E4 Example: Replace zeros with CRs in bar code data
If the bar code has characters that the host application does not want included,
you can use the E4 command to replace those characters with something else. In
this example, you will replace the zeros in the bar code above with carriage returns.
Command string: E402300DF10D
E4 is the “Replace characters” command
02 is the total count of characters to be replaced, plus the replacement characters
(0 is replaced by CR, so total characters = 2)
30 is the hex value for 0
0D is the hex value for a CR (the character that will replace the 0)
F1 is the “Send all characters” command
0D is the hex value for a CR
The data is output as: 1234
5678
ABC
<CR>
Stop replacing characters
E5 Terminates character replacement. Syntax = E5.
Compare characters
FE Compare the character in the current cursor position to the character “xx.” If
characters are equal, move the cursor forward one position. Syntax = FExx where xx
stands for the comparison character’s hex value for its ASCII code. Refer to the ASCII
Conversion Chart (Code Page 1252), beginning on page 224 for decimal, hex and
character codes.
