Description Inquiry (ENQ) commands are accepted and answered in remote power
down mode. The printer reactivates if the * button is pressed or a power
up command is received.
Note: If power is lost after the power down command is issued, the printer
remembers it is in power down mode but does not reactivate the
communications link. The * button must be pushed to return the printer to
full operation.
Note: This command is not available in STAR mode.
Remote Printer Reset
Reset in Serial Mode
It is possible to generate a software printer reset in serial mode. The [ENQ] <10>
command requests that the printer reset. (This is not a hardware reset). The reset
completely initializes the hardware and software, but the printer does not recover from a
loss of software control.
Note: If the printer mode was changed by the [ESC] y <2> or <3>
command, a soft reset will not return to the power on default.
The command flow is as follows:
The [ENQ] <10> is acknowledged. During cleanup and initialization, the printer is
placed off-line. Before the printer initializes, it tries to clean up its input buffer
and other internal processes.
The printer‘s software is reinitialized.
The power-cycled flag is set.
The print head is homed and re-calibrated.
The printer goes back on-line.
Reset in Parallel Mode
In parallel mode, driving the INIT signal on the parallel port for 100 milliseconds
generates a software reset. It takes about two seconds for the printer to recover from a
reset. The [ENQ] <10> command has the same effect, but it is not acknowledged.
