    Label lenght on Zebra ZQ510

    Nicola Lazzara

      Hello to all, i must print in xamarin.forms application (for Ios) a label ZPL with dynamic height. I want to print all is included on my ZPL. My originally problem is similar to this : Re: IMZ320 Printer prints extra blank space after ptint .


      After the above discussion i change my settings, and Now my code for this command is (in bold the new command) :


             private bool SetPrintLanguage(IConnection connection)


                  //string setLanguage = string.Format("! U1 setvar \"device.languages\" \"zpl\"\r\n\r\n! U1 setvar \"formats.cancel_all\" \"\"\r\n\r\n!U1 setvar \"ezpl.media_type\" \"continuous\"\r\n\r\n! U1 setvar \"media.type\" \"journal\"\r\n\r\n! U1 getvar \"device.languages\"\r\n\r\n");




                  byte[] response = connection.SendAndWaitForResponse(Encoding.UTF8.GetBytes(setLanguage), 1000, 1000);

                  string s = Encoding.UTF8.GetString(response, 0, response.Length);

                  if (!s.Contains("zpl"))


                      string error = "Not a ZPL printer.";

                      return false;


                  return true;



      But when i print now, the print always ends at a fixed length of about 22 cm, and if my content in the ZPL goes beyond it's cut. What am I doing wrong? I would like to be able to print exactly the entire contents of the string that contains the ZPL.


      Thanks in advance.
