Format De scription :

The progr amming ma nual c o mmand desc ription include s the fol lowing sectio ns:

1） [Name]

This is the first part o f the command descrip tio ns. AS CII code is g iven co mmand of the fo rm
and the functio n ove rv ie w o f co mma nd .

2） [Format]

This section uses the ASCII coding form, Hex code form, Decimal code form of three kinds of
formal descrip tio n of the command. Which part of the range compared to a decimal number no

special instructions, such as in the following example 1 ≤ n ≤ 4, where 1 is a decimal number,

rather than the ASCII code table in "1".

3） [Range]Gives the allowa ble ranges for the arguments.

4） [Description]Describes the command’s function.

5） [Detail]
The command notice is given. Because commands in different modes, when with different

comma nds, will lea d to mu tu al inf lu ence, a nd this se c tion gives the details.
6） [Reference ]Gives the l is ts o f re lated c o mmands.

HT

] Horizontal tab

[Name
[Format] ASCII HT

[Decription] Moves the print position to the next horizontal tab position.
[Details]

•This command is ignored unless the next horizontal tab position has been set.

• If the next horizontal tab position exceeds the printing area,
the printer setstheprinting position to [Printing area width + 1].

• Horizontal tab positions are set with ESC D.

• If this command is received when the printing position is at [printing area width
+ 1], the printer executes print buffer-full printing of the current line and
horizontal tab processing from the beginning of the next line.

[Details] • When the printer is executing a command to open the cash drawer (ESCp or DELDC4),
the command is ignored.

• In serial mode, the printer immediately after receiving the order.

• In parallel mode, the printer is busy when the command is not executed.

• If the print data same as the command contains data, the data will be used as the command
is executed. The user must take into account this situation.

• Don’t try to insert the command in two or more bytes in the command sequence.

• Even if the printer is set to disabled by the command of ESC = (select peripheral), the
order is still valid.

• The printer can underline all characters, but can not underline the space set by
HT or 90 ° clock wi se r otate d cha r acter s. 

•

The thickness of the underline is that selected by ESC , regardless of the

character size.

• When some characters in a line are double or mor e h ei g ht , al l th e ch a r acter s
on the line are aligned at the baseline.

• ESC E can also turn on or off emphasized mode. However, the setting of the
last received command is effective.

• ESC —can also turn on or off underline mode. However, the setting of the last
received command is effective

•GS ! can also select character size. However, the setting of the last received
command is effective.

• Emphasized mod e is ef f ective for alp h an u me ri c an d Hanzi. All print modes

except emphasized mode is effective only for alphanumeric.

•y specifies the number of bytes in the vertical direction.

• c1 specifies the beginning character code for the definition, and c2 specifies the

final code

• x specifies the number of dots in the horizontal direction.

[Note] • The allowable character code range is from ASCII code <20>H to <7E>H (95characters).

•

It is possible to define multi ple characters for consecutive c haracter cod es .

If o nl y o n e c ha r a ct e r is de sir e d, use c 1 = c 2.

• d is the dot data for the characters. The dot pattern is in the horizontal directionfrom the
left side. Any remaining dots on the right side are blank.

• The data to define a user-defined character is(y×x)bytes.

• A user-defined character and a downloaded bit image cannot be defined
simultaneously. When this command is executed, the downloaded bit image is
cleared.

• The user-defined character definition is cleared when:：

1) ESC @ is executed.

2) ESC ? is executed.

3) ESC? i s exe cute d

4) The printer is reset or the power is turned off.

• When the user-defined characters are defined in font B (9 ╳ 17), only the
mostsignificant bit of the 3rd byte of data in vertical direction is effective.

nL and nH represents the horizontal upper figure points, calculated by nL + nH256 points.

•If the bit-image data input exceeds the number of dots to be printed on a line,the

excess data is ignored.

•d indicates the bit-image data. Set a corresponding bit to 1 to print a dot or to 0to

not print a dot.

•If the width of the printing area set by GS L and GS W less than the widthrequired

by the data sent with the ESC * command, the following will beperformed on the line
in question (but the printin g cannot exceed th e maximump rint abl e area):

①The width of the printing area is extended to the right to accommodate theamount
of data.

②If step ① does not provide sufficient width for the data, the left margin isreduced
to accommodate the data.For each bit in the single density mode (m = 0, 32) of the
data, the printer prints two points: For double density mode (m = 1,33) of each bit of
data, the printer prints a dot . When calculating the amount of data that can be printed
on one line, they must be considered.

• After printing a bit image, the printer returns to normal data processing mode.

• This command is not affected by print modes (emphasized, double-

strike,underline, character size or white/black reverse printing), except upside­downprintin g mode.

• When underline mode id turned off by setting the value of n to 0 or 48,

thefollowing data is not underlined, and the underline thickness set before
themode is turned off does not change. The default underline thickness is
1 dot.

•Changing the character size does not affect the current underline thickness.

• Underline mode can also be turned on or off by using ESC !. Note,

however,that the last received command is effective.
