Media: Another term for substrate. Common inkjet printers generally require media that have special topcoats to achieve proper adhesion and proper drying characteristics.
Modem: A device that transfers computer information across telephone lines. A modem will work with various types of communications software.

Overlaminate: A protective clear film that extends an image's outdoor life and enhances its visual quality.
