A
UTOMATIC CHARACTERS
Generally, check digit, start/stop bars and left/centre/right guard are calculated and added
automatically as needed. Characters added automatically are not included in the table of
valid codes, refer to “Valid character codes” on page 8 . However, for CODABAR and
CODABAR +CHKmod16, they can be selected from a, b, c and d (0x61~0x64). These must
be sent as barcode data and are included in the number of character codes.
C
URSOR START POSITION
In barcode printing, the cursor position at the time the barcode data is sent is at the lower
left point of the leading bar. Since characters of barcode types UPC-A, UPC-E and EAN/JAN-
13 are laid out to the left of the cursor position at start of printing, the cursor position must
first be set taking any print margin into account.
A
CTIVATING BARCODE PRINT MODE
To activate barcode printing mode an escape sequence is sent in the following form:
( s # p # h # v # b # s # T
Six font selection parameters are used: p, h, v, b, s, T. All parameters are sent as indicated
above in a single escape sequence command. Parameters with default values may be
omitted if desired, but the T parameter must always be present to select the barcode type.
Refer to “Default parameter values” on page 12 .
The following table summarises the use of each parameter.
NOTE
In this manual the term refers to the escape character (0x1B).
