🚀 go-pugleaf

I cannot get the cartridge to change back to PostScript mode after it
has been switched into PCL mode.  I have even tried connecting a
terminal directly to the printer.  I can type in the commands to go
to PCL mode without difficulty:

    serverdict begin 0 exitserver
    statusdict begin 1 setsoftwareiomode
    end

and it will change to PCL mode.  But, when I type in the escape sequence
to get back to PostScript:

    Esc Delete 0 Control-D

nothing happens.  If I type a formfeed after this, the printer will print
a graphic character on the page ejected.

Any ideas?
