Print Code 128 Bar Code

Selects and prints the Code 128 bar code.

This command is available only on RS-232C and Parallel printers.

Hex	Decimal	ASCII	Value of n	Value of dn
1D 6B	29 107	GS k	1-255	0-105
49 n dn 73 n dn		I n dn

Since the characters encoded via Code 128 include the NUL (Hex 00) character, a NUL cannot be used to terminate the Code 128 bar code sequence as is done with other bar code sequences. The number of characters to be encoded is variable and is specified by n.

Following n are the data bytes: dn. The printer processes n bytes from the next character data as bar code data.

∙The first data byte must be a Start code: d1 = 103-105.

∙Data bytes past the Start code: d2 = 0-102.

∙The printer provides the Stop code.

If character code d cannot be printed, the printer prints the processed bar code data up to that point and the following data is treated as normal data. If the horizontal size exceeds one line, the printer does not print the excess data.

This command is enabled only when no data is in the print buffer. When data is in the printer buffer, the printer processes the data following ‘GS k I’ as normal data.

Select Width of Bar Code

Sets the bar code width to n dots or n/152 inch (n/6 mm).

Hex	Decimal	ASCII	Value of n	Default
1D 77 n	29 119 n	GS w n	2, 3, 4	3
