2-Sided Printing via C#

Question

Hi,
I am currently having an alignment issue - the first page is correctly aligned and then every page after the first is cut off on the left side. I am trying to print double-sided (giving the user the option of long edge or short edge) onto 11x17 inch paper. NOTE: When I manually print a PDF this way it comes out 100% correct. The following code is my print method:
private void invokeJSObjectPrint(object jsObj)
            object printParamsObj = null;
            object[] printerParam = new object[1];
            Type T = jsObj.GetType();
            printParamsObj = T.InvokeMember("getPrintParams", System.Reflection.BindingFlags.InvokeMethod | System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Instance, null, jsObj, null);
            Type printParamType = printParamsObj.GetType();
            // get property values
            object constantsProp = printParamType.InvokeMember("constants", System.Reflection.BindingFlags.GetProperty | System.Reflection.BindingFlags.Public |
                System.Reflection.BindingFlags.Instance, null, printParamsObj, null);
            object interactionLevelProp = constantsProp.GetType().InvokeMember("interactionLevel", System.Reflection.BindingFlags.GetProperty | System.Reflection.BindingFlags.Public |
                System.Reflection.BindingFlags.Instance, null, constantsProp, null);
            object duplexProp = constantsProp.GetType().InvokeMember("duplexTypes", System.Reflection.BindingFlags.GetProperty | System.Reflection.BindingFlags.Public |
                System.Reflection.BindingFlags.Instance, null, constantsProp, null);
            object silentProp = interactionLevelProp.GetType().InvokeMember("silent", System.Reflection.BindingFlags.GetProperty | System.Reflection.BindingFlags.Public |
                System.Reflection.BindingFlags.Instance, null, interactionLevelProp, null);
            object flagVals = constantsProp.GetType().InvokeMember("flagValues", System.Reflection.BindingFlags.GetProperty | System.Reflection.BindingFlags.Public |
                System.Reflection.BindingFlags.Instance, null, constantsProp, null);
            object pSize = flagVals.GetType().InvokeMember("setPageSize", System.Reflection.BindingFlags.GetProperty | System.Reflection.BindingFlags.Public |
                System.Reflection.BindingFlags.Instance, null, flagVals, null);
            object longEdge = duplexProp.GetType().InvokeMember("DuplexFlipLongEdge", System.Reflection.BindingFlags.GetProperty | System.Reflection.BindingFlags.Public |
                System.Reflection.BindingFlags.Instance, null, duplexProp, null);
            object centerProp = flagVals.GetType().InvokeMember("suppressCenter", System.Reflection.BindingFlags.GetProperty | System.Reflection.BindingFlags.Public |
                System.Reflection.BindingFlags.Instance, null, flagVals, null);
            object rotProp = flagVals.GetType().InvokeMember("suppressRotate", System.Reflection.BindingFlags.GetProperty | System.Reflection.BindingFlags.Public |
                System.Reflection.BindingFlags.Instance, null, flagVals, null);
            // set property values
            printerParam[0] = silentProp;
            printParamType.InvokeMember("interactive", BindingFlags.SetProperty |
                BindingFlags.Public | BindingFlags.Instance, null, printParamsObj, printerParam);
            printerParam[0] = this.ocePrint.PrinterSettings.PrinterName;
            printParamType.InvokeMember("printerName", BindingFlags.SetProperty |
                BindingFlags.Public | BindingFlags.Instance, null, printParamsObj, printerParam);
            printerParam[0] = centerProp;
            printParamType.InvokeMember("flags", BindingFlags.SetProperty |
                BindingFlags.Public | BindingFlags.Instance, null, printParamsObj, printerParam);
            printerParam[0] = rotProp;
            printParamType.InvokeMember("flags", BindingFlags.SetProperty |
                BindingFlags.Public | BindingFlags.Instance, null, printParamsObj, printerParam);
            printerParam[0] = pSize;
            printParamType.InvokeMember("flags", BindingFlags.SetProperty |
                BindingFlags.Public | BindingFlags.Instance, null, printParamsObj, printerParam);
            printerParam[0] = longEdge;
            printParamType.InvokeMember("duplexType", BindingFlags.SetProperty |
                BindingFlags.Public | BindingFlags.Instance, null, printParamsObj, printerParam);
            object[] printParamsObjArray = { printParamsObj };
            // invoke print with the updated printer settings
            if (printParamsObj != null)
                T.InvokeMember("print", System.Reflection.BindingFlags.InvokeMethod | System.Reflection.BindingFlags.Public |
                    System.Reflection.BindingFlags.Instance, null, jsObj, printParamsObjArray);
The program opens a PDF document, and then calls this method. The key properties are the duplex mode and the setPageSize flag value; the suppressCenter/suppressRotate seemingly have no effect. Everything works as desired except for this alignment issue. Any help/suggestions would be greatly appreciated. Thank you.

Answer 1

The solution to my problem lied in my default printer settings - all of the margins needed to be set to 0. Came out perfect after doing this.
