About the Author
Michael Sweet is co-owner of Easy Software Products, a small software firm specializing in Internet and
printing technologies. He first started using a computer terminal at the age of 6 and sold his first program
at age 12. Michael's obsession with printing and graphics led him to develop image-printing software for
dot-matrix and later inkjet printers. After graduating with a bachelor's degree in computer science from
the SUNY Institute of Technology in Utica/Rome, he moved to Maryland to pursue a career in real-time
computer graphics for the Navy.
The draw of printing was too much. After a few years working for the Navy, Michael again began writing
printer drivers. After releasing a freeware program called ''topcl," he went on to found Easy Software
Products and develop the highly successful ESP Print software. In 1997, Michael began work on the
Common UNIX Printing System, and in 1999, his company released CUPS under the GNU GPL license and
ESP Print Pro as a commercial product.
Aside from writing printer drivers, Michael is also author or co-author of several books, including the
Serial
Programming Guide for POSIX Operating Systems
and the

OpenGL Superbible.
When he has free time, he
enjoys cycling, photography, playing the trumpet, and travelling with his wife, Sandra.
