Quick reference for bar code control commands
The printer can print bar codes in the HP LaserJet, EPSON FX-850, and IBM Proprinter XL emulation modes.
Print bar codes or expanded characters
Format: ESC i n ... n \
Creates bar codes or expanded characters according to the segment of parameters ‘n ... n’. For more
information about parameters, see the following Definition of Parameters. This command must end with the
‘ \ ’ code (5CH).
Definition of Parameters
This bar code command can have the following parameters in the parameter segment (n ... n). As parameters
are effective within the single command syntax ESC i n ... n \, they do not apply in the bar code commands.
If certain parameters are not given, they take the preset settings. The last parameter must be the bar code
data start (‘b’ or ‘B’) or the expanded character data start (‘l’ or ‘L’). Other parameters can be given in any
sequence. Each parameter can start with a lower-case or upper-case character, for example, ‘t0’ or ‘T0’, ‘s3’
or ‘S3’ and so one.
Bar code mode
This parameter selects the bar code mode as shown above. When n is ‘t5’ or ‘T5’ the bar code mode (EAN
8, EAN 13, or UPC A) varies according to the number of characters in the data.
