After using the VCL for a while, you get familure with
working with a TCanvas and the TPrinter has a TCanvas so
printing uses the same functions that one would use draw text
on a control or a graph in a bitmap. It also has functions
that draw shapes and lines and copies blocks of pixels from
one Canvas to another. Once the Canvas is set, you print it by
using NewPage or EndDoc.

See, the thing that got me starting this thread was a test
that I did. I generated a bitmap that had text and a pic and
printed that using TPrinter::Canvas. When I put the litteral
text into WordPad and added the pic, it printed slower than
the Canvas test.

Without the pic, they print about the same so I'm assuming
that WordPad could be better optimized when printing graphics
(and that bandwith has nothing to do with it). So ... if one
print method can be faster than another, then why can't there
be another, faster method and how do I know when I've maxed it
out?

And I've read every one with a subject related to printing.

I've got one job that prints proofs for product labeling. That
took quite a bit since the user does nothing but enter text for
variouse sections. I have to select font sizes that maximize
the space on the template and accounts for wordwrap with, with,
with, (can't think of the name for it) the thing that produces
both right and left justified, evenly spaced text.

And then there's different number of labels per sheet, 1up,
2up, 4up ect.. That's a huge block of code.
