Specialized Print Modes; Synchronous Print Mode - Microcom 424M Operator's Manual

Printer Commands
The General Purpose Status byte mode of operation is enabled by Soft Switch
#5, Bit #8. These are the specific commands:
^ABxxxxxxx1^D25 Enable General Purpose Mode
^ABxxxxxxx0^D25 Disable General Purpose Mode
Note that the binary data entry mode is shown in these 2 commands. The
user must set the "xxxxxxx" values to agree with current settings in order to
avoid changing any of the other settings in Soft Switch #5.
Entering General Purpose Status Byte Mode
Sending the "Enable General Purpose Mode" command will set the printer up
to go into General Purpose mode. The printer will NOT go into General
Purpose Mode until a power cycle occurs to cause the data to be stored in
FLASH memory. This command is nonvolatile, so once the General Purpose
Mode is entered the printer will stay in General Purpose Mode thru
subsequent power cycles.
Exiting General Purpose Status Byte Mode
A printer that is in General Purpose Mode will stay in General Purpose mode
thru power cycles until the "Disable General Purpose Mode" command
(^ABxxxxxxx0^D25) is issued. The next power-ON after a "Disable General
Purpose Mode" command will cause the printer to leave General Purpose
Mode.
Note: A default power-ON will also take the printer out of General Purpose Mode.

5.4 Specialized Print Modes

5.4.1

Synchronous Print Mode

This mode allows the printer to be synchronized to external equipment thru an external
PRINT control line. A second input control line ABORT allows a pending print job to be
terminated. Using this mode allows any label, no matter what size to begin printing
IMMEDIATELY using the print input signal. Printing begins 11 microseconds after the rising
edge of the PRINT control line.
Two control signals are required:
1) PRINT input line
2) ABORT input line
Signal logic levels:
The signals are active high and must be between +15Vdc and +24Vdc to be "1".
The signals must drop below +10Vdc to be "0".
To use this mode, follow these steps:
a)
5-24
(connector P17, Pin #2),
(connector P17, Pin #8)
Download a label format to the printer. This format should not
have the normal ^D3 (PRINT command) in the format. If the
^D3 is left in the format, an initial label will be printed
regardless of the special input line settings.
