    RW 420 Printing Images Upside Down on some printers

    Ronan Egan

      Hi there,

      I have two Zebra RW 420 printers

      One prints receipts perfectly

      Firmware version: S39028

      Software version : SHSCG11x20

       

       

      The other printer prints upside down

      Firmware version: S39029

      Software version : SHCRW11z52

       

      I upgraded the software on the printer with errors to

      Software version : SHCRW11Z62

       

      My questions are?

      Are we using the wrong software version in the first printer?

      Is there a command we can use to send to ZPL so the print image works the same for both?

       

      This is our code used for printing

       

                string setLanguage = "\r\n! U1 setvar \"device.languages\" \"zpl\"\r\n";

       

       

                printer.Connection.Write(Encoding.ASCII.GetBytes(setLanguage));

       

       

                String signatureFooter = "^XA^PON^PW500^MNN^LL500^LH15,0^CFD,9,5";

       

       

                printer.Connection.Write(Encoding.ASCII.GetBytes(signatureFooter));

       

       

                printer.PrintImage(Zebra.Sdk.Graphics.ZebraImageFactory.GetImage(resizedCustomerImage), 0, 0, resizedCustomerImage.Width, resizedCustomerImage.Height, true);

       

       

                printer.Connection.Write(Encoding.ASCII.GetBytes("^XZ"));

       

       

                printer.Connection.Write(Encoding.ASCII.GetBytes("\r\n! U1 setvar \"device.languages\" \"line_print\"\r\n"));

       

       

      Thanks for your help

          Hi Ronan,

          I would recommend updating the firmware on both printers

          The ^PON should make everything print the same direction.  The question is what do you consider right side up?  In ZPL, right side up (Normal rotation) is with the top of the label coming out of the printer last.  This is opposite direction from many printers.  It makes it so that if the printer is hanging from a belt or strap, a second person looking at the printer will see the printout hanging right side up.
