User guide

When data exists in the print buffer, the printer processes the data following m as

normal data. After printing bar code, this command sets the print position to the

beginning of the line. This command is not affected by print modes (emphasized,

double-strike, underline, or character size), except for upside-down mode.

[Notes in page mode ]

This command develops bar code data in the print buffer, but does not print it.

After processing bar code data, this command moves the print position to the

right side dot of the bar code. If d is out of the specified range, the printer stops

command processing and processes the following data as normal data. In this

case the data buffer position does not change. If bar code width exceeds the

printing area, the printer does not print the bar code but moves the data buffer

position to the left side out of the printing area.
