A number of bytes in the flash PROM hold various parameter values called default
parameters. One or several of them can be overridden temporarily with this command.
See Default Parameter Settings on page 69.
The permanently stored parameters will be used again after a printer-reset command or at
power ON.
The temporary values can, however, be stored in the flash PROM as permanent values with
command <ESC>&<4>.
Set several parameters at once
