Paper roll Bar code commands GS k
Ver. 10.05 p. 342
■ When page mode is selected, this command develops the bar code data in the print buffer but the printer
does not print the bar code data.
■ The bar code width that exceeds the print area cannot be specified.
■ This command feeds as much paper as is required to print the bar code, regardless of the line spacing
specified by line space setting commands.
■ 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 78.
■ 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]
■ Some models do not support settings of 6, 7, or 8 bytes for the amounts of data to process. For details,
refer to [Model Information].
