Printing a Bitmap

[James GrahamEagle]

I am having trouble printing a bitmap. The code below works
with my Epson 1500 Laser, gives a black & white copy of the
(color) bitmap on a color postscript printer and garbage on
an HP 712C. Can anybody help?

In the code, all variables a long
pdc = printer device context (no error getting this)
hbm = handle of bitmap

GetObject hbm, SIZEOF(bm), bm
bmx = bm.bmWidth
bmy = bm.bmHeight
hdc = GetDC(Hwnd)
mdc = CreateCompatibleDC(hdc)
SelectObject mdc, hbm
pdcmem = CreateCompatibleDC(pdc)
pbm = CreateCompatibleBitmap(pdc, bmx, bmy)
SelectObject pdcmem, pbm
BitBlt pdcmem, 0, 0, bmx, bmy, mdc, 0, 0, %SRCCOPY
BitBlt pdc, 0, 0, bmx, bmy, pdcmem, 0, 0, bmx, bmy, %SRCCOPY

Now delete objects etc ...

There is an excellent example of printing a color BMP by Don Dickinson in the FILES area of the PB web site... www.powerbasic.com/files/pub

You should look at the sample that I posted (see lance's message).
The reason that your code doesn't work is that BitBlt doesn't work on a bunch or printers. It will work on some. If you're printing a monochrome bitmap it should work on almost all. But for color you really should use DIBs.
