1. "Printing/grabbing window contents"
Recently some people were commenting on this subject.
I got how to save your "Print Preview" window to a bitmap with win32dib.
But how can I print the bitmap to my printer from within my Euphoria
Program without exiting
and going onto the Bmp program?

Because the screen and printer have different sized pixels, you will
need to resize your bitmap for printing.
First, calculate the screen bitmap's physical width and height. Use the
GetDeviceCaps API with the LOGPIXELSX and LOGPIXELSY parameters.
Then calculate the number of horizontal and vertical printer pixels
this would need for the same physical size.
Finally, use the StretchBlit routine to copy and resize the screen
bitmap to the printer.

Thank you for your reply.
I will study that but for now what I want know is how to get the BMP
to the Printer in any size.
Do I use something like
setPenPosition( Printer, 0, y )
wPuts( Printer, "myPix.bmp" )
?

atom bmp
bmp = loadBitmapFromFile("myPix.bmp")
copyBlt(Printer, x, y, bmp)
delete(bmp)

Why does that look too easy?
