3.1.4 The printer parameter setting
Printer parameter can be set via two ways:
1. Via software to set
You can download the software set tool, instruction refer to setting tool.
2. Via SET (On back side of printer) and LF Combination set
Enter the parameter setting：Press【SET】button and connect the power.
At this time, green indicator will flash once one second. Release 【SET】button
within three flashes. The printer enters into setting status and print related
message. Choose the setting item through 【SET】button. Press 【SET】button
once, the setting item will go to the next and print out the setting value of this
item. Choose the setting value of item through【LF】button. Press 【LF】button
once, the setting item will go to the next.
Exit the parameter Settings：Press【SET】button, after indicator LED
flashed three times, release the button. It will print out “Exit Set Mode” notice
message. Now the set parameters have been saved. Exit the setting mode
and enter into normal working. If you close the power supply of printer directly,
the setting parameter will lose.

returned to normal after the paper
work.
Blink twice, off 1

Printer head is overheat, it will be
back to normal work automatically
after cool down.
Flashing 3 times, off
1 second
The heating plate of printer head is
damaged, irreversible error, need to
repair.
Mark: When the printer is in a state of busy, green light will turn off.
3.3 Self-test and HEX
Self-test can test whether the printer is working properly or not. If the
self-test receipt can be printed correctly, it means the printer is normal except
the interface with the host. Otherwise, the printer will need to be repaired.
Self-test receipt and analysis
In self-test receipt, software version, interface forms, characters and other
configuration information are printed. Self-test receipt shown in the figure
below:

all parameters shown on self-test receipt should be in kind prevail, above
pictures are just for reference.
2. The specific content of each setting item can refers to “3.1.4”section,
you can print a self-test after setting parameters manually to confirm if set up
successfully or not.
Self-test method:
Hold down the "LF" button and turn on the printer, then loosen the button
in 3 seconds, the printer will print out the self-test list.
Hex printing method
Hold the [LF] button and connect the power. At this time, the red indicator
light will flash once one second. After three flashes of indicator, loosen 【LF】
button. The red indicator will continue to flash. After flashing three times again,
the flashing stops. The printer will print out “Hexadecimal Dump”. Now the
printer enters into the hex printing mode.
3.4 Printer initialization
There are two methods for the printer initialization. One is to use the
control code ESC @, by the host sends a command to the printer, through
which using software initialization. The second is to restart the printer.

Chapter 4 Printing commands
4.1 Summary
All the printing commands of SP-RMD12 are fully compatible with traditional ESC printing
commands. The description form of each command is as following,
Command name Function
Format: ASCII: the standard ASCII character sequence
Decimal: the Decimal number sequence
Hexadecimal: the Hexadecimal number sequence
Explanation: the function of command and usage
method
Example: some examples are listed to illustrate the command for better understanding.
The following is the description of each command according to the function of each
command.
4.2 Commands Description
4.2.1 Paper Feeding Commands
LF Feed Line
Format: ASCII:LF
Decimal: 10
Hexadecimal: 0A
Explanation: The printer prints the current line and feeds paper forwards one line.
Remark: One line means the current character line.
ESC J n Dot Line Feed
Format: ASCII: ESC J n
Decimal: 27 74 n
Hexadecimal: 1B 4A n Explanation:

16
The printer feeds paper n dot lines. n=1~255.
This command doesn’t send carriage return and feed line. It won’t influence the later
feed line command.
If you need to feed paper immediately but no carriage return, can use ESC J command.
Line spacing will be enlarged automatically when using commands ESC V, ESC W and
FS W for enlarging characters.
ESC 1 Set n Dot-line Spacing
Format: ASCII：ESC 1 n
Decimal: 27 49 n
Hexadecimal: 1B 31 n Explanation:
The n dot-line spacing is set for future Line Feed command. n=0~255
Default setting n=3 for text printing, n=0 for bitmap printing when using ESC K
command.
The BASIC programs for observing the effect of this command are as
below: FOR I=1 TO 11 STEP 2
LPRINT CHR$(27);CHR$(49);CHR$(I); ’ ESC 1 set line spacing
LPRINT “RMWD TEST” ’ Print character string and feed line
NEXT I
The print result of the above is as following:
4.2.2 Format Setting Commands

17
ESC B Set Vertical Tab Value
Format: ASCII: ESC B n1 n2
n3…NUL Decimal: 27 66 n1 n2
n3…0
Hexadecimal: 1B 42 n1 n2 n3…00
Explanation:
The vertical tab positions are entered as n1, n2 and so on. Character NUL is added at
the end to indicate that the command is over.
VT command is to carry out vertical tab and the paper is fed to the next vertical position. All
input vertical tab positions can be deleted by using this command in ESC B NUL format.
Example: set three vertical tab values at 2nd line, 5th line, 8th line in one page, you
can send the following commands:
ASCII: ESC B STX ENQ BS NUL
Decimal: 27 66 2 5 8 0
Hexadecimal: 1B 42 02 05 08 00
The BASIC programs about the above example are as below:
LPRINT CHR$ (27); “B”; CHR$ (2); CHR$ (5); CHR$(8); CHR$(0); ‘ESC B command
LPRINT CHR$(11); ‘VT command
LPRINT “SPRM1”; ‘print character string
LPRINT CHR$(11); ‘VT command
LPRINT “SPRM2”; ‘print character string
LPRINT CHR$(11); ‘VT command
LPRINT “SPRM3” ‘print character string
The print result of the above program is as following:
VT Carry out Vertical Tab Value
Format: ASCII: VT
Decimal: 11
Hexadecimal: 0B
Explanation: Feed paper to the next vertical tab position which is set by ESC B

18
command.
Notice: if there is no vertical tab value setting, or the current position equals or is
beyond the last vertical tab position, VT command is to feed paper one line only
(same to LF command).
ESC D Set Horizontal Tab Value
Format: ASCII: ESC D n1 n2 n3…NUL
Decimal: 27 68 n1 n2 n3…0
Hexadecimal: 1B 44 n1 n2 n3…00
Explanation:
The horizontal tab positions are entered as n1, n2 and so on, all of which should be
within the line width of this model printer. Character NUL is added at the end to indicate
that the command is over.
All set horizontal tab positions can be deleted by using this command in ESC D NUL
format.
Command HT carry out horizontal tab.
Example: set three horizontal tab values at 2nd, 9th line, 14th character position in one
line,
ASCII: ESC D STX HT SO NUL
Decimal: 27 68 2 9 14 0
Hexadecimal: 1B 44 02 09 0E 00
The BASIC programs for this example are as below:
LPRINT “12345678901234567890123456789012” ’Ruler
LPRINT CHR$(27); CHR$(68);CHR$(2);CHR$(9);CHR$(14); CHR$(0); ’ESC D
command
LPRINT CHR$(9); ‘HT command
LPRIN “HT1”; ‘print character string
LPRINT CHR$(9); ‘HT command
LPRINT “HT2”; ‘print character string
LPRINT CHR$(9); ‘HT command
LPRINT “HT3”; ‘print character string
LPRINT CHR$(13);
The print result of the above program is as following:
