So far we've only tried printing text files, which isn't terribly exciting. Generally any one printer can only print one format of graphics file -- and yet there are dozens of different formats that we would like to print: PostScript, gif, jpeg, and many more. A program named Magicfilter acts as an input filter, much like smbprint does. It doesn't convert the file formats, rather it provides a framework for identifying the type of document you're trying to print, and runs it through an appropriate conversion tool: conversion tools must be installed separately. By far, the most important of these is Ghostscript, which can convert files from Postscript format to the native format of many printers.
