Designing Labels Using LDS
enter "^D3" <CR> (carriage return) and save it as "D3.txt". Send the file to the printer by
either using the DOS COPY (C:\>copy d3.txt com1) command or by using a terminal
program.
4.2.2 Format Creation
Special Control code functions (see Chapter 5, Special Control Codes) and/or label formats
may be entered directly through the keyboard but this is not the most efficient method if
entering a large amount of data or numerous commands. Large formats and/or numerous
commands should be entered in an ASCII text editor and then uploaded to the printer.
Microsoft® Notepad has been used for the creation of label designs in this manual because
it is simple to use and does not add formatting characters.
The LDS programming language uses thermal dots as the unit of measure. All commands
and parameters, unless noted otherwise, should be entered using dots. The printer is
capable of being fitted with a 203 dpi or a 300 dpi head. The examples contained in this
document discuss a 300 dpi printer.
The conversion values for the 300dpi print head:
Dots/mm
EXAMPLE: A label that is 2" in length would be (2 x 300) = 600 dots.
