} (or @) Expands the read-after-write operation. If this is successful, the ticket is proc-
essed in accordance with standard routines, that is, it is separated and printed.
If the read-after-write operation is unsuccessful in the programmed number of
attempts, the ticket is transported forwards, and the waste bin of the front load
mechanism is activated (only printers with front load & waste bin option). The
ticket is dropped into a waste bin.
|} ($@) Combining the characters | and } results in normal behavior if the encoding was
successful. If an error occurs then the ticket is transported back to the start position
and NAK + ‘E’ is sent.

START-UP
The TTPM2 is equipped with battery backed-up memory. All print field definitions are re-
tained even when the printer power is switched OFF.
To enable the TTPM2 to synchronize itself to the incoming data after power up, either
after a usual power ON, or after a power failure, the printer has to receive either a !C
command that it will execute, or a !P command that it will ignore.
Using the !C command to initiate the TTPM2 clears all data that has previously been
stored. To avoid having data cleared, the !P command can be used, for example, to retain
document data stored in the TTPM2 prior to a power failure or power OFF.
NOTE!
Please remember that the TTPM2 has to receive either the !C or !P command, or
both, after power up. All other commands and data will be ignored.
