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–U375/U375P 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.
Bit Off/On Hex Decimal Function
0Off 00 0 Character font 5 x 9 selected.
On 01 1 Character font 7 x 9 selected.
1, 2 — — — Undefined.
3Off 00 0 Emphasized mode not selected.
On 08 8 Emphasized mode selected.
4Off 00 0 Double-height mode not selected.
On 10 16 Double-height mode selected.
5Off 00 0 Double-width mode not selected.
On 20 32 Double-width mode selected.
6 — — — Undefined.
7Off 00 0 Underline mode not selected.
On 80 128 Underline mode selected.

The TM-U375/U375P supports the following commands for printing characters and advancing
paper:
Command Name
LF Print and line feed
CR Print and carriage return
FF Print and eject cut sheet (in standard mode)
Print and return to standard mode (in page mode)
ESC J Print and feed paper
ESC d Print and feed nlines
LF
[Name] Print and line feed
[Format] ASCII LF
Hex 0A
Decimal 10
LF prints the data in the print buffer and feeds one line. The amount of paper fed per line is based on
the value set using the line spacing command. The default setting is 1/6 inch.
CR
[Name] Print and carriage return
[Format] ASCII CR
Hex 0D
Decimal 13
CR prints one line of data from the print buffer and does not feed the paper. This command sets the
print starting position to the beginning of the line.
Program Example Print Sample
PRINT #1, "AAAAA"; CHR$(&HA); AAAAA
PRINT #1, "BBBBB"; CHR$(&HA); BBBBB

FF
[Name] Print and eject cut sheet (in standard mode)
Print and return to standard mode (in page mode)
[Format] ASCII FF
Hex 0C
Decimal 12
In standard mode, FF prints the data in the print buffer and ejects the cut sheet (slip or validation
paper). This command is enabled only when a cut sheet is selected for printing. When the eject
length has been set by ESC C, the printer ejects the cut sheet based on the current eject length
regardless of the cut-sheet paper sensor state. Otherwise, the printer ejects the cut sheet completely.
Paper from the paper roll is not ejected, even if it is also selected.
After cut-sheet ejection, the paper roll is selected for printing. The cut sheet is ejected in the forward
direction only.
In page mode, FF prints the data in the print buffer collectively and returns to standard mode. The
buffer data is deleted after being printed, but the paper is not ejected.
Program Example <standard mode> Print Sample <standard mode>
PRINT #1, CHR$(&H1B);"c0";CHR$(4);← Select slip
PRINT #1, "AAAAA"; CHR$(&HA);
PRINT #1, "BBBBB"; CHR$(&HC);

ESC % n selects or cancels the user-defined character set. When the LSB (least significant bit) of nis 1,
the user-defined character set is selected. When it is 0, the internal character set is selected; this is the
default setting.
ESC & y c1 c2 [x1 d1 ... d(y ×x1)] ... [xk d1 ... d(y ×xk)] defines user-defined characters from character
code c1 to c2. yand xare the configuration of a user-defined character. yspecifies the number of
bytes in the vertical direction. xspecifies the number of dots in the horizontal direction. Character
codes from the alphanumeric characters (20H (decimal 32) to 7EH (decimal 126)) can 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.
