DLE ENQ n
[Name] Real-time request to printer
[Format] ASCII DLE ENQ n
Hex 10 05 n
Decimal 16 5 n
[Range] n = 2
[Description] The printer responds to a request from the host specified by n.
n = 2: Recovers from an error after clearing the receive and print
buffers.
[Notes]
This command should not be used within the data sequence of another command that
consists of two or more bytes. For example,
If you attempt to transmit ESC 3 n to the printer, but DTR (DSR for the host computer)
goes to MARK before n is transmitted, and DLE ENQ 2 interrupts before n is received,
the code <10>H for DLE ENQ 2 is processed as the code for ESC 3 <10>H.
This command n = 2 is valid only when a mechanical error or an auto-cutter error has
occurred.
DLE ENQ 2 enables the printer to recover from an error after clearing the data in the
receive buffer and the print buffer.
The printer retains the settings (by ESC !, ESC 3, etc.) in effect when the error
occurred. The printer can be initialized completely by using this command and ESC @.
This command is enabled only for errors that have the possibility of recovery

32 ≤c1 ≤c2 ≤255
0 ≤x ≤14 (Font A)
0 ≤x ≤12 (Font B)
0 ≤d1 ... d(y x x) ≤255
[Description] Defines user-defined characters.
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. When only one character is desired, use c1 = c2.
x specifies the number of dots in the horizontal direction.
[Notes]
Consecutive character codes for multiple characters can be defined in one definition.
When specifying only one character, specify c1 = c2.
"d" is definition data that indicates the pattern for " x" dots in the horizontal direction
starting from the left edge. If " x" does not satisfy the number of dots in the character
configuration pattern, the remaining dots on the right are spaces.
The number of bytes required to download a character definition for one character is "
y" x " x".
In the definition data, a "1" represents a dot that is to be printed, and a "0" represents a
dot that is not to be printed.
Independent downloaded character definitions are possible for each font.
The font is selected by the "ESC !" command.
The defined downloaded characters are cleared in the following circumstances:
1) When "ESC @" is executed
2) When deleted by "ESC ?"
3) When the printer is reset or turned off
[Default] The internal character set

ESC * m nL nH d1...dk
[Name] Select bit-image mode
[Format] ASCII ESC * m nL nH d1...dk
Hex 1B 2A m nL nH d1...dk
Decimal 27 42 m nL nH d1...dk
[Range] m = 0, 1
0 ≤nL ≤255
0 ≤nH ≤3
0 ≤d ≤255
[Description] Selects a bit-image mode using m for the number of dots specified by
nL and nH

Rev. 1.00 - 11 -
SRP-500
Divide the number of dots to be printed by 256. The interger answer is nH and the
remainder is nL. Therefore, the number of dots in the horizontal direction is calculated
by nL + 256 x nH.
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 0 to not
print a dot.
The bit-image modes selectable by m are as follows.
m No. of Vertical Dots Dot Density Adjacent Dot Maximum number of dots
0 8 Single Density Permitted 252
1 8 Double Density Permitted 504
[Notes]
If the values of m and nH are out of the specified range, the following data is processed
as normal data.
After printing a bit image, the printer returns to normal data processing mode.
The relationship between the image data and the dots to be printed is as follows.
ESC - n
[Name] Turn underline mode on/off
[Format] ASCII ESC – n
Hex 1B 2D n
Decimal 27 45 n
[Range] n = 0, 1, 48, 49
[Description] Turns underline mode on or off,
When n = 0 or 48, underline mode is turned off.
When n = 1 or 49, underline mode is turned on.
[Notes]
Underlines can be printed for all characters, but not for the space set by HT.
This command and ESC ! turn underline mode on or off in the same way.
If n is out of the specified range, this command is ignored.
[Default] n = 0

Decimal 27 63 n
[Range] 32 ≤n ≤255
[Description] Cancels user-defined characters.
[Notes]
This command cancels the pattern defined for the character code specified by n. After
the user-defined characters is cancelled, the corresponding pattern for the internal
character is printed.
This command deletes the defined pattern for the specified code in the character font
selected by the "ESC !" command.
If a user-defined character has not been defined for the specified character code, the
printer ignores this command.

Hex 1B 44 n1...nk 00
Decimal 27 68 n1...nk 0
[Range] 1 ≤d ≤255
0 ≤k ≤32
[Description] Sets horizontal tab positions.
n specifies the column number (counted from the beginning of the line) for setting a
horizontal tab position.
k indicates the total number of horizontal tab positions to be set.
[Notes]
The tab position is set at [character width x n] from the beginning of the line. The
character width includes the right-side space of the character, and is twice the normal
value when double-width is specified.
This command deletes horizontal tab positions that have already been set.
When "n = 8" has been set for the horizontal tab position, the printing position moves to
the ninth digit when HT is executed.
Up to 32 tab positions can be set. Data exceeding 32 tab positions is processed as
normal data. Input <n>k in ascending order and place a NUL code <00>H 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.
The previously specified horizontal tab positions do not change, even if the character
width changes.
[Default] The default tab positions are at intervals of 8 characters (columns 9,
17, 25, ...) for the font B (12 x 14).

[Description] Selects paper detector(s) to output paper end signals, using n as
follows:
Bit Off/On Hex Decimal Function
Off 00 0 Paper roll near end sensor disabled.0
On 01 1 Paper roll near end sensor enabled.
1 Off 00 0 Paper roll near end sensor disabled.
On 02 2 Paper roll near end sensor enabled.
Off 00 0 Paper roll end detector disabled.2
On 04 4 Paper roll end detector enabled.
Off 00 0 Paper roll end detector disabled.3

4 - - - Undefined
5 - - - Undefined
6 - - - Undefined
7 - - - Undefined
[Notes]
It is possible to select multiple detectors to output signals.
Then, if any of the detectors detects a paper end, the paper end signal is output.
Detectors are switched when executing this command.
Because of this, the paper-out signal switching may delay depending on the receive
buffer state.
[Default] n = 15

[Notes]
The printer goes off-line after printing stops.
The paper roll near-end sensor is an option, therefore, if the paper roll near-end sensor
is enabled by this command when the sensor is not equipped, it does not stop printing.
The paper roll near-end sensor is enabled when either bit 0 or 1 is 1.
The paper roll end sensor is a sensor which is always used to make an effective to stop
printing.

ESC v
[Name] Transmit paper sensor status
[Format] ASCII ESC v
Hex 1B 76
Decimal 27 118
[Description] Transmits the status of paper sensor( s) as 1 byte of data
[Notes]
GS r 1 can also be used to check the status. GS r is recommended for transmitting the
paper sensor status. ESC v is not a recommended command.
When DTR/DSR control is selected by DIP switch (Handshaking) with a serial interface,
the printer transmits the status after confirming that the host is ready to receive data. If
the host computer is not ready to receive data, the printer waits until the host becomes
ready.
When XON/XOFF control is selected by DIP switch (Handshaking) with a serial
interface, the printer transmits the status without confirming whether the host computer
can receive data.
The peripheral device status to be transmitted is as follows:
Bit Off/On Hex Decimal Function
Off 00 0 Paper roll near end sensor : paper adequate
0,1 On 03 3 Paper roll near end sensor : paper near end
Off 00 0 Paper roll end sensor : paper present
2,3 On 0C 12 Paper roll end sensor : paper not present
4 Off 00 0 Fixed
5 Off 00 0 Undefined
6 Off 00 0 Undefined
7 Off 00 0 Undefined
