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 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.
