PrintFramework

- -This is an overview of the classes and methods used to print documents. -It also demonstrates how to do print previews and invoke the printer -setup dialog. - -

Classes demonstrated here:

Other classes are also demonstrated, but this is the gist of the printer interface -framework in wxPython. - - - - -""" - - -if __name__ == '__main__': - import sys,os - import run - run.main(['', os.path.basename(sys.argv[0])] + sys.argv[1:]) -
