*1 ANK(Alphabets and number) is available in the Chinese character mode but it is specified by different code

from ANK mode.

*2 GB18030 is available for the Chinese character mode.

3.2.1 Character sizes

ANK mode

Each font is available in full size, compressed size (half width), double width, double height and half width, double height, and quadruple size.

Full size

3.2.2 Character pitches

Pitch refers to the spacing between neighboring characters. When characters are arranged with a fixed pitch, they will be evenly spaced. If characters extend over several lines, they will align in straight rows.

ESC/P Command Reference

Fixed spacing

When characters are arranged with a proportional pitch, the spacing will vary depending on the character. (For example, “W” is wide but “I” is narrow.) As a result, the excess space between characters is eliminated and the text appears more compact.

Variable spacing

If a fixed pitch is applied to a font that is better with a proportional pitch, all characters are given the same width as the widest character in the font.

C I

Fixed spacing

Variable spacing

C I

Variable spacing

This makes it possible to evenly space the characters of a proportional-pitch font without having to change the font. If a proportional pitch is applied to a font that is better with a fixed pitch, all characters are given the same width, appearing the same as with a fixed pitch.

3.3 Print position

The print position is the standard position for printing characters, bitmaps, and barcodes. There is a horizontal print position and vertical print position, which are the reference points for vertical position movement and horizontal position movement.

3.3.1 Characters

When horizontal writing

Characters are arranged with their top edges aligned with the print position. The baseline of each character is the bottom edge of the character, regardless of size, font, etc.

All characters on a single line are printed with a baseline positions that is the same for each character. If a single line consists of characters with different heights, the characters are aligned with the baseline of the tallest character on the line.

Underlines are drawn 4 dots below the baseline position.

When vertical writing

Start position

Print position

Baseline position

When vertical writing, a center of a character is placed onto the middle of the height of a line.

When vertical writing, an underline starts from a print position and a character starts 4dots blow from the underline.

3.3.2 Bitmaps, barcodes and downloaded images

These types of image data are treated in the same way as characters and are printed with the bottom edge of the image aligned with the baseline.

3.3.3 Same line

Characters and images are considered to be on the same line, even if they are separated by tabs. Horizontal movement to the right between characters or images is regarded as being on the same line; however, horizontal movement to the left is regarded as being on separate lines if wrapping occurs.

3. ESC/P Command Limitations

ESC/P Command Reference

3.4 Line feed amount

The amount of line feed is the amount of vertical movement from the print position of one line to the print position of the next line.

HHHHHHHHHHHHH

The line feed amount is specified with ESC 0, ESC 2, ESC A, and ESC 3.

 Within a single line of text, the tallest character is determined, and the baseline is moved so that the top

edge of that character is at the vertical print position.

 The tallest character within a line becomes the line height.

Line feed amount

 If characters are underlined, 4 dots are added to the line height.

The underline is placed underneath of the characters when horizontal writing and above of the characters when vertical writing. When underline for both horizontal and vertical characters are existing in the same line, 8 dots are added for the heght of the line.

 If the line height is greater than the specified line feed amount, the line height is used as the actual line

feed amount. In this way, even if the specified line feed amount is small, the upper and lower lines will not overlap.

ESC/P Command Reference

Description

 The left margin and the right margin use the left edge of the physically printable area as the reference.  The area between the left edge of the physically printable area and the specified number of columns is

specified as an unprinted area. The left margin position is the right edge of the specified column. (Character width*n)

 The setting is in the range 0≤ (character width*n) ≤x. Settings outside that range are ignored. However, x is

a value dependent on the media.

 The area between the left edge (first column) to the nth column is specified as an unprinted area.  The position of the left margin is the character width (when this command was specified)*n from the left

edge. The character width when the margin specified includes the settings for the space between characters, setting for full size or half size characters. In addition, when a pitch of 10 cpi (=30 dots), 12 cpi (=25 dots) or 15cpi (=20 dots), compressed characters or double-width characters are specified, that character width is considered as the unit. However, character styles that increase the character width are not applied.

 The horizontal print position is moved to the left margin position.  If the left margin setting is not at the beginning of the line, the left margin is specified after a line feed.

The beginning of the line indicates the left margin position for left alignment; for right and center alignment, it means that no image or character is entered on the line.

 Even if the character width is changed after the left margin has bee specified, the left margin position does

not change.

 A left margin setting that puts the left margin position to the right of the right margin position is ignored.  The left margin should be specified at least one column (10 cpi=30 dots) less than the right margin.

(If the character width (when the command was specified)*n is greater than the right margin-30 dots), the setting is ignored.)

 If the difference between the right margin position and the left margin position is less than one character,

that character is ignored.

 When proportional pitch is specified with the ESC p command, a character width of 10 cpi (=30 dot) is

applied.

 If the print media is continuous length tape, the printing orientation is landscape and the page length is not

specified, commands specifying the left margin are ignored.

 If the minimum margin has been set to 3 mm and the printing orientation is landscape, the left margin

Description

 The left margin and the right margin use the left edge of the physically printable area as the reference.  The right margin position is the right edge of the specified column. (Character width*n)  The setting is in the range 1≤(character width*n)≤x. Settings outside that range are ignored. However, x is

a value dependent on the media.

 Left margin≤print area<right margin  The position of the right margin is the character width (when the command was specified)*n from the left

edge. The character width when the margin specified includes the settings for the space between characters, setting for full size or half size characters. In addition, when a pitch of 10 cpi (=30 dots), 12 cpi (=25 dots) or 15 cpi (=20 dots), compressed characters or double-width characters are specified, that character width is considered as the unit. However, character styles that increase the character width are not applied.

 The horizontal print position is moved to the left margin position.  If the right margin setting is not at the beginning of the line, the right margin is specified after a line feed.

The beginning of the line indicates the left margin position for left alignment; for right and center alignment, it means that no image or character is entered on the line.

 Even if the character width is changed after the right margin has been specified, the right margin position

does not change.

 A right margin setting that puts the right margin position to the left of the left margin position is ignored.  The right margin should be specified at least one column (10 cpi=30 dots) greater than the left margin.

(If the character width (when the command was specified)*n is less than the left margin+30 dots, the setting is ignored.)

 If the difference between the right margin position and the left margin position is less than one character,

that character is ignored.

 When proportional pitch is specified with the ESC p command, a character width of 10 cpi (=30 dot) is

applied.

 If the print media is continuous length tape, the printing orientation is landscape and the page length is not

ESC D Specify horizontal tab position

ASCII: ESC D [n]k NUL Decimal: 27 68 [n]k 0 Hexadecimal: 1B 44 [n]k 00h

Parameters

1≤n≤255, 0≤k≤32

ESC/P Command Reference

Description  The horizontal tab position is the character width (when the command was specified)*n from the left

margin.

 Enter n values in ascending order and end the settings with NUL.  If an n value is smaller than a previous one, tab setting is ended.  Even if the character width is changed after the horizontal tab positions have been specified, the horizontal

tab position settings do not change.

 ESC D NUL cancels all horizontal tab positions.  If the left margin is moved, the horizontal tab positions are also moved by the same amount.  Up to 32 horizontal tab positions can be specified. However, horizontal tab positions beyond the right

margin are invalid and only become valid when a change in the right margin setting or left margin setting moves the print area to include those tab positions.

 The character width when the horizontal tabs are specified includes the settings for the space between

characters, setting for full size or half size characters. In addition, when a pitch of 10 cpi, 12 cpi or 15 cpi compressed characters or double-width characters are specified, that character width is considered as the unit.

 When proportional pitch is specified with ESC p, horizontal tab positions are specified at 10 cpi.  When the printer is turned on, a horizontal tab position is specified every 8 columns at 10 cpi.

Even if the character width is changed before the horizontal tab positions has been specified, the horizontal tab positions do not change.

Description

 Specifies a barcode image.  Any data extending beyond the right margin is ignored.  Since the check digit is generated automatically from the barcode data, the check digit is not sent as

 With CODE39, ITF (I-2/5), CODABAR, CODE128, GS1-128 (UCC/EAN-128) or RSS Expanded, the buffer

length for the barcode image is about 22 cm. A barcode longer than 22 cm will not be printed.

 The characters that can be printed with CODE128 and GS1-128 (UCC/EAN-128) are the 128 ASCII

characters and the special codes FNC1, FNC2, FNC3 and FNC4. Codes assigned to the special codes:

FNC1: 86h, FNC2: 81h, FNC3: 80h, FNC4: 84h

 The control codes and special codes appear as spaces when characters are printed below CODE128 and

GS1-128 (UCC/EAN-128) barcodes.

 The control codes appear as spaces when characters are printed below CODE93 barcodes.  Special code FNC1 can also be printed with RSS Expanded.

This special code also appears as a space when characters are printed below the barcode. Code assigned to the special code:

FNC1: 86h

 The width can be set to extra extra small only with CODE128 and EAN128.  Characters are not printed below the barcode when the width is set to extra extra small.

What is the QR Code Structured Append setting?

QR Codes have Structured Append settings. A long character string can be partitioned into 2 to 16 partitions and printed. With ESC/P commands, it is necessary to enter only the number of partitions. For example, if the print data is partitioned into 3 partitions, the barcode data is as follows:

ESC i Q or q [1st parameter] [1st set of barcode data] \\\ ESC i Q or q [2nd parameter] [2nd set of barcode data] \\\ ESC i Q or q [3rd parameter] [3rd set of barcode data] \\\

Refer to the following for specifying settings for 3 through 6 in [Parameters].

ESC/P Command Reference

3. Structured append

setting:

This determines whether or not the barcode data is partitioned. If the data is not partitioned, enter 0. When not partitioning, the values of 4 (code number), 5 (number of partitions), and 6 (parity data) are ignored; therefore, enter 0 as a dummy value for these parameters.

4. Code number: This indicates which number the ESC/P command for that QR Code is.

For example, if it is for the second of four partitions, this is 2; for the fourth this is 4.

5. Number of partitions: This is the number of partitions.

6. Parity data: This is the value (in bytes) of exclusively OR’ing all the print data (print data

before partition). Entering the same value as for the partitioned QR Code ESC/P command indicates that these codes are linked.

What is exclusive OR’ing in bytes?

The data is exclusively OR’ed (XOR’ed) in bytes and in order. For example, putting a character string into hexadecimal gives 31h, 32h, 33h, 34h.

Character OR’ed (XOR’ed) in bytes Results

XOR of 31h and 32h 0011 0001 ^= 0011 0010 0000 0011 (03h)

XOR of 03h and 33h 0000 0011 ^= 0011 0011 0011 0000 (30h)

XOR of 30h and 34h 0011 0000 ^= 0011 0100

Note

If this parity value is incorrect, the correct QR Code is not generated.
