There are two types 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.)
■
Featuring counters differ, depending on the printer model. See
GS g 2
for details.
■
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.
•
Excessive use of this function may destroy the non-volatile memory. As a guideline, do not use any
combination of the following commands more than 10 times per day for writing data to the non-
volatile memory:
FS q, GS ( A
(part of functions),
GS ( C
(part of functions)
, GS ( E
(part of
functions)
, GS ( L / GS 8 L
(part of functions)
, GS ( M
(part of functions)
, GS g 0
, or
FS g 1
.
■
The maintenance counter value can be transmitted by
GS g 2
.
■
Note the rules below for the operating NV memory (store data / cancel data):
•
Paper feeding is disabled by the paper feed button.
•
The printer does not process real-time commands.
•
Even if “ASB is enabled” is specified, the printer does not send ASB status.
■
The maintenance counter value can be used for establishing the time for replacing consumed parts or
cleaning.
■
Types of counters differ, depending on the printer models (see the model-dependent information of
GS g 2
).
[Model-dependent variations]
None
Program Example
PRINT #1, CHR$(&H1D);”g0”;CHR$(0);CHR$(11);CHR$(0);
