Is CreateCompatibleDC device independent? Why would it act differently for drives

All,

I am creating a memory device context and a bitmap using the following code:

CBitmap bitmap;
CBitmap* pOldBitmap;
CDC dcMemory;
dcMemory.CreateCompatibleDC(Givendc);
bitmap.CreateCompatibleBitmap(Givendc, nWidth, nHeight);
pOldBitmap = dcMemory.SelectObject(&bitmap);

Everything works great. I create the bitmap, draw my object on it and print it. However, the fonts look differnt in adobe pdf versus the edoc printer. How do I make sure the fonts stay the same? How do I create a compatible DC that is driver independent? I thought CreateCompatibleDC was suppose to do that. Can someone help?

DCs are device independent but bitmaps are not.

Look at DIBs (Device Independent Bitmaps)

However you issue is probably more to do with scale/resolution.
