I am trying to use an HP LaserJet II ( and III's when they arrive ) as a
substitute for a 7475A plotter connected to an HP 9000 model 520.
The LJ II has Pacific Data Products "Plotter in a Cartridge". I understand
the LJ III's will have this HPGL capability built in.
Anyway, when I connect the printer to the computer via the serial port and
run the following program the ON_LINE light on the LJ II flashes twice but
nothing happens. The program does not complete, waiting on the I/O I guess.

10 plotter is 202,"HPGL"
20 plotter 202 is on
30 move 10,80
40 draw 80,80
50 draw 80,10
60 draw 10,10
70 draw 10,80
80 end
( the address is 202 because the printer is on a mux )

The real problem is that there is about 1 ton of code using HP BASIC GRAPHICS
that cannot be rewritten using HPGL and I would like to plot it to the LJ II.
Can this be done using the serial ports or do I need an HPIB<-> serial/parellel
converter ?
I have seen the MicroPrint 45C mentioned. Who makes this and what does it cost ?
Will it work with HP BASIC 4.0 ?
Help !
