Range: m = 0
(n

Description: Sets the resettable maintenance counter specified by n
L
and n
H
to 0.
• n
L
and n
H
specify a resettable maintenance counter number as (n

256).
In addition, the associated change counter (if existing) is increased by one.
This is only possible by n
L
+ n
H
x 256 = 20, 21 and 50.
Example: If the Cutter is replaced and GS g 0 0 50 00 is executed, the cutter
change counter CUTC is increased by one (command GS g 2 see page 166).

Notes:
• In standard mode, this command is effective only when processed at the
beginning of a line.
• Unsupported counter numbers cannot be specified.
• Do not use this command while a macro is being defined, because the
command cannot be included in the macro.
• There are two kinds of maintenance counters: resettable counters and
accumulation counters. A resettable counter is a maintenance counter
that can be initialized, and an accumulation counter indicates the counter
value from when the printer starts operation. An accumulation counter
cannot be initialized (see GS g 2 for details of the accumulation counter.)
• Take the following into account when writing data to a non-volatile
memory.
• The printer may be in BUSY state when processing this command. In this
case, be sure not to send a command from the host to the printer,
because the printer will not receive the command.
