Question

How to prevent font auto-resizing when printing

Asked by: trilian

I am trying to print using the Canvas methods in Delphi 2006, even though I set the font size to 13 for the titles,the printed results are giant. I am using mm_lometric mapping mode in order to arrange everything on the canvas. Any ideas on how to prevent this auto-size of fonts and make sure that size 13 font is actually size 13 regardless of which printer it is on?

Also, could anyone point me to an information page on the LPtoDP function besides the msdn site, as it really doesn't help me.

could you be more specific as to how and what you are printing ?

are you printing the form itself
or
are you printing using Printer.BeginDoc

this has a sample of printing a image with LpToDp

look in the Tomes of Delphi for more info

As to the what: I am printing the results page for an identification program which consists of text and borders (drawn using the lineto function).

Now for the how:
I am using Printer.BeginDoc, editing the Printer.Canvas (where I set Printer.canvas.font.size := 13), and printing. Once I have made all the changes that I want to the canvas, I finish with printer.EndDoc. The text that prints comes out MUCH larger than 13 point.

I am unaware of a way to print the entire form without having it reformat itself (poorly in my previous experience), is this another option?

I ended up manually setting the map mode to mm_text for the printer.
