TTPM2 Installation and Programming Manual
33
By default the TTPM2 attempts to encode three tickets. The desired number of attempts,
as well as the text used to indicate the cancellation, is programmable through a subcom-
mand to the !F command as follows:
!F M <orientation> <xpos> <ypos> <attempts> <height> <width> <font> <”text”>
All parameters must be specified.
The syntax is identical to !F T with the exception of the parameters <”text”> and
<attempts>.
Text
must be a text string. Variables cannot be used with !F M.
Attempts
are the number of tickets the TTPM2 should attempt to encode. If <attempts> is
set to 1, the TTPM2 will make only one attempt (plus the automatic second attempt on
the same ticket) to encode the ticket. If this fails, <text> will be superimposed on the ticket
that is now being printed.
Setting <attempts> = 2 results is one striped ticket (first unsuccessful attempt) and the
superimposed text for the second unsuccessfully attempted ticket and so on.
All parameters in this command are stored in battery backed-up memory and remain in
effect until overwritten.
The following command string produces the tickets illustrated below at 2 unsuccessful
encoding attempts:
/!.#.##.++$'01$
