Error Codes and Status
Reporting
The host computer uses the TTPM2 status reporting to determine if the print cycle has been
completed or not. If not, error codes help determine what went wrong.
Status

written and verified by sending an ”ACK” (06H) to the host. This indicates that the ticket in
almost ready and should just pass the printhead and be outputted to the customer. You can
extend the acknowledge procedure to send acknowledge for other things than magnetic
encoding. See command !CA.
On firmware versions 01660-330 and later, an ”ETX” (03H) is issued when the print cycle is
completed, which is when the ticket leaves the printhead. At this stage you can be reasonably
certain that the ticket has been correctly issued, and you can proceed with the next ticket.
