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.
