Barcodes with Xerox

This Xerox Barcode scalable font with the following type face number

is supported using the intelligent way, meaning the escape sequences and user data are converted to the Barcodes with ELP intelligent format.

ESC-Sequence: <27>(0Y<27>(s1p###v0s0b200T
### Font size in point

Valid characters: Numeric numbers 0-9

Using the interleaving method for printing digits, the code is very compact. Therefor always two digits are coded at a time. The first digit is represented by the bar lines, the second by the spaces.
Start sign (ASCII 167): §
Stop sign (ASCII 168): ¨

The number of message characters is always even. In order to print the code 2of5 interleaved you have to add a small calculation
routine to your application. Each pair of numbers is printed directly as one character using this algorithm:
Value first digit * 10 + Value second digit + 33.

The characters above 126 are implemented at position 161 and above. That means if the result of the calculation is greater than 126 then you have to add 34 to the result.

Examples:
      Number 19 results in 1*10+9+33 = 52 = number ‘4’
      Number 64 results in 6*10+7+33 = 97 = character ‘a’
      Number 93 results in 9*10+3+33 = 126 = character ‘~’
      Number 96 results in 9*10+6+33 = 129. As it's > 126 calculate 129+34 = 163 = character ‘£’
