zpl what's the difference between 200dpi and 300dpi?

I have a question. I'm new to ZPL language I used zebra designer to create a label in 200dpi. If I want to make the same label but in 300dpi. What does it change in my zpl code exactly? I was thinking of the dimension, like in

^LL799

799 will change to another size, but is there anything else?

EDIT:

My goal is to create a C# application to print label on my zebra printers.

The user will choose if it's a 200dpi or a 300dpi and then the right code is sent to GenericText/Only to print on my printer (print to GenericText/Only is required I can't change that). So if you know a way to do that in C# I take it too.

Thanks in advance

To switch resolution, the ZPL template needs to change in order for the label to be printed correctly. Basically it's just a matter of scaling by 3/2 for most fields. For example:

200dpi          300dpi
--------        --------
^FO40,40    ->  ^FO60,60
^BY4        ->  ^BY6

And so on. I coded a converted that does the opposite, just change the multiplier from 2/3 to 3/2 and you should be good to go:

public static void Main()
{
    var evaluator = new MatchEvaluator(Converter);

    const string pattern = @"(?<=\^[A-Z0-9]{2,3},?)([0-9]+,[0-9]+)";
    const string input = @" ... ZPL CODE HERE";

    Console.WriteLine(Regex.Replace(input, pattern, evaluator));
    Console.WriteLine();
    Console.WriteLine("Press any key to quit...");

    Console.ReadKey();
}

public static string Converter(Match match)
{
    var (w, h) = (double.Parse(match.Value.Split(',')[0]), double.Parse(match.Value.Split(',')[1]));
    var (wNew, hNew) = ((int)Math.Floor(w * 2 / 3), (int)Math.Floor(h * 2 / 3));
    return wNew + "," + hNew;
}

This will not convert some fields, such as barcodes. You need to change those manually. You should use http://labelary.com/viewer.html to check the results and adapt. Open 2 viewers and paste 203 and 300 dpi, then select the resolution and label size and compare.
