Apparently some of these are not stopped by appletalk or the paralell port.
Short of a re-do of the serial port control software in the printer, there
is not much you can do.  This is one of my pet peeves about postscript.
The reason that the hplaserjet emulation works is that it has a special
mode that it uses.  I don't know which printer you have, but in general
it won't work.
