Printer Mechanisms
The printer mechanism comprises a 384-element, thin film head and a stepper motor-drive transport. Head
temperature compensation is utilized to provide constant print quality across a range of operating conditions.
Paper Out: The printer will automatically detect when the paper has run out. The paper signal will blink to
denote that the paper has run out.
Head Thermal Limit: After excessive printing, the paper head temperature may rise to an unusable level. If
this occurs, printing will be suspended until the temperature returns to normal levels.
Preparing the Scale for Use with Printer
1) Fix the weighing platform gently to the body of the scale via the four location points. The slope edge of the platform
should face the front part. (DO NOT press hard on the platform).
2) Plug the mains adapter supplied with the scale into the mains and connect the adapter's output plug to the input
socket at the rear side of the scale.
3) Unpack the printer.Plug the mains adapter supplied with the printer into the mains and connect the adapter’s
output plug to the input socket at the rear side of the scale. Connect the printer with the scale via the RS232 cable
supplied.
4) Connect end B of the supplied USB cable at the back of the scale. Connect end A of the cable to an available USB
port of the computer.
3) Placethescale on a firm and even surface. Press the "ON" key on the keyboard panel on the front side.
4) The display will show “uES2200” and "Scan Zero …"for a while. After this, scale will go to Weighing mode (lb
oz) by default. Now the scale is ready for weighing and counting. This is the normal mode of the scale.
5) Turn the printer ON. The ON/OFF switch of the printer is located at the front left side of the printer.
Operating the Scale
Weighing
Press the LB-OZ key to show the weight on the scale’s LCD. This is the normal weighing mode of the scale.This key
will toggle the weight between lb-oz and gram.
Counting
Press Sample to enter the sampling mode. Press up or down key to increment and decrement the sampling number
respectively by the step of 10. (Pressing the CE key in the sampling mode will exit to the counting mode). Once the
desired sampling number is chosen put the items on the scale and press Sample. The scale will memorize this
sampling number andstart counting the items.
Tare
Press the TARE key to set the weight to zero. This is useful for weighing an item with a container. Put the empty
container and press TARE. The scale weight display becomes zero. The items to weigh or count may now be placed
on the scale. Only the weight of the items (excluding the container) is displayed. “T” appears at the lower left corner of
the LCD when the scale is in Tare mode.
Line Feed
Press Line Feed key tofeed empty lines. This will cause the paper to move forward to the next line.

Printing Mail Labels from the Computer to the Printer via the Scale
Labels can be printed from the computer to the printer using the application program that comes with this
product. To print mailing labels, follow these simple steps:
1. Make sure that the USB scale is connected to your computer and the thermal printer is connected to
the USB scale (see previous instructions for connections).
2. Turn the scale ON.
3. Turn the printer ON.
4. Run the application program.
5. Put the item to be mailed on the scale’s platform to capture the weight from the scale to the application
program (the Weight field will be automatically updated on the program).
6. Supply the other information in the following fields (all are required):
a. Barcode
b. Postal Number
c. Postal Service
d. Zip Code
e. Shipping Address
7. Click Create Label button on the program. A preview of the label can be seen on the lower part of the
application window.
8. Click Print Label button to print this label to the thermal printer.
9. Repeat steps 5 to 8 when printing another label.
Operating Temperature
The scale is designed to operate in a normal room temperature. If subjected to cold or warm temperature, it should be
allowed to reach the room temperature before operating.
Using the Supplied AC Adapter
Connect the AC adapter into the power jack and the output outlet on the rear side of the scale. This adaptor is center
negative 9V.
Operate on a Firm, Flat-Leveled Surface
In order to operate correctly, the scale must be installed on a firm, flat-leveled surface.
Error Displays
Overload Displays when the weight on the platform is more than the scale’s maximum capacity.
PRINTER COMMANDS –Sending Data from PC to Scale for Printing
Name: LINE FEED
Function: Moves the line pointer to the next line
Expression: <0x0A>
Name: DOT FEED
Function: Moves the line pointer horizontally by nnumber of dots
Expression: <0x1B><0x4A><n>
Where n is the number of dots to move from the current horizontal position (n can be 0 to 255)
Name: MULTIPLE LINE FEED
Function: Moves the line pointer by nnumber of lines
Expression: <0x1B><0x64><n>
Where n is the number of lines to move from the current vertical position (n can be 0 to 255)
Name: INTER-CHARACTER SPACE
Function: Sets the inter-character space to 1/6” (fixed)
Expression: <0x1B><0x32>
Name: INTER-LINE SPACE
Function: Sets the inter-line space according to nnumber of dots
Expression: <0x1B><0x33><n>
Where n is the number of dots to set (n can be 0 to 255)
After n is set, the inter-line space is computed as follows (in inches): (n/203)
Example: if n is 30, the inter-line space would be 0.15”
Name: RESET
Function: Restores default settings of the printer and also resets printer buffer
Expression: <0x1B><0x40>
Name: PAPER CHECK
Function: Sets paper checking while printing
Expression: <0x1B><0x63><0x34><n>
If n = 0 no checking if out of paper while printing
n = 2 checks and stops printing if out of paper
Name: CHARACTER SIZE
Function: Sets the width and height of characters to be printed
Expression: <0x1B><0x21><n>
Where n is composed of the following bits:
7 6 5 4 3 2 10 (bit number)
X X D5 D4 X X X X
Xbits can be either 0 or 1 (don’t care bit values)
D5 if 0 sets to normal width of character
if 1 sets to double-sized width of character (double than the normal width)
D4 if 0 sets to normal height of character
if 1 sets to double-sized height of character(double than the normal height)
Examples:
If n is 0 (all bits are 0), then the characters to print will have normal width and height.
If n is 12 (00110000), then the characters to print will have double-sized width and double-sized height.
If n is 8 (00010000), then the characters to print will have normal width but double-sized height
Name: GRAPHICS PRINTING MODE
Function: Sets the options for printing graphics
Expression: <0x1B><0x2A><m><n1><n2><d0d1, d2, d3, …… dk>
Where:
mis the mode –if 0 sets to 8 dots single density
–if 1 sets to 8 dots double density
–if 32 sets to 24 dots single density
–if 33 sets to 24 dots double density
n1, n2 is the size of data in bytes
n1 –lower byte (from 0 to 255)
n2 –higher byte (from 0 to 3)
d–graphics contents
k–if m is 0 or 1, it is equal to (n2 * 256 + n1)
–if m is 32 or 33, it is equal to ((n2 * 256 + n1)*3)
Name: ABSOLUTE POSITION PRINTING
Function: Sets an absolute position for printing in reference to the current position of the pointer (or print head)
Expression: <0x1B><0x24><n1><n2>
Where: n1 is the lower byte of the value to set
n2 is the higher byte of the value to set
The absolute position is computed as follows (in millimeters):
position = (n2 * 256 + n1)*0.125mm
Example: if value is set to 100 (n1 = 100, n2=0), printing position will be set to 12.5mm after pointer
Note: The maximum number of bytes per data transfer from PC to scale is 8 bytes.
[D7 D6 D5 D4 D3 D2 D1 D0]
Where D7 is always the length of the packet including D7
For faster printing, when D7 is 0x08 the scale will stop other functions and just receives the data from PC and
transmit to printer. So, at the end of printing job, PC has to throw byte with D7 other than 0x08.
