Printing Images

Printing with ImageMan is just as simple as using ImageMan to display images. Although it might seem that the ImgDrawImage function could be used for printing just as easily as for displaying, the ImgPrintImage function does exist for some specific reasons. Most notably, ImgPrintImage is optimized for banding output, and will always produce the highest quality image possible in the fastest time. ImgPrintImage also affects the printing of Encapsulated Postscript (EPS) images; since EPS images usually contain an embedded TIFF image for display purposes, using ImgDrawImage to output an EPS image will result in the TIFF image being printed instead of the much higher-quality EPS image. For these reasons, is it recommended (but not required) that you use ImgPrintImage for all printer output.

Whenever you print color images from a Windows program, it is important to note the differences between printers that you may encounter. Specifically, some printer drivers (like the HP LaserJet driver and the PostScript driver) will produce much higher-quality color images through the use of dithering or halftoning algorithms to simulate grayscale (this is assuming, of course, that you're not using a color PostScript device.)
