Rumor has it that PCL-5 not only includes scalable fonts but
rudimentary graphics commands, such as move and draw.
Can someone send me the format of these commands?
How about a gnuplot driver?
Thanks,

Ahem. PCL-5 contains the complete kernel and dual context extension of the vector-oriented graphics language, HP-GL/2. Far from rudimentary, it includes the ability to fill arbitrary polygons (concave, with islands, self intersecting - whatever) with both hatch and raster (and user-defined raster) fills with specifiable anchor corner. There are commands to set line thickness, type of line cap and join, miter limit, linetype, user-defined linetype. There are built-in arcs and circles, wedges and rectangles. There are many text attributes to control labelling in addition to the fonts, giving you just about everything except PostScript's ability to label along an arbitrary curve (nice for fancy DTP effects, but not usually needed by most applications I've seen). The reference book is available at technical bookstores (and some large general-purpose bookstores as well): The HP-GL/2 Reference Guide: a Handbook for Program Developers Addison-Wesley Publishing Co./Hewlett-Packard Press ISBN 0-201-56308-8 You can also find documentation on command formats in the LaserJet III Technical Reference Manual Hewlett-Packard part# 33449-90903 As far as a GnuPlot driver, I think you're probably on your own, but I will forward a copy of this post to the project manager in charge of driver connectivity.

PCL 5 includes full HPGL graphics capability as on plotters. Refer to the "PCL 5 Printer Language Technical Reference Manual" (part# 33459-90903) for details of how to use it. For a copy try the sales office at:- Hewlett Packard Company 5161 Lankershim Blvd North Hollywood, CA 91601 (818) 505-5600

PCL5 includes the plotter language, HP-GL/2. You use it something like this,
printf("\33%0B"); // Enter HP-GL/2 mode
printf("IN"); // Initialize HP-GL/2 Mode
.
. // Drawing commands
.
printf("\33%0A"); // Return to PCL
printf("\33E"); // Reset and end job.
There are far too many drawing commands to describe here. But if you were
to insert the following two statements into the code above, you'd draw a
triangle,
printf("SP1PA10,10"); // Select pen 1, move to 10,10
printf("PD2500,10,10,1500,10,10;"); // Pen down and draw three lines.
The complete language for the LaserJet III printers is documented in the
"PCL5 Printer Language Technical Reference Manual", HP Part 33459-90903.
I adapted the example above from this guide.
