■The bar code is not affected by print mode (emphasized, underline, or 90° clockwise-rotated), except for
upside-down print mode.
■After bar code printing, the print position moves to the left end of the print area. The printer enters the
status of print position at the head of a line or no data exists in the print buffer.
■The values of
m
from 0 to 6 in (A) and from 65 to 71 in (B) select the same bar code system, respectively.
The printing results are the same.
■This command specifies
m
= 0 to 6 and ends with a
NUL
code.
■When an odd number of data is processed for ITF bar code system (
m
= 5), the printer ignores the last
received data.
■The printer processes
n
bytes from the next data as bar code data by this command specifying
m
= 65 to 71.
■Print area does not include quiet zone (left/right margin) of bar code. Make sure to secure the quiet zone,
using this command.
[Notes for UPC-A (
m
= 0, 65) process]
■Modular check character (1 character) is processed as follows:
• Automatically added when processing data is 11 byte.
• The 12th byte data is processed as a modular check character when processing data is 12 byte. In this
case, modular check character is not checked.
■Left guard bar/center bar/right guard bar are added automatically.
[Notes for UPC-E (
m
= 66) process]
■The first data (
d1
) is processed as number system character (NSC) so 0 must be specified.
■If
n
is out of the specified range or if
n
is an odd number when ITF bar code system (
m
= 70) is selected,
this command is canceled and the following data is processed as normal data.
■Modular check character (1 character) is processed as follows:
• Automatically added when processing data is 11 byte.
• The 12th byte data is processed as a modular check character when processing data is 12 byte. In this
case, modular check character is not checked.
