JB - Disable Top of Form Backup
Purpose: Use this command to disable automatic top of form backup of the
media.
Syntax: JB
Remarks: By default, top of form backup feeds out an extra amount of media
after printing so that the label can be torn or peeled off properly and
then retracts the media so that printing can start at the top of the
label.
Top of form backup cannot be used if the printer has the optional
cutter installed. To disable top of form backup, send an O command
followed by a JB command.
The JB command disables top of form backup. The printer stops
feeding media when the end of the label aligns with the printhead dot
line. Any j command is ignored, although it is stored in memory and
can be enabled again using a JF command.
JF - Enable Top of Form Backup
Purpose: Use this command to enable automatic top of form backup of the
media.
Syntax: JF
Remarks: Top of form backup is used in connection with the j command. The
printer feeds out enough extra media after printing a label so that it
can be torn, peeled, or cut off properly.
By default, top of form is enabled so that is the media is retracted far
enough to begin printing at the top of the next label.
Top of form backup can be disabled by a JB command. Any j
command is ignored and the printer stops feeding when the end of
the label becomes aligned with the printhead dot line.
If the optional cutter is installed on the printer, the JB command
must be preceded by an O command. However, the j command is kept
stored in memory and can be enabled again using a JF command.
Activating the cutter using an OC command has the same effect as
issuing a JF command.
