I am having a problem with the 98644 serial RS232 line talking to the laserjetII. I am currently using the Plotter in a Cartridge that emulates HPGL on the laserjet, but I cannot specify PLOTTER IS 9,"HPGL" This will work for a HP7475A plotter, but it does not work for the laserjet. If anyone has any experience with this type of problem, please contact me As soon as possible. Thanks /David Dreifus dld@ece-csc.UUCP

The "real" plotters, e.g. 7475, speak a language called HPGL (HP Graphics Language) which is what you specified in your PLOTTER IS... The LaserJet speaks a different language, common to most HP printers, called PCL (Printer Control Language), which I believe is not available to the PLOTTER IS.. call. HPGL is a vector/pen-plotter oriented language. PCL is a text/bitmap oriented language, and the two are very different. LaserJet does not know how to draw a vector; you must create a bitmap containing the vector(s) required, and send that to the LaserJet. You can say PLOTTER IS "somefilename","HPGL" and plot the data to the file "somefilename". There is a third-party utility available from L.W. James and Associates, and possibly from elsewhere as well, that can convert this HPGL "spoolfile" to a bitmap and send it to your LaserJet. HP cannot recommend use of any particular third-party software, nor can we support it.
