SUMMARY

Prior to Microsoft Windows NT version 4.0, OpenGL applications that needed to print a rendered scene had to render their scene onto a DIB Section and then print that DIB Section. With Windows NT 4.0, OpenGL applications can now render directly to a printer DC provided the printer is backed by a metafile spooler.

The GLPrint sample included in GLPRT.EXE shows how to set up a printer DC, pixel format descriptor, and viewport in order to render an OpenGL scene to a printer.

    MORE INFORMATION
    
 

    
The GLPrint sample renders a lit-cube to the window. From the File menu,
choose Print, and a dialog box appears. When you choose a printer, the
scene prints provided that the all of the following conditions are met:


    • The print spooler is located on a Windows NT 4.0 (or higher) machine.


    • The printer is backed by a metafile spooler.


    • EMF spooling is turned on for the printer. Some printers, such as
   PostScript printers, have EMF spooling turned off by default.

      

    OpenGL graphics are printed in bands in order to conserve memory. Note
that this can significantly increase the time it takes to print your scene.
