Label Length
The ^LL (Label Length) instruction defines the length of the label.
This instruction is necessary when using continuous media (i.e. media
not divided into separate labels by gaps, spaces, notches, slots or
holes).
To affect the current label, and/or be compatible with existing print-
ers, this instruction must come before the first ^FS instruction. Once
you have issued an ^LL command, the setting is retained until you
turn off the printer or send a new ^LL instruction to the printer.
