Hi David,
               sorry for the late response. looks like otmMac* are fine,
atleast I ran it on some data sets and they seem to match.
I would rigorous it on more data sets(font /char combination) when I get
some time.

The code which I wrote wasn't meant to target any specific printer, thats
one of the reason I had to
go for win32 instead of the printer control language directly.

thanks again
vipin
