Cut'n'paste from 
http://whatis.techtarget.com/definition/0,,sid9_gci212871,00.html because 
I'm laughing so hard at what your printer is trying to do to you that I 
can't type straight.

Raster graphics are digital images created or captured (for example, by 
scanning in a photo) as a set of samples of a given space. A raster is a 
grid of x and y coordinates on a display space. (And for three-dimensional 
images, a z coordinate.) A raster image file identifies which of these 
coordinates to illuminate in monochrome or color values. The raster file is 
sometimes referred to as a bitmap because it contains information that is 
directly mapped to the display grid.

A raster file is usually larger than a vector graphics image file. A raster 
file is usually difficult to modify without loss of information, although 
there are software tools that can convert a raster file into a vector file 
for refinement and changes. Examples of raster image file types are: BMP, 
TIFF, GIF, and JPEG files. </quote>

If a printer had tried to charge me for that, he'd be short one client.
