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 devi ces is expected to rise. At present, however, many of t he 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 S ale).

The aim when developing ESC/POS was to create a set of control codes that could be used to
operate any output device c onnected to a PO S terminal. T hese new codes ar e 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 produ ce new models in t he TM/DM series offeri ng ESC/POS
support and to continue to work for the standardization of the entire POS environment to
promote the dissemination of ESC/POS.

TM-T88/T88P (TM-T85/T85P) Information Manual

❏ ESC i, ESC u, and ESC v are supported only by TM-T85/T85P.

These commands are not recommended. (There are other commands which support the
same functions of the above commands.) For the TM -T88/T88P, GS V and GS r can be used
as the above commands.

❏ The functions of GS V and ESC c 5 are different for TM-T88/T88P and TM-T85/T85P.
❏ For DLE EOT, GS a and GS r, conditions of status changes for paper roll sensor and

automatic recovery error are different for TM-T88/T88P and TM-T85/T85P.

Using Bit Value Tables

For each command that has a compl ex method o f determi ning the variable n, there is a t able sho wing
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 do uble hei ght , doubl e wid th , and underli ne, d epending
on the numbering system used:

Note that the program examples throughout this chapter use decimal numbers, but binary, decimal,
and hexadecimal numbers all have the same printing results.

Print Commands

The TM-T88/T88P (TM-T85/T85P) supports the following commands for printing characters and
advancing paper. When executing printing with the standard mode selected, the printer executes
paper feed. When the page mode is selected, except for FF and ESC FF, only the data development
position is moved and actual printing and paper feeding are not executed.

Command Name
LF Print and line feed
CR Print and carriage return
ESC J Print and feed paper
ESC d Print and feed n lines
FF Print and return to standard mode (in page mode)
ESC FF Print data in page mode

LF

[Name] Print and line feed
[Format] ASCII LF

Hex 0A

LF prints the data i n the print buffer and feeds one li ne. The amount of paper fed per li ne i s based on
the value set using the line spacing command. The default setting is 1/6 inch.

CR functions in the same way as LF when auto line feed is enabled. Auto line feed can be disabled or
enabled by DIP switch 1-1. This command sets the print position to the beginning of the line. When
auto line feed is disabled, this command is ignored. This command is available only with a parallel
interface an d is ignored with a serial interf ace.

ESC J n prints the data in the print buffer and feeds the pap er n × (vert ical or horizo ntal mot ion uni t).

This command is used to temporarily feed a specific length without changing the line spacing set by
other commands. The maximum paper feed amount is 40 inches. When standard mode is selected,
the vertical motion unit set by GS P is used. When page mode is selected, the vertical or horizontal
motion unit set by GS P is used for the print direction set by ESC T.

ESC d n prints the data in the pr int buffer and feeds n lines. The amount of pap er fed per line is based
on the value set using the line spac ing command. The maximum paper feed amount is 40 i nches. The
default setting of the paper feed amount is 1/6 inch.

FF prints the data in the print bu ffer collectively and returns to standard mode. The buffer data is
deleted after being printe d. This comman d returns the values set by ESC W to the default values.
The value set by ESC T is maintained. This command is enabled only in page mode.

ESC FF prints all buffered data in the printable area collectively, in page mode. This command is
enabled only in page mode. After printing, the printer does not clear the buffered data or values set
by other commands. When the printer returns to standard mode, FF or ESC S should be executed.
The above commands do not cut the paper.

Line Spacing Commands

The TM-T88/T88P (TM-T85/T85 P ) su pports the following comman ds f or setting line spacing. These
commands only set the line spacing; they do not actually advance the paper. The line spacing can be
set independently in standard mode and in page mode. The line spacing set using these commands

ESC 2 sets the line spacing to 1/6 inch. This is equivalent to 30 dots.
ESC 3 n sets the line spacing to n × (vertical or horizontal motion unit). The default setting of the

paper feed amount is 1/6 inch (n=60). The maximum line spacing amount is 40 inches. When
standard mode is selected, the vertical motion unit set by GS P is used. When page mode is selected,
the vertical or horizontal motion unit set by GS P is used for the print direction set by ESC T.

The line spacing can be set independently in standard mode and in page mode.

Rev. A Command Descriptions 1-9

ESC & y c1 c2 [x1 d1 ... d(y × x1)] ... [xk d1 ... d(y × xk)] defines user-defined characters from character
code c1 to c2. y and x are the configuration of a user-defined character. y specifies the number of
bytes in the vertical direction. x specifies the number of dots in the horizontal direction. Character
codes from the alphanumeric characters (20H (decimal 32) to 7EH (decimal 126)) ca n be defined by c1
and c2. Data (d) specifies a bit printed to 1 and not printed to 0. As the default, user-defined
characters are not defined and the internal character set is printed. Once the user-defined characters
have been defined, they are available until ESC ?, ESC @, or GS ✻ is executed; the user-defined
characters are redefined; the power is turned off; or the printer is reset. When this command is
executed, the downloaded bit image is canceled.

ESC ? n cancels the user-defined characters defined for the character code n. After the user-defined
characters are canceled, the internal character set is printed.
