C#2.0中的Crystal Report卷纸打印 [英] Crystal Report roll paper printing in C# 2.0

问题描述

我有一个尺寸为4x2的Crsytal报告，它正在商店中打印账单.
打印机是TVS JuSTBILL打印机[热敏打印机].
它可以正常工作，但是在打印完实际文本后进行打印时，打印机会通过大量纸张从打印机中取出2到3英寸的纸张[卷纸没有任何固定的高度，宽度为4英寸].那张纸浪费了.

是问题.

我们可以在打印完实际打印后停止打印机，以免浪费任何空白页吗?
如何停止打印机以从打印机中弹出多余的纸张.
我正在使用以下代码.

            rptSalesbill abc = new rptSalesbill();
            abc.SetDataSource(ds3.Tables[0]);
            System.Drawing.Printing.PrintDocument printDoc = new System.Drawing.Printing.PrintDocument();
            int i;
            int rawKind = 0;
            for (i = 0; i < printDoc.PrinterSettings.PaperSizes.Count; i++)
            {
                if (printDoc.PrinterSettings.PaperSizes[i].PaperName == "4x2")
                {
                    rawKind = (int)GetField(printDoc.PrinterSettings.PaperSizes[i], "kind");
                }
            }
            abc.PrintOptions.PaperSize = (CrystalDecisions.Shared.PaperSize)rawKind;
            abc.PrintToPrinter(1, true, 0, 0);
            crystalReportViewer1.Refresh();
        }
        private object GetField(Object obj, String fieldName)
        {
            System.Reflection.FieldInfo fi = obj.GetType().GetField(fieldName, BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic);
            return fi.GetValue(obj);
