!P 1
means one normal attempt plus one retry. Default is 1, which is the value used if no
digit is present.
EJECT FULLY
Adding an E (
!PE
) makes the printer eject the ticket fully so that it can fall down into a
tray (for FL3 printers)
Digits and @, or digits and E can be mixed on the same line, for example
!P5@
makes
five encoding retries, and ejects the ticket into the wastebasket.

Write transaction string
!Q
writes a string with up to 15 ASCII characters to a non-volatile buffer memory in the
printer.
Example:
!Q asdfgh <CR><LF>
After the ticket has been correctly encoded / printed, the string is copied to a non-volatile
buffer. This buffer can be read by the !V-command.
The transaction string is committed at the precise point where a useable ticket has been
produced. The only way to reset a transaction string is to successfully print another
useable ticket that was initiated with
!Q
.
