1. Printer GDI driver can't print out bitmap using MS WORD and PAINT
Hello All
My printer only support 1BPP GDI managed monochrome
format.
On win2k platform, Our GDI driver using
EngAssociateSurface(pdev->hsurf, (HDEV)pdev->hdev,
HOOK_COPYBITS|HOOK_STRETCHBLT|HOOK_BITBLT|HOOK_STRETCHBLTRO
P|HOOK_PLGBLT|HOOK_PAINT|HOOK_TRANSPARENTBLT);
and also implement these function by just call
EngCopyBits,EngStretchBlt,EngBitBlt,EngStretchBltRop,
EngPlgBlt,EngPaint,EngTransparentBlt to let GDI engine
work for us.
I have tested my driver and find sth as follow:
Using Imaging application in start->program->accessary-
print out.
Using IE5 ,It hooks into BitBlt ,CopyBits, StretchBlt,
StretchBltRop and can print out something .(because I can
not find one webpage which has BW bitmap on it, So I am
not sure it has printed out BW bitmap in correct way).
Using start->program->accessary->paint , It did not hook
any GDI function ,nothing print out.
using MS WORD , It merely hooks drvEscape and only print
out text ,the bitmap object on the doc was printed out as
void.
in my code, the gdiinfo->ulVersion = 0x500;
Thanks in advance for any help
