7. System Variables
Continued!
Some sensors and other conditions can be read or set by means of
the SYSVAR system variable.
SYSVAR
The following SYSVAR parameters are released for public use:
SYSVAR(1) returns the value of the LSS/BMS receiver.
SYSVAR(8) returns or sets the level of the LSS/BMS emitter.
SYSVAR(12) returns the value of the paper counter (requires
an optional sensor, some printer models only).
SYSVAR(13) returns the value of the ribbon counter (requires
an optional sensor, some printer models only).
SYSVAR(14) returns the number of errors since last power on.
SYSVAR(15) returns the number of errors since the previously
executed SYSVAR(15) instruction.
SYSVAR(16) returns the number of bytes received at the
execution of a STORE or STORE INPUT state-
ment.
SYSVAR(17) returns the number of frames received at the
execution of a STORE or STORE INPUT state-
ment.
SYSVAR(18) returns or sets the verbosity level.
SYSVAR(19) returns or sets the type of error messages trans-
mitted by the printer.
SYSVAR(20) returns 0 if the printer is set up for direct thermal
or 1 if set up for thermal transfer printing.
SYSVAR(21) returns the printhead density in dots/mm.
SYSVAR(22) returns the number of dots in the printhead.
SYSVAR(23) returns 1 if a transfer ribbon is detected, else 0.
SYSVAR(24) returns 1 if a power-up has been performed since
last SYSVAR(24), else 0.
Parameters 1 and 8 can be used to control the LSS/BMS (label stop
sensor or black mark sensor), either automatically as a part of the
program execution, or remotely. They are also useful for setting up
printers with neither a keyboard nor a standard startup program.
However, if the printer either has a keyboard and/or is provided with
Intermec Shell startup program, it is easier to do this in the Setup
Mode.
Parameters 12 and 13 are intended for use with the optional sensor
kit available for some EasyCoder printers.
Parameters 14 and 15 are primarily intended for service purposes.
Parameters 16 and 17 are used in connection with transfer of images
from the host to the printer and are explained in chapter 14.3.
Parameter 18 is used for returning or setting the printer's verbosity
level, i.e. the printer's response to received instructions as explained
in chapter 7.7.
