Telepen can be used to represent the full range of ASCII characters. This
covers the standard set of printable characters including numbers, capital and
lower-case letters and punctuation marks as well as the complete set of
non-printable control characters such as carriage-return, line-feed, horizontal
tab, etc.
Telepen can also be used to represent numeric data in double-density mode,
where an ASCII character is re-interpreted as a pair of numeric characters.
There is nothing in the barcode to distinguish between the 2 modes, and the
interpretation of the data as ASCII or numeric is set only by the configuration
of the reading device.
Telepen systems have been implemented in many countries and very widely in the
UK. Most Universities and other academic libraries use Telepen, as do many
public libraries. Other users include the motor industry, Ministry of Defense
and innumerable well-known organizations for many different applications.
Sample of a Telepen Barcode
Note: Please refer to the Class
Reference documentation for more information about the properties and methods
stated in this document.
In order to get a Telepen barcode image, please follow these
steps:
-
Set the Symbology property to Telepen
-
Set the TelepenEncoding property to:
-
Ascii: Allows to encode the full range of ASCII characters
-
Numeric: Allows to encode numeric data in double-density mode
-
Setting up dimensions and quiet zones:
-
Set the BarWidth property (Value is expressed in Inches)
-
Set the BarHeight property (Value is expressed in Inches)
-
Set the QuietZoneWidth property (Value is expressed in Inches)
-
Set the TopMargin and BottomMargin properties (Values are
expressed in Inches)
-
Set the Code property with the value to encode.

Setting up dimensions and quiet zones:
All values for barcode dimensions are expressed
in INCHES by default. However, Barcode Professional supports other unit
of measurement such as Millimeter, Centimeter, and Mils.
For modifying the unit of measurement for barcoding, please set up the BarcodeUnit
property as needed.
