It would be helpful to know what graphical toolkit and canvas widget you are using, as this may well be significant. > Any help would be greatly appreciated! My usual approach is actually to generate a PDF document using ReportLab and send that to the printer. Under *nix this is easy - if available, CUPS can handle PDF directly, or you use acroread -toPostScript to generate postscript and send that. Under Windows, I expect you can use COM to call acrobat if there isn't a simpler method. If you're using an existing canvas widget for your drawing, it depends on the canvas widget. Some can be saved to a bitmap, some can save vector data, etc. If you could explain how you're doing your screen drawing, that would help a lot. > Also, is there any way to send a shell command to access some function > of the basic windows operating system such as sort? import os help(os.system) help(os.popen) for more advanced use, COM is an option. > Or to do a DOS directory and send it directly to a file to be accessed > as needed? I'm afraid I just don't understand that. "Do" a DOS directory? If you want to list the contents of a directory, see help(os.listdir) . -- Craig Ringer -- http://mail.python.org/mailman/listinfo/python-list
