Introduction
ESC/POS
The market for store automation equipment is changing rapidly with the widespread
introduction of POS (point of sale) terminals. These terminals are now appearing even in small
retail stores and specialty shops. They occupy a secure position in the range of applications
available for personal computers.
As more personal computers come to be used as POS terminals, the demand for matching
standardized peripheral devices is expected to rise. At present, however, many of the competing
POS terminal printer displays on the market employ mutually incompatible command sets. This
imposes limits on the expandability and range of applications possible with PC-based systems.
There is a need for a new command set designed to provide the expandability and universal
applicability demanded by the market.
To meet this need, Seiko Epson Corporation proposes the adoption of a newly developed
command set to standardize POS terminal peripheral devices: ESC/POS (Epson Standard Code
for Point of Sale).
The aim when developing ESC/POS was to create a set of control codes that could be used to
operate any output device connected to a POS terminal. These new codes are intended to replace
the mutually incompatible command sets previously in use.
TM/DM series models already support ESC/POS, and they have been evaluated highly in the
marketplace.
Seiko Epson Corporation plans to produce new models in the TM/DM series offering ESC/POS
support and to continue to work for the standardization of the entire POS environment to
promote the dissemination of ESC/POS.

TM–U590/U590P Information Manual
Using Bit Value Tables
For each command that has a complex method of determining the variable n, there is a table showing
how to calculate the variable in three numbering systems: binary, hexadecimal, and decimal.
When you look at the table, first find the value of each component of the variable. Then add the
values of the components together to determine the value of the variable n.
For example, here is how you would use the table below, which selects the print mode, to combine
double height, double width, and underline. In the table, you see that bit 4 on (or hex 10 or decimal
16) turns on double height, bit 5 on (or hex 20 or decimal 32) turns on double width, and bit 7 on (or
hex 80 or decimal 128) turns on underline mode.
To combine all three, turn on bits 4, 5, and 7, which is 10110000 in binary. Or you can add the hex
values 10, 20, and 80 for the hex sum of B0, or you can add the decimal values 16, 32, and 128 for the
decimal value of 176.
Therefore, you send the following to turn on double height, double width, and underline, depending
on the numbering system used:
ASCII ESC ! n
Hex 1B 21 B0
Decimal 28 33 176
Note that the program examples throughout this chapter use decimal numbers, but binary, decimal,
and hexadecimal numbers all have the same printing results.
