So, you mean a "100 100 moveto" will really cause the plotter's arm to
move immediately? That sound terrible and definite non-optimal for a
sequence like: "100{2{rand 600 mod}repeat moveto}bind repeat 72 72
moveto"!

And a "fill" operator will cause the plotter to lay ink on the paper
immediately?

No, but if it is a level 1 or level 2 printer you might try typing
copypage.

Wow! It works! Although the reponse comes 1--2 seconds later.
Thanks! :D

I've tried it on the HP printers in my lab. It's not that
interactive. After the telnet session is opened, I can type in PS
code. But I get completely no feedback, until I signal the end of
data transmission with a Ctrl-D. Then, all the feedback come at once.
And after that, I can issue no more commands. :(

The executive command, at least according to the red book, is supposed to
start the interactive mode. Did you try that?

It might depend on which printer is used. Some have Adobe PostScript, and
some have a clone.

A parallel port printer connected to an HPNP print server is also not so
likely to do it.

That's correct.
Most postscript printers will run in interactive mode using the executive
command.
