> Is HPGL at all like PCL? HPGL is more like gerber. It's a vector plotting language - pen up, pen down, move here, move there, etc.
PCL is primarily a raster language. Move cursor here, draw text/raster/whatever. Postscript is a combination, more of a generic programming language that happens to have a lot of graphics-oriented primitives. It can do both vector and raster operations. > I'm not very familiar with printer languages other than > Postscript.

I'm guessing it's using a variant of HPGL embedded in a PCL data stream. I.e. a mode switch between languages. The PCL5 spec has commands for this. You can download the PCL5 spec from HP's web site. _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
