2.3 Paper loading
A. To load a new roll of paper, gently lift the latch on front cover to open the paper cover.
The paper cover does not open all the way, it stops almost perpendicular to the main
body. Please avoid putting any pressure on paper cover while loading paper, to prevent
breakage or causing uneven pressure between Platen, rubber roller, and thermal head,
TPH.
B. Place a new paper roll inside the printer cavity with the leading edge curling downwards.
C. Unroll a small amount of paper and extend it beyond the serrated tear-bar on enclosure,
as shown in Exhibit 2.5 below.
D. Close, by applying even pressure on both sides of paper cover.
E. Use the PF button to feed a small amount of paper and then tear the excess.
Exhibit 2.5
NOTES:
1. Please make sure the paper roll is a heat sensitive paper which meets all specifications.
2. Only use the PF button to feed paper. Never pull the paper out.
3. Do not touch the thermal head, TPH. Transfer of oil or debris on TPH may shorten the life.
4. Do not use a sharp object to open the cover. Only use the latch.
5. Blow away any paper dust inside the printer or on gears.
6. Do not attempt to remove the platen.

8
2.2 Installation
Insert the printer assembly inside the opening on instrument’s front panel.
Open the paper cover, as shown in Exhibit 2.6 and you will notice two screw heads on either
side of the paper cavity. Use a screw driver to turn the screws in clockwise direction. As the
screw turns the clip is raised until the printer is secured by capturing the front panel between
the clip and printer bezel.
Note: The torque used for fastening the screws must not exceed 2kg.cm

3.2 LED Indicator and Paper Feed button
The function of buttons will be different according to the different working mode of printer. In
normal working mode, it is as below:
Paper Peed button (PF): When printer is powered on, the button is in “online” status.
Press【PF】button to feed paper; and release button to stop feeding paper.
The LED indicator for both power and error is the same. (Green)

Damaged printhead. Unrecoverable,
the printer needs to be repaired.

3.3 Self-test and Hex printing
Self-test can test whether the printer is working normally or not. If the self-test receipt can be
printed out correctly, it means the printer is working normally. The self-test does not test the
interface with host. If the self-test does not print the self-test receipt correctly, the printer
needs to be repaired.
The content printed on self-test receipt is: Version No., Interface, Character and other
configuration information.
Self-test is holding down 【PF】 button and turn the printer on. Then within three seconds,
release the button. At this time, the printer will print out self-test receipt.
Hex printing is holding down 【PF】 button and turn on the printer. After the indicator flickers
three times, release the button. The printer will print out “Hexadecimal Dump” and enters into
Hex printing mode.
Cancelling hex printing: Press 【PF】 button constantly three times. Then send 0x00; ②
Restart the printer directly
3.4 Pinter Initialization
There are two methods of printer initialization. One is by using control code ESC @, the host
sends a command to printer to initialize. The other is a hard reset by restarting the printer.

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.

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.

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

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:

LPRINT CHR$(11); ‘VT command
LPRINT “SPRM1”; ‘print character string

16
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 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.
Example: set three horizontal tab values at 2nd, 9th line, 14th character position in one line,

LPRINT CHR$(9); ‘HT command
LPRINT “HT2”; ‘print character string
LPRINT CHR$(9); ‘HT command

17
LPRINT CHR$(13);
The print result of the above program is as following:
HT Carry out Horizontal Tab Value
Format: ASCII: HT
Decimal: 9
Hexadecimal 09
Explanation:
The print position is advanced to the next horizontal tab position which is set by ESC D
command.
Remark: If there is no horizontal tab value setting, or the current position equals or is
beyond the last horizontal tab position, HT command won’t be carried out. If the horizontal
tab position is beyond the current line width, HT command won’t be carried out, either.
ESC f Print Blank Characters or Lines
Format: ASCII: ESC f m n
Decimal: 27 102 m n
Hexadecimal: 1B 66 m n
Explanation:
When m=0, ESC f NUL n will command to print n blank characters
When m=1, ESC f SOH n will command to print n blank lines. n=0~255.
Remark:
When m=0, if the value of n is beyond the current line width, the printer will continue to print
blank in the next line.
When m=1, paper will feed n current line heights.
Example: print 6 blank characters in one line, you can send the following commands: ASCII:

Explanation:
The value of n should be in the range from 0 to the line width of this model printer.
Default n=0, that means no left margin.
This command sets absolute position, and won’t be influenced by character
commands ESC U and ESC W.
Example: set left margin value to 12, you can send the following commands:
commands:
ASCII: ESC 1 ACK Decimal: 27 108 12
Hexadecimal: 1B 6C 0C
The BASIC programs for this example are as below:

This command sets absolute position, and won’t be influenced by character commands
ESC U and ESC W.
After setting this command, the printer will carry out carriage return and feed line as long as
the right margin position is reached.
Example: set right margin value to 12, you can send the following commands:

Explanation:
This command is used to set dot spacing between characters, which is also valid
for Chinese characters.
Default n=0, means no space between characters. (dot is absolute value and won’t be
influenced by enlarging or narrow commands), n=0~255
4.2.3 Character Setting Commands
ESC U Enlarge Width
Format: ASCII: ESC U n
Decimal: 27 85 n
Hexadecimal: 1B 55 n
Explanation:
After inputting this command, the characters, graphics and Chinese characters are printed
at n times of normal width, n=1～8. Default n=1 when the dots are 24, while default n=2
when the dots are 16. These are normal printing width.
Remark: n=1～8, the other value of n will be invalid.
The BASIC programs for observing the enlarging effect of this command are as below:
FOR I=1 TO 3
