Hello, I have some problem with LINK-OS SDK: I can't print Barcodes!
The others elements (Image, Text, Shape) were printed, but when I try to print a Barcode it print my method parameters (DrawBarcode) on the card!

This is my C# code (taked from GitHub - Zebra/LinkOS-PCCard-Samples at ConnectAndPrint_ZXPSeries1and3_C#  and GitHub - Zebra/LinkOS-PCCard-Samples at CenterBarcode_ZXPSeries3_C# ):

            int errValue;   // value of 0 indicates no errors            msg = string.Empty;            try            {                if (InitGraphics(_asciiEncoder.GetBytes(drvName), out errValue) == 0)                {                    msg = "Printing InitGraphics Error code: " + errValue.ToString();                    return;                }                int rotation = 0; // origin lower left and no rotation                int barcodeType = 0; // Code 39                int barcodeWidthRatio = 2; // narrow bar = 2 dots, wide bar = 5 dots                int barcodeMultiplier = 2; // {2..9}                int barcodeHeight = 75; // 75 dots                int textUnder = 1; // true                string barcodeData = "123456789";                //To calculate the full length of a Code 39 bar code:                //L = [(C+2) (3R + 7) - 1] X Where                 //L = Length of bar code                //C = Number of characters                //R = Ratio of wide-to-narrow bars                //X = Number of dots times 0.0033 inches per dot (0.08847 mm per dot); for the 5:2 ratio, X = Dots times 2                //See ZXP3 SDK Manual for the forumulas used to calcuate the length of other barcode types.                // Calculate the length of the barcode                int C = barcodeData.Length;                double R = 5.0 / 2.0;                int X = 2;                int length = (int)((C + 2) * (3 * R + 7) - 1) * X;                int startX = (int)Math.Floor((CARD_WIDTH - length) / 2.0); //Center barcode horizontally                int startY = (int)Math.Floor(((CARD_HEIGHT - barcodeHeight) / 2.0) + barcodeHeight); //Center barcode vertically                // Sends Barcode data to the Monochrome Buffer                if (DrawBarcode(startX, startY, rotation, barcodeType, barcodeWidthRatio, barcodeMultiplier, barcodeHeight, textUnder, _asciiEncoder.GetBytes(barcodeData), out errValue) == 0)                {                    msg = "Printing DrawBarcode Error: " + errValue.ToString();                    return;                }               // Prints the Graphics Buffer (Front Side)                if (PrintGraphics(out errValue) == 0)                {                    msg = "Printing PrintGraphics Error code: " + errValue.ToString();                    return;                }            }            catch (Exception ex)            {                msg += "PrintJob threw exception " + ex.ToString();            }            finally            {                // Starts the printing process and releases the Graphics Buffer                if (CloseGraphics(out errValue) == 0)                {                    msg = "Printing CloseGraphics Error: " + errValue.ToString();                }            }
Please help!
