Description

This command provides print suppress and data pass through features.

Where

Bit 0

Printer select

 

Bit 1 Pass through On

Bits 2-7 Undefined

If Bit 0 is clear, the printer will stop processing data. If Bit 1 is set, the data will be passed through the printer and sent out on the serial port.

Notes: The pass through command is processed as part of print data. The pass through command is not processed until it is found in the input buffer by the print processor. It is not an immediate command. The printer must be on-line and ready to activate the command.

The operation of the command can be altered by the print suppress configuration.

Description

This command enables and disables command set features.

 

It is possible that the IPCL commands will interfere with print data. If this is

 

the case, they can be disabled with an [ESC] y <4>.

Notes: Quiet mode operation prints by making two passes for every pass in normal mode. It generates less noise because only half the print wires are activated in each pass. This mode is very slow and should only be used if quiet operation is needed.

ESC y <2> and <3> allow the printer to switch between Normal and EPOS modes. When the switch takes place, the current print buffer is printed and the printer reinitializes. These commands do not permanently change the configuration. A power on reset will restore the mode that was configured in menu mode. A reset by command or from the INIT pin will not restore the mode.

EPOS Note: This command is active in EPOS mode; however, Mode 5 is disabled.
