1 Overview

This manual classifies the printer commands into several kinds based on its functions, and also

describes the applications of relative commands in detail depending on its sorts. We hope that it is

helpful for programmers to get known of those commands.

1.1 Commands classification

This receipt printer commands are classified as below:

Print commands: used for printing and feeding paper;

Position commands: to control the print position;

Character commands: to set character property;

Bitmap commands: to download bitmap and print, including NV and RAM bitmap;

Status commands: used for printer status query;

Barcode commands: barcode print and property settings;

Bi-color commands: bi-color print and property settings.

Upside-down print command: upside-down print and property settings.

Watermark printing command: watermark print and property settings.

Greyscale printing command: greyscale print and property settings.

Control command: choose paper-saving mode and reduce ticket width.

Double-side relevant command: relevant print and property settings of double-side print mode.

Other commands: used for periphery control, Macro-definition and initialization;

Command instruction refers to the detailed function of relative commands.

1.2 Key terms

Real-time commands –These commands are acted on immediately upon being received by the

printer;

Print buffers –Used to store figure data to be printed;

Page mode –Under this mode, the printer stores all data in a specified memory and thinks of this as a

virtual page. The page is printed when the printer receives print command either FF or ESC FF;

Standard mode –Standard mode is the default mode of printer, namely line mode. Under this mode,

the printer prints data and feeds paper upon print line buffer full (data is enough for one print line) or

receiving print command like LF;

HRI character –Barcode note character. Human Readable Interface;

NV –Non-volatile memory in which data stored does not loss when powered off. NV: Non-volatile;

RAM –Random Access Memory;

DPI –Print dots per inch (one inch equals to 25.4mm). It is used to identify the resolution of a printer.

Example, 203DPI means 203 print dots per inch. DPI: Dot Per Inch

Baseline –The standard position where character data in print buffers are stored. The figure shows the

position of ordinary characters in standard mode and page mode:

The paper feed amount set by this command is not affected by the values set by ESC 2 or

ESC 3.

The horizontal and vertical motion unit is specified by GS P.

In standard mode, the printer uses the vertical motion unit (y).

In page mode, this command functions as follows, depending on the starting position of

the printable area:

1) When the starting position is set to the upper left or lower right of the printable area

by ESC T, the vertical motion unit (y) is used.

2) When the starting position is set to the upper right or lower left of the print able area

by ESC T, the horizontal motion unit (x) is used.

The maximum paper feed amount is 1016mm (40 inches). When the setting value

exceeds the maximum, it is converted to the maximum automatically.

[Notes] • 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 sets the printing

position to [Print area width + 1].

• Horizontal tab positions are set with ESC D.

• If this command is received when the printing position is at [print 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.

• The default setting of the horizontal tab position is 8 ASCII characters (12×24).

• When current buffer is full, the printer shall execute the actions as below:

[Notes] • Settings outside the specified printable area are ignored.

•The horizontal and vertical motion units are specified by GS P.

•In standard mode, the horizontal motion unit (x) is used.

• In page mode, horizontal or vertical motion unit differs depending on the starting position

of the printable area as follows:

1) When the starting position is set to the upper left or lower right of the printable area

by ESC T, the horizontal motion unit (x) is used.

2) When the starting position is set to the upper right or lower left of the printable area

using ESC T, the vertical motion unit (y) is used.

BTP-R980 Programming Manuall

- 7 -

[Range] 1 ≤ n ≤ 255

0 ≤ k ≤ 32

[Notes] • The horizontal tab position is stored as a value of [character width ×n] measured from

the beginning of the line. The character width includes the right-side character spacing,

and double-width characters are set with twice the width of normal characters.

• This command cancels the previous horizontal tab settings.

• When setting n = 8, the print position is moved to column 9 by sending HT.

• Up to 32 tab positions (k = 32) can be set. Data exceeding 32 tab positions is processed

as normal data.

• Transmit [n] k in ascending order and place a NUL code 0 at the end.

• When [n] k is less than or equal to the preceding value [n] k-1, tab setting is finished and

the following data is processed as normal data.

• ESC D NUL cancels all horizontal tab positions settings.

• The previously specified horizontal tab positions do not change, even if the character

width changes.

• The character width is memorized for each standard and page mode.

[Default] The default tab positions are at intervals of 8 characters (columns 9, 17, 25...) for font A

(12 ×24).

[Range] 0 ≤ xL, xH, yL, yH, dxL, dxH, dyL, dyH ≤ 255 (except dxL= dxH=0 or dyL= dyH=0)

[Notes] • If this command is input in standard mode, the printer executes only internal flag

operation. This command does not affect printing in standard mode.

•If the horizontal or vertical starting position is set outside the printable area, the printer

stops command processing and processes the following data as normal data.

• If the printing area width or height is set to 0, the printer stops command processing and

processes the following data as normal data.

•This command sets the position where data is buffered to the position specified by ESC

Twithin the printing area.

•If (horizontal starting position + printing area width) exceeds the printable area, the

printing area width is automatically set to (horizontal printable area －horizontal

starting position).

•If (vertical starting position + printing area height) exceeds the printable area, the printing

area height is automatically set to (vertical printable area –vertical starting position).

•The horizontal and vertical motion units are specified by GS P. Changing the horizontal

•Use the horizontal motion unit (x) for setting the horizontal starting position and printing

area width, and use the vertical motion unit ( y) for setting the vertical starting position

and printing area height.

•When the horizontal starting position, vertical starting position, printing area width, and

printing area height are defined as X, Y, Dx, and Dy respectively, the printing area is set

as shown in the figure below.

• When pitch N is specified to the right: nL+ nH ×256 = N

• When pitch N is specified to the left (the negative direction), use the complement of

65536.

• When pitch N is specified to the left: nL+ nH ×256 = 65536 - N

• The print starting position moves from the current position to [N ×horizontal or vertical

motion unit]

•The horizontal and vertical motion units are specified by GS P.

•In standard mode, the horizontal motion unit is used.

•In page mode, the horizontal or vertical motion unit differs as follows, depending on the

direction and starting point of the printing area:

1) When the starting position is set to the upper left or lower right of the printable area

using ESC T, the horizontal motion unit (x) is used.

2) When the starting position is set to the upper right or lower left of the printable area

using ESC T, the vertical motion unit (y) is used.
