ZPL II Data Matrix Help

I am not 100% clear on where you are encountering your problem.
* At the application not sending the correct data string to the Data Matrix barcode printer?
* At the printer - not supporting what you are sending?
* Or somewhere else?

And I'm not clear on what you mean by: multiple pieces of information
* How are you attempting to separate the multiple pieces?
* How many characters are in each separate piece?
* How are you attempting to 'connect' the multiple pieces of data in the data string?

On: it says:

It is recommended to limit the amount of data encoded in each symbol to 800 characters or less if possible

It sounds as though you are attempting to create your own Data Matrix barcode via your own application.

If so, my first recommendation would be to try downloading a different 2D generating application and see if that meets your needs.
One of many possibilities might be:

If that meets your needs, then you have identified that the code(s) you are sending to the Zebra printer are not correct.
If the codes are not correct, I'd recommend you contact Zebra Support
or the support from one of their distributors.

The issue I am having is that I need the data matrix to read two different variables and 1 constant. '^FN1' is a custom coded variable along with '^FN2'. Along with these 2 variables I need the matrix to hold one constant '^FDxxx'. I had originally typed the code as follows:

^FO20,40 ^BXN,3,200,48,48 ^FN1 ^FN2 ^FDxxx ^FS

The issue that came up was that only the ^FD field printed. I tried to rearrange the order and it seems to print the last data field on the line. I have also tried commas, double commas, and plus symbols to connect them together and none of them made a difference. I'll try to contact Zebra tech support to see if I can get any help.

Contacting Zebra Support is a good idea.

One thing you neglected to mention since the Values themselves MIGHT be influencing the results.
What do the ^FN variables contain?

^FN1 = custom date stamp (mmddyy)
^FN2 = sequence #
