When the graphics program is finished, it exits but the creation program remains running with the graphic remaining in the window. This mode can now be used to overlay plots. Secondly, the creation program can create multiple frames, which enables looping. The output device generates postscript output suitable for printing. Essentially, this mode generates a simple postscript file that either can be written to a file or spooled to a print queue.
Output can be either to grayscale printers or to a color postscript device.
This allows for overlay plots much like the window mode. This output device creates HPGL codes that can be routed to plotters that support HPGL and recent HP Laserprinters that support PCL version 5. The output can be written to a file or spooled directly to a print queue. There is no color support. Also, this device can be set up so that output can be appended and printed later with the hpglcat program.
