3.1.3 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 SEL and LF Combination set
Enter the parameter setting: press on 【LF】button and connect the power. At this

11
time, red indicator will flash once one second. Release 【LF】button within three flashes.
The printer enters into setting status and print related message. Choose the setting item
through 【SEL】button. Press 【SEL】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 the 【LF】button, then press【SEL】button, release
【LF】button and 【SEL】button, 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.

3.2 Light and button operation
The function of each button is different according to the different working
mode. Refer the detailed to 3.1.3. The normal working mode is as below,
SEL
Online status switching button. Under online status, the interface printing
is valid. Under offline status, 【LF】button is valid. The default is online status
when printer is power on.
LF
When printer is power on, this button is online status. At this time, pressing
【SEL】button to be offline status and press LF button to feed paper. Press
again to stop paper feeding. During online status, this button is valid.

irreversible, need to repair
Mark: When the printer is in a state of busy, red light will light up.
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:

15
3－4self-test receipt
In the figure, the left one is self-test receipt for serial interface model and
the right one is for parallel interface model. The printing sequence is from the
below to above.
Mark:
1, Due to that the default configuration item may be different when the
printer is out of factory, the font size of self-test receipt and the content of each
configuration is according to the actual content of printed receipt. The above
picture is just for reference.
2, The specific content of each item set can reference "3.1.3 printer
parameters setting" section. After setting manually each time, it can be test
whether the setting is successfully through printing self-test receipt.
Self-test method:
1, Hold down the "SEL" button and turn on the printer, then loosen the
button, the printer will print out the self-test list.
2, Under normal working mode, click SEL button once, then hold down the

16
LF button, at the same time, click the SEL button, the printer will print 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-RMDIIID, SP-RMDIVD 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

18
Explanation:
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
ESC B Set Vertical Tab Value
