PrntScr from Delphi vs MS Paint (which bypasses some thing)
PrntScr from Delphi vs MS Paint (which bypasses some thing)
(OP)
...have a piece of Delphi (6,7,2010) code which does a screen capture to the Windows Clipboard, and prints a single sheet of the screen (1024x768) on any printer.
Problem: takes too long to get started printing vs MS Paint, which prints immediately.
How to achieve same thing in Delphi/PascaL.
Examination of the print queue - if using Delphi/ Windows normal print entry point; then the print queue fills with 50+ MB of data; if using MS Paint then the print queue fills with about 0.6MB. The Delphi program delivers about 0.7MB of data, but Windows blows it up to 50+MB depending on the printer. Applies to Win XP... Win 7.
What gives?.. What does MS Paint bypass, so that we can bypass that too?
Hope somebody can help.
Thank you for all efforts,
RonQ
