Bar codes
These commands format and print bar codes and are described in order of their hexadecimal codes.
Select printing position of HRI characters
ASCII GS H n
Hexadecimal 1D 48 n
Decimal 29 72 n
Value of n: Printing position
0 = Not printed
1 = Above the bar code
2 = Below the bar code
3 = Both above and below the bar code
Default: 0 (Not printed)
Prints HRI (human readable interface) characters above or below the bar code.
Select pitch of HRI characters
ASCII GS f n
Hexadecimal 1D 66 n
Decimal 29 102 n
Value of n: 0 = Standard pitch at 15.2 CPI
1 = Compressed pitch at 19 CPI
Default: 0 (Not printed)
Selects standard and compressed font for printing bar code characters.
When slip is selected as the interface, HRI is always compressed.
Select bar code height
ASCII GS h n
Hexadecimal 1D 68 n
Decimal 29 104 n
Value of n: Number of dots
Range of n: 1–255 (decimal) 01-FF (hexadecimal)
Default: 162 (decimal) A2 (hexadecimal)
Sets the bar code height to (n/154”) for receipt and (n/172”) for slip.
Print bar code
First Variation Second Variation
ASCII GS k m d1…dk NUL GS k m n d1…dn
Hexadecimal 1D 6B m d1…dk 00 1D 6B m n d1…dn
Decimal 29 107 m d1 dk 0 29 107 m n d1…dn
(0 = End of command)
Selects the bar code type and prints a bar code for the ASCII characters entered. If the width of the bar code exceeds
one line, the bar code is not printed.
There are two variations to this command. The first variation uses a NUL character to terminate the string; the second
uses a length byte at the beginning of the string.
The check digit is calculated for UPC and JAN (EAN) codes if it is not sent from the host computer.
Six-character zero-suppressed UPC-E tags are generated from full 11 or 12 characters sent from the host computer
according to standard UPC-E rules. Start/stop characters are added for code 39 if they are not included.
