Note: You may print barcodes in page mode. If you rotate these barcodes 90° or
180° you can get significantly longer barcodes.
Interleaved 2 of 5
Interleaved 2 of 5 is a high-density, self-checking, continuous, numeric bar code. It is
mainly used where fixed-length numeric fields are required. The data field must be an
even number of characters. If an odd data field is sent to the Epic 880TM printer, it will
be zero padded. Due to space limitations, only 16 characters can be printed.
Code 39
Code 39 is an alphanumeric bar code. It is a discrete, self-checking, variable-length
code. The printer prints the complete data field. The number of characters that can be
printed depends on the bar width scaling. If the bar code scale is set to 2, 17
characters may be printed per line. There are two modes of operation for the Code 39
barcodes. The first is in a variable length format. In this mode all characters sent to
the printer will be printed up to the termination character. Only 0-9, A-Z -, period, and
space may be printed. $, %, +, and / Characters may be used as escape characters
for full 128 character support. If illegal characters are passed to the printer, they are
converted to legal codes. (For example, a would be converted to A).
In full 128 character mode, the printer will encode the full 128 character set. In this
mode, the first character received must be the length. IE. [ESC]k<1><n>… where n
specifies the number of characters to follow. The characters following n characters
may be from 0 to 127. Values greater than 127 are converted to printable characters
by removing the 8th bit.
