Thread: Question about fonts and printing

Hi.

I'm working on a program that must print data and to have a printview. My question is: Is there any straight way to create fonts which are at the same size both on the screen and on the printer or I must use the ratio between the values which I get throught this calls:

Code:

int MaxX=GetDeviceCaps(hDC,PHYSICALWIDTH);
int MaxY=GetDeviceCaps(hDC,PHYSICALHEIGHT);

for a printer hDC and a screen hDC?

For fonts, I think you can use the same point size for each device. Converting point size to logical units for a device which can then be passed to CreateFont is performed with the following formula:

nHeight = -MulDiv(PointSize, GetDeviceCaps(hDC, LOGPIXELSY), 72);

For images, your approach is spot on. See this MSDN printing example.
