacent to one another, they may not overlap.

Bitmap Graphics Mode

At its most basic level, the Epic Edge™ Printer is a direct thermal printer that creates
images on a ticket by heating the individual elements of its print head. The print head
has 712 elements (or dots). When it prints, some of these dots will be turned on
(heated), and the printer's motor will advance the ticket by a step. The ticket stock that is
under a heated element will then turn black. For each motor step, a dot line is printed in
300 x 300 dpi resolution. Each dot line is a complete object and is printed by the Epic
Edge™ as soon as it is processed. Because of this, a bitmap dot line should not be sent
while a portrait object or a landscape page is being constructed.

Portrait Printing Mode

On power-up, the Epic Edge™ Printer is set for portrait printing. In portrait printing mode,
text characters exit the printer from the top of the character to the bottom. It is also
possible to switch to this mode using the set print orientation command (GS V).
Portrait printing mode is also referred to as immediate mode printing, because each
object that is sent to the printer while the printer is in portrait printing mode is printed as
soon as the object is completed. No two objects may be printed on the same line in this
mode because the ticket is advanced as each object is completed and printed.
Certain commands are disabled or work differently while the Epic Edge™ is in portrait
printing mode. Exact details can be found under each command's description.
