!U
Firmware version query
1
The TTPM2 responds by sending the following string:
TTPM2 Ticket Printer/Encoder Ver X.XX
Where X.XX is the firmware version.
!V
Read transaction string
1
Reads the string stored by !Q from the memory in the printer.
ENQ
Status request, immediate
The TTPM2 responds by sending the same 1 byte response to the host computer as is
sent as byte 1 in response to the !S command. The ENQ command is effected immedi-
ately after receipt, whereas the !S command is effected in sequence when received.
5.2
Document-entry related commands
!E
Eject through rear document entry
This command ejects, through the rear document entry, any document positioned in the
active position for encoding (or after decoding). See page 44 for definition of active/
standby ticket position.
!L1
Select lower rear document entry (dual entry printers only)
Selects lower rear document-entry and feed the leading document, in the consecutive
supply track, to active position. If, in the preceding operation, the upper rear document
entry has been engaged, the document in that entry is retracted from the active position.
NOTE!
— On dual document entry printers, a ”select rear entry” command (!L1, !L2, !L17
or !L18) must precede the print command (!P). An ACK character is returned if the com-
mand was successful.
If no paper is present, the yellow indicator lights up and the printer waits until the operator
inserts new paper stock.
Note that DIP switch no. 6 must be set to ON to enable the ACK/NAK signaling.
