How to print a double quote using a Zebra printer with EPL?

Question

In Java, I want to print a label with a String as the input:

 String command
            = "N\n"
            + "A50,5,0,1,2,2,N,\"" + name + "\"\
            + "P1\n";    

But when the input (name) has a double quote character ("), it is blank and prints nothing. I have tried using the replace function:

name.replace('"', '\u0022');          

but it doesn't work. I want that double quote printed in label, how can I do this?

Answer 1

Sending the " character in the text field of the EPL string makes the EPL code think it is the end of the string you are trying to print.

So, if you want to send(and print) "hello" you have to put a backslash before each " character and send \"hello\"

You also have to do that for backslashes.

So, your (EPL)output to the printer would have quotes to begin and end the string, and \" to print the quote characters WITHIN the string :

A30,210,0,4,1,1,N,"\"hello\""\n

Also remember you have to escape to characters to build a c# string so in c# it would look like this: outputEPLStr += "A30,210,0,4,1,1,N,\"\\"hello\\"\"\n";

[which contains 6 escaped characters]
