Programming

Printing and Encoding Capability Overview

01/06/2009 TTPM3 Installation and Programming Manual P1003642-001

Triggering a Printout

Putting text, graphics, bar and magnetic codes on the ticket as described above only builds an

image of the ticket in the printer memory. To actually print something on a ticket, you must

send a print command:

!P↵

Every received ”!P CR LF” prints one ticket. (If the printer is configured for dual consecutive

entries, you must also send a select document entry command, see Syntax on page 31.)

Command Acknowledgment

Ticket issuing is automatically acknowledged by the TTPM3 by sending an ACK (06h) to the

host computer after a successful read-after-write of the encoded magnetic information.

If no encoding command and data are sent to the TTPM3, the ACK is still sent (read-after-

write verifies that no data is encoded).

Some other commands are also acknowledged; Error Codes and Status Reporting on page 86.

Additional Commands

In addition to the command that specifies the print, there are a number of other commands

used for functions such as:

• Clearing of the TTPM3 buffer

• Selection of document entry

• Decoding of documents

• Generation of status requests

All applicable commands are listed in the following pages. Detailed descriptions of the

software commands are given with syntax explanations as well as commented examples.

Ticket Memory

The TTPM3 printer has 128k of RAM. This memory is used as input buffer and storage for the

ticket image before being printed out. The memory is cleared at power off.

In normal resolution mode, the ticket image is 384x512 pixels for an 86 mm ticket, and

384x656 pixels for a 110mm ticket. In high resolution mode, the ticket image is 384x727

pixels for an 86 mm ticket, and 384x935 pixels for a 110mm ticket.

Note • ACK/NAK must be enabled through parameter n5, see parameter 5 on page 79.

Note • Make sure not to print data outside this area when you use the !F command.

If you do, you write in parts of the memory that are used for other functions in the printer,

and the result is totally unpredictable.
