What are the contact-printers mentioned in Kodak publication G10 for the discontinued Azo papers and where can I buy one? I have copied and pasted some of this below.

Contact printers generally have a very high level of
illumination. In order to keep exposure times within reason,
contact printing papers, such as AZO Paper, are made with a
relatively low speed. Therefore, itís not practical to use
contact papers with an enlarger as a light source.
A contact printer is a glass-top box with exposing lights
and a safelight inside, and hinged pressure cover over the
glass. Switches control the lights that allow different
intensities to various parts of the image.
