An I/O device which provides photographic outputs for printing galleys, is the Camera printer Automatic typesetter and Radix printer.

Alternatively referred to as an IO device, an input/output device is any hardware used by a human operator or other systems to communicate with a computer. As the name suggests, input/output devices are capable of sending data (output) to a computer and receiving data from a computer (input).

A compact photo printer is a stand-alone inkjet printer designed to produce 4×6 or 2×3 inch prints from digital cameras. It works without the use of a computer. It is also known as a portable photo printer or a snapshot printer.

The linotype machine operator enters text on a 90-character keyboard. The machine assembles matrices, which are molds for the letter forms, in a line. The assembled line is then cast as a single piece, called a slug, of type metal in a process known as hot metal typesetting.

In mathematical numeral systems, the radix or base is the number of unique digits, including the digit zero, used to represent numbers in a positional numeral system. For example, for the decimal system (the most common system in use today) the radix is ten, because it uses the ten digits from 0 through 9.
