SYSVAR, cont.
31: Last control character sent (Read only)
This parameter allows you to read the last control character sent from the
MUSE protocol (special applications).
The printer returns one of the following alternatives:
NUL
ACK
NAK
CAN
32: Odometer value (Read only)
Returns the length of media feed past the printhead (the PD41 odometer
cannot distinguish printheads, so it counts length for the platform).
Resolution: 10 meters.
33: DSR condition on "uart1:" (Read only)
This parameter allows you to read the DSR (Data Send Ready) condition
on the serial channel "uart1:". Not available on the EasyCoder PD41.
The printer returns:
0 = No
1 = Yes
34: TrueType character positioning mode (Set or Read)
This parameter allows you to select one of three modes for the positioning
of TrueType characters and also to read for which mode the printer is set.
The modes are:
0 = Standard mode (default)
This mode was introduced with Intermec Fingerprint 7.2.
1 = Compatible mode
This mode is compatible with Intermec Fingerprint 7.xx earlier than
version 7.2.
2 = Adjusted mode
This mode was introduced with Intermec Fingerprint 7.2.
35: Setup Saving (Set or Read)
This parameter allows you to decide whether a change in the printer’s setup
is to be saved as a file (that is be effective after a reboot or power down) or
not be saved (volatile). You can also read for which alternative the printer is
set. Note that the SYSVAR (35) setting at the moment when the new setup
is entered decides whether it will be saved or not.
The alternatives are:
0 = Setup saved to file (non-volatile) Default
1 = Setup not saved to file (volatile)
