MP-4000 TH POS Printer Rev.1.4 Programmer’s Manual

1 Commands

The MP-4000 TH printer has a series of programming commands that may be used in the remote mode. Two types of commands can be sent:

1.1 Direct command

In this mode, a simple ASCII code is enough to command the printer. For example:

ASCII CODE : LF DECIMAL : 10 HEXADECIMAL : 0A

This command causes the printer to perform a line feed.

1.2 Control sequence

In this mode, more than one code may be sent to command or program the printer. This “control sequence” always starts with the ASCII code “ESC”, “FS” or “GS”. For example:

ASCII CODE : ESC W 1 DECIMAL : 27 87 01 HEXADECIMAL : 1B 57 01

This command switches the printing mode to “expanded”. Following is a summary of all commands accepted by the MP-4000 TH printer.

22-aug-2007 Firmware Release: 1.5

MP-4000 TH POS Printer Rev.1.4 Programmer’s Manual

2 Using the command summary

The following section lists and describes all resident commands including command parameters. The command syntax is as follows:

•ESC P is a command without parameters;

•ESC Q n is a command with one parameter only;

•ESC K n1 n2 is a command with two parameters;

•ESC D n1...nk is a command with a variable number of parameters.

A character ‘h’ following an alphanumeric string represents an hexadecimal number. A number with no ‘h’ following it is in decimal mode. An italic item is a parameter to the escape function.

Note: MP-4000 TH printer is capable of interpreting ESC/Bema commands and

ESC/POS commands.

3. ESC/Bema Commands

3.1 Operation Commands

The following section details each of the commands presented in the Command Table, ESC/Bema section.

GS F9h 5 00h

[Function] Select ESC/Bema operation mode.

[Format] ASCII GS F9h 5 00h Hexadecimal 1D F9 35 00 Decimal 29 249 53 0

[Description] Tells printer to interpret ESC/Bema commands from now.

[Notes] ● This command saves data on printer flash memory and therefore is

slow, which may affect printer performance and funcionality if mixed with

other faster commands. Please, use with caution.

● When ESC/Bema mode is enabled and a DB25 serial interface is connected, the printer will automatically change its flow control to RTS/CTS.

GS F9h 20h 30h

[Function] Select ESC/Bema temporary operation mode.

[Format] ASCII GS F9h 20h 30h Hexadecimal 1D F9 20 30 Decimal 29 249 32 48

[Description] Tells printer to interpret ESC/Bema commands from now.

[Notes] ● This command doesn’t writes anything on flash memory, so it can be

used anyway.

● When ESC/Bema mode is enabled and a DB25 serial interface is connected, the printer will automatically change its flow control to RTS/CTS.

22-aug-2007 Firmware Release: 1.5

MP-4000 TH POS Printer Rev.1.4 Programmer’s Manual

GS F9h 1Fh 31h

[Function] Return to previous set of commands configured before temporary setting.

[Format] ASCII GS F9h 1Fh 31h Hexadecimal 1D F9 1F 31 Decimal 29 249 31 49

[Description] Tells printer to interpret the command set that was configured before an

temporary set has been done.

ESC @

[Function] Initializes the MP-4000 TH printer.

[Format] ASCII ESC @ Hexadecimal 1B 40 Decimal 27 64

[Description] All settings, including character font, line spacing, left margin, right

margin, intensity and inverted mode are canceled.

ESC b n

[Function] Select sensor to signalize.

[Format] ASCII ESC b n Hexadecimal 1B 62 n Decimal 27 98

[Range] n = 0, 1, 48, 49 [Default] n = 0

[Description] When n = 1 (or n = 49), PE signal reflects drawer sensor. When n = 0 (or

n = 48), PE signal reflects paper sensor.

[Notes] PE is a signal from the parallel interface.

ESC v n

[Function] Activate drawer.

[Format] ASCII ESC v n Hexadecimal 1B 76 n Decimal 27 118 n

[Description] Activate drawer pin for n milliseconds (-50ms < n < 200ms).

22-aug-2007 Firmware Release: 1.5

MP-4000 TH POS Printer Rev.1.4 Programmer’s Manual

ESC w

[Function] Performs a full paper cut.

[Format] ASCII ESC w Hexadecimal 1B 77 Decimal 27 119

[Description] This command operates the auto cutter, performing a full cut in the

paper.

[Notes] When presenter is activated there is a minimum receipt size (roughly 3.3

inches) to avoid paper jam inside the presenter. If the receipt size is less than the minimum, the full cut command will automatically add line feeds to perform the cut.

ESC m

Hexadecimal 1B 2A 21 n1 n2 b1 ... bn Decimal 27 42 33 n1 n2 b1 … bn

[Description] This command programs bit image for 24 bits, in double density where

n1+n2*256 is the number of bit-columns that will be sent (see Bit images and graphics) and b1...bn are the bytes that compose the bit

image. For each column one may need 3 bytes to complete. So, if you

need to send an image with an 8-column width you may send 24 bytes

to fill those columns. A full line has ‘N’ bit columns so a full line will need N*3 bytes. If the image you want to print has less than ‘N’

graphic columns, a LF must be sent to complete line printing. Text and

graphic can be mixed in the same line. If the printer is used with

pograms that convert text to graphics, the printer is slower than if the

printer is sent ASCII text. See N value in the Table 2.

direction for the bit image.

• yL, yH, select the number of data bytes (yL+yH×256) in the vertical

• Data outside the printing area is read in and discarded on a dot-by-dot

basis.

• The position at which subsequent characters are to be printed for raster bit

position), ESC \ ( Set relative print position), and GS L (Set left margin ). If

the position at which subsequent characters are to be printed is not a

multiple of 8, print speed may decline.

• The ESC a (Select justification) setting is also effective on raster bit images.

• d indicates the bit-image data. Set time a bit to 1 prints a dot and setting it

to 0 does not print a dot.

slow, which may affect printer performance and funcionality if mixed

with other faster commands. Please, use with caution.

● When ESC/POS mode is enabled and a DB25 serial interface is

connected, the printer will automatically change its flow control to

DTR/DSR instead of RTS/CTS.

developed. Therefore, there may be a time lag between receiving this command and transmitting the status, depending on the receive buffer status.

• When the printer ID transmission is specified with (1 = n = 3) or (49 = n =

51), one byte code is transmitted.

• When Auto Status Back (ASB) is enabled using GS a, the printer ID transmitted by GS I and the ASB status must be differentiated using the table in Appendix III.

GS a n

[Function] Enable/Disable Automatic Status Back (ASB).

[Format] ASCII GS a n

Off 00 0 Error status disabled. 2 On 04 4 Error status enabled. Off 00 0 Paper roll sensor status disabled. 3 On 08 8 Paper roll sensor status enabled.

4-7 - - - Undefined.

[Details] • If any of the status items in the table above are enabled, the printer

transmits the status when this command is executed. The printer automatically transmits the status whenever the enabled status item changes. The disabled status items may change, in this case, because each status transmission represents the current status.

• If all status items are disabled, the ASB function is also disabled.

• Since this command is executed after the data is processed in the receive buffer, there may be a time lag between data reception and status transmission.

• When the printer is disabled by ESC = (Select peripheral device), the four status bytes are transmitted whenever the status changes.

• When using DLE EOT, GS I, or GS r, the status transmitted by these commands and ASB status must be differentiated, according to the procedure in Appendix III, Transmission Status Identification.

• The status to be transmitted are as follows:

Because the specified status bits transmitted from the ESC/POS commands are fixed, the user can confirm the command to which the status belongs, as shown in the following table.

When using Auto Status Back (ASB), however, process the consecutive three-byte code (except for XOFF) as ASB data after confirming the first byte of the ASB. Otherwise, the status transmitted by using the GS r and the status of the second and following bytes of the ASB cannot be differentiated.
