Print to Zebra TLP2844 using concatenate strings



Is it possible to use a concatenate string to print to the Zebra TLP 2844 label printer? I have set up my templates using ELP in a constant and they print off fine but now I need to be able to allow the user to enter information each time the program is run. I have split the code up into a concatenate strings and added controls but now the label won't print. I have checked the ELP code and it seems fine. Do I need to add a line feed constant after ever line after my control "? Any ideas are much appreciated.

There shouldn't be a problem to do this. Have you looked at the output of the concatentate stirng? Is it similar to the constant you have?

Yes. The outputs are identical apart from the controls which I have added. I do not get an error of any sort, it just dosen't print.

EPL is picky about the end of lines. I would make sure that you are terminating each command line with a line feed. It will ignore the carriage return if it is included. The important part is that each command must be on its own line.
