[reportlab-users] Issues related to setting parameters of graphs, lines, and rectangles, and they are not printing correctly

Hi Andy,

I cannot for the life of me think that anything in our code could be

Well, the code that Tim wrote is more or less exactly how I am drawing my
grid (pretty darn exact).  You might just want to try his and save yourself
the hassle!  But before you do - keep reading!


Can you explain exactly how you are "sending it to the printer"?  What is

> the operating system, the print driver and the printer?



I'm on my way out, and would be happy to compile all this information
tomorrow morning, but I think I found the problem.  Apparently, neither
printer I was using (nor any printer I have access to) liked color.pink.  I
don't think it was ReportLab (and I'm sure you have more insight than I),
but the grayscale handling at the printer just mucked everything up (where
muck = some fancy tech lingo I can't think of right now).  As soon as I
changed the grid color from color.pink to color.black - the grid looks
perfect - really makes it look like I know what I am doing (jokes on them!).

I think that this might be falling outside the ReportLab domain, but! might
you have any recommendations for handling color documents to a black/white
printer?  Do some colors print better than others - or is that really a
function of the printer?
