•
Sufficient blank space on either side of the bar code must be left to create a quiet
zone.
•
A good ratio/element size must be selected if the default values are not being
used.
•
Adequate room must be available for the bar code to be printed on the ticket.
•
Bar codes may only be printed in black, for accurate infrared scanning, using
thermal media with a visible light absorption of 600-700 nm for black printing.
A bar code object is self-terminating and will be processed as soon as the proper
amount of data has been sent to it. The print bar code command’s (
GS k ) second
parameter specifies whether a fixed amount of data will be sent or whether delimiters will
be used. In either case, the data sent must match the parameter setting. If a fixed
number of characters are specified, then the exact number of characters specified must
be sent. If delimiters are indicated, then matching characters must be sent before and
after the bar code data to specify the beginning and end of the data. If an incorrect
number of characters or delimiters are sent, the Epic Edge™ will not print correctly.
Bar codes that are too long to fit within the printable area of a ticket are truncated. This
usually results in an unreadable bar code being printed. To correct this condition, a
narrower ratio must be set, fewer digits encoded, or a more compact symbology used.

Graphic Objects
Graphic objects are created by the landscape printing mode graphics command ( GS * ).
Graphic objects may only be printed as part of a landscape page. To print a graphic
without entering landscape printing mode, you must use bitmap graphics mode.
No landscape graphic may be wider than 256 dots, though they may be as tall as the
width of the Epic Edge™’ print head. If a graphic needs to be printed wider than 256
dots, either subdivide it into narrower sections or print it using bitmap graphics
commands.
