About Telepen Barcode Font
Telpen is a type of linear barcode font symbology that is used to encode the entire set of 128 ASCII characters without the requirement of shift characters. It is a continuous and varying-length barcode that is created by George Sims of SB Electronic Systems Ltd. in the United Kingdom. It has two modes numeric-only and alphanumeric mode to create barcode images. Telepen barcode also has the capability to represent numerical data in a double-density format, in which an ASCII character is translated into two numeric characters.
As compared to code 128, where a total of four width variants were needed to encode the whole ASCII character set, the Telepen barcode now only requires two variants of barcode width to encode the entire ASCII characters. It works on the sequence of bits rather than individual character encodings, in contrast to the majority of linear barcodes.
Sample of Telepen Barcode Font
Structure
In Telepen barcodes, each 16 module-wide character is created by four to eight bars and spaces, each one to three modules long. The full structure is described below-
- Leading Quiet Region
- Start Symbol (underscore (_))
- Encoded Data Characters
- A Modulo-127 Check Digit
- Stop Symbol (lowercase z)
- Trailing Quiet Region
Telepen barcodes usually begin with ASCII Underscore (_). The bit sequence is 11111010 since it has the code 0x5F. It is shown as 5 pairs of narrow bar/narrow space followed by a wide bar/wide space.
Telepen barcodes usually end with ASCII Character (z). The bit sequence is 01011111 since it has (including parity) code 0xFA. It is shown as a wide bar/wide space followed by 5 pairs of narrow bar/narrow space.
Two additional starts and stop character sets alert the reader that the symbol includes compressed numeric data.
A quiet region must be at least 10X wide or 2.54 mm thick for the Telepen barcodes.
Character Set
The character set of Telepen barcode includes:
- Numerical Digits (0-9)
- Upper Case Alphabetical Letters (A-Z)
- Lower Case Alphabetical Letters (a-z)
- Punctuation Marks (%, +, -, /, $, .)
- Non-printable control characters, including horizontal tab, line feed, and carriage return.
Telepen Barcode Features
Some of the major features of the Telepen barcode are mentioned below-
- Entire ASCII character set representation
- Possible to print using standard printers
- High level of security
- There should be an equal amount of space for each character
Advantages of Telepen Barcode
There are some following advantages that are offered by Telepen barcodes-
- The Telepen barcode is incredibly small in size since it can encode 16 digits or 8 ASCII characters per inch.
- The majority of the top barcode manufacturers together with barcode encoding and decoding equipment support the Telepen barcode.
- It is exceptionally secure and reduces the chance that the data would be incorrectly decoded.
- The maximum fault tolerance limit is 0.4x.
- With a constant ratio of 3:1, the Telepen barcode is very simple to print.
Applications Areas of Telepen Barcode
- Used in the education sector in several nations, especially the UK.
- Used to record information regarding library books and other related items in both public and private libraries.
- Used by the British Automobile Sector and Ministry of Defense.
Create Telepen Barcode Labels
Generate and print Telepen barcode label using DRPU software with either Barcode Designing View method or Barcode Settings method. Use Batch Processing Feature of the software to create multiple Telepen labels with different barcode and text values. Scan the generated barcode labels with any barcode scanner of your choice.
