Epson 4100 manual Identifying Data Bytes

124 Universal Control Commands

•In Epson and IBM Proprinter XL emulations, the American Standard Code for Information Interchange (ASCII) is used.

•In DEC emulations, American National Standards Institute (ANSI) standards are used.

Aspects of these standards relevant to the emulations contained in the 4100 printer are described in this section.

IDENTIFYING DATA BYTES

Individual data bytes can be identified using one of several number systems. This section describes three number systems in common use:

•Binary

•Decimal

•Hexadecimal

Three number systems are used because each has advantages in specific situations. Some understanding of these number systems is beneficial when working with printers.
