[Function]
In expanding bar codes with the current setting using this command, information such as the size of
the generated image and errors is sent to the printer.
Therefore, it is possible to confirm whether printing is possible before actual printing, with this com-
mand.
If there is an error in the bar code expansion, the command is ignored even if the expansion com-
mand ESC GS y P is sent.
Also, if the following errors occur, “Error” information is sent to the printer.
• When an error occurs when generating the bar code by the combination of bar code settings
• When the generated bar code exceeds the printable size.
Transmission format: “y” “I” n1 n2
