printing in c

[Braun Brelin]

i would like to thank everyone that responded to my question on vga 
programming......
now i have another small question.

i am writing a statistics package that will allow linear regression
and scatterplots...i have lots of documentation to show me how to 
create a graph on the screen...however...nowhere does it tell me
how to transfer this graph to the printer from within the program
(i.e. without using a print screen or some ram resident utility)
i am using turbo c v 1.0 and an ibm pc with an epson printer
i would appreciate any advice i can get on this matter
thank you
