• TM220B票据打印[原创]

    主要是通过XML文件做模板来实现打印;
    模板如下：

    317
    318        }
    319    }
    320}
    321

    六、打印调用BOMPrinter.cs
     1using System;
     2using System.Collections.Generic;
     3using System.Text;
     4using System.IO.Ports;
     5using System.IO;
     6
     7namespace BOM.NewUI.PrinterManager
     8{
     9    public class BOMPrinter
    10    {        
    11        /// <summary>
    12        /// 打印
    13        /// </summary>
    14        /// <param name="PrintTypeCode">ACC01 或 OCT01</param>
    15        public static void Printer(string PrintTypeCode)
    16        {
    17            //ACC01  or  OCT01   and so on 
    18            switch (PrintTypeCode.Substring(0, 3).ToLower())
    19            {
    20                case "acc":
    21                    SerialPort sp = BOM.NewUI.PrinterManager.Printer.CreateSerialPort("票据打印机");
    22                    BOM.NewUI.PrinterManager.Printer.Print(sp, PrintTypeCode);
    23                    sp.Close();
    24                    break;
    25                case "oct":
    26                    SerialPort sp1 = BOM.NewUI.PrinterManager.Printer.CreateSerialPort("票据打印机");
    27                    BOM.NewUI.PrinterManager.Printer.Print(sp1, PrintTypeCode);
    28                    sp1.Close();
    29                    break;
    30                default:
    31                    break;
    32            }               
    33        }
    34        /// <summary>
    35        /// 打印DG
    36        /// </summary>
    37        /// <param name="ReportTitle"></param>
    38        /// <param name="ReportContext"></param>
    39        public static void PrintReports(string ReportTitle,string ReportContext)
    40        {
    41            SerialPort sp = BOM.NewUI.PrinterManager.Printer.CreateSerialPort("票据打印机");
    42            Template tt = new Template();
    43            tt.PrintReport(sp, ReportTitle, ReportContext);
    44            sp.Close();            
    45        }
    46    }
    47}
    48

    七、配置文件PrinterConfig.xml
     1<?xml version="1.0" encoding="utf-8" ?>
     2<SerialPortInfo>
     3  <printer name="发票打印机">
     4    <printertype>TM-U220B</printertype>
     5    <porttype>串口</porttype>
     6    <portname>COM5</portname>
     7    <baudrate>9600</baudrate>
     8    <parity>None</parity>
     9    <databits>8</databits>
    10    <stopbits>One</stopbits>
    11  </printer>
    12  <printer name="票据打印机">
    13    <printertype>TM-U220B</printertype>
    14    <porttype>串口</porttype>
    15    <portname>COM2</portname>
    16    <baudrate>9600</baudrate>
    17    <parity>None</parity>
    18    <databits>8</databits>
    19    <stopbits>One</stopbits>
    20  </printer>
    21</SerialPortInfo>

    通过以后的工作后，若以后需要增加一些票据的话，只需在相应在XML文件中添加相应的模板信息再，再在Templete.cs文件中给啬的变量付值 ，就可以实现了。
