Hi
I am using the gobal TPrinter* to print a bit map image. When I use my
HP Office Jet color printer it works fine. When I try to print the bit map
image with a HP Designjet 500 plotter and another plotter I don't have the
model off hand, I get a memory error. is there a known problem with
plotters.
 

Hi William,
What code are you using to print the bitmap? Before troubleshooting
other areas, you should first make sure that you're using a DIB and
StretchDIBits(); see...
graphicsbb.itgo.com/BitmapPrint.html
www.code4sale.com/joehecht/prndib.htm
I've never printed to a plotter before, but you might have to use
banding (i.e., printing the image a strip at a time) to work around the
memory issues.
Good luck,

Here is the code
if (x1/y1>x2/y2) {
// Use Page Width to size the rectangle
MapWindowRect1 = Rect(200, 200, x2 + 200, x2 * y1 / x1 + 200);
} else {
// Use Page Height to size the rectangle
MapWindowRect1 = Rect(200, 200, y2 * x1 / y1 + 200, y2 + 200);
}
Prntr->BeginDoc();
Prntr->Canvas->StretchDraw(MapWindowRect1, MergedBitmap);
Prntr->EndDoc();

William,
You'll want to use the StretchDIBits() GDI function instead of the
StretchDraw() method. See if the code on the first link I provided
performs any better.
HTH,
