本篇內容介紹了“C#怎么利用PrintDocument定制打印單據”的有關知識,在實際案例的操作過程中,不少人都會遇到這樣的困境,接下來就讓小編帶領大家學習一下如何處理這些情況吧!希望大家仔細閱讀,能夠學有所成!
前言
本文是利用PrintDocument定制打印單據的小例子,僅供學習分享使用,如果不足之處,還請指正。
涉及知識點:
PrintDocument :從 Windows 窗體應用程序打印時,定義一種可重用的可發送到打印機上的對象。 PrintPreviewControl :表示 Windows 窗體應用程序打印預覽的原始預覽部分,沒有任何對話框或按鈕。 Graphics :GDI+繪圖對象 PrinterSettings:設置打印機屬性,如:設置屬性Copies,可以設置打印份數,默認為1, PageSettings:指定應用于單頁打印的設置 DefaultPageSettings:PrintDocument的屬性 PrintPage事件:PrintDocument的事件,通過此事件來繪制需要打印的內容 PaperSize:指定紙張大小 毫米和英寸的換算:打印機是以英寸為單位的,單據設置是以毫米為單位的,所以需要轉換
效果圖如下:
核心代碼
關鍵代碼如下:
using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Drawing.Printing;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Windows.Forms;namespace DemoPrint{ public partial class MainForm : Form { private int width_p = 200;//單位是mm private int height_p = 70;//單位是mm private int margin_lr = 2;//左右邊距 private int margin_tb = 2;//上下邊距 /// <summary> /// 需要打印的內容 /// </summary> public List<PrintInfo> PrintInfos { get; set; } private PrintHelper printHelper = new PrintHelper(); public MainForm() { InitializeComponent(); } private void MainForm_Load(object sender, EventArgs e) { InitInfo(); InitDocument(); } private void InitInfo() { PrinterSettings printSetting = new PrinterSettings(); printSetting.PrintRange = PrintRange.AllPages; int width_in = MM2Inch(width_p); int height_in = MM2Inch(height_p); PageSettings pageSetting = new PageSettings(printSetting); pageSetting.PaperSize = new PaperSize("customer",width_in, height_in); int margin_lr_in = MM2Inch(margin_lr); int margin_tb_in = MM2Inch(margin_tb); pageSetting.Margins = new Margins(margin_lr_in, margin_lr_in, margin_tb_in, margin_tb_in); this.pdControl.DefaultPageSettings = pageSetting; } private void InitDocument() { List<PrintInfo> lstPrintInfos = new List<PrintInfo>(); PrintInfo p0 = new PrintInfo() { PrtType = PrintType.Table, PrtColor = Color.Brown, Row = int.Parse(this.txtRow.Text.Trim()), Column = int.Parse(this.txtColumn.Text.Trim()), Start = new Point(int.Parse(this.txtStart.Text.Trim(new char[] { '(', ')' }).Split(',')[0]), int.Parse(this.txtStart.Text.Trim(new char[] { '(', ')' }).Split(',')[1])), End = new Point(int.Parse(this.txtEnd.Text.Trim(new char[] { '(', ')' }).Split(',')[0]), int.Parse(this.txtEnd.Text.Trim(new char[] { '(', ')' }).Split(',')[1])) }; lstPrintInfos.Add(p0); printHelper.PrintInfos = lstPrintInfos; } /// <summary> /// 轉換毫米到百分之一英寸 /// </summary> /// <param name="mm"></param> /// <returns></returns> private int MM2Inch(int mm) { return (int)(mm * 100.0f / 25.4f); } /// <summary> /// 打印開始事件 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void pdControl_BeginPrint(object sender, PrintEventArgs e) { } /// <summary> /// 打印事件 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void pdControl_PrintPage(object sender, PrintPageEventArgs e) { Font font = new Font("Arial", 14f, FontStyle.Regular); Graphics g = e.Graphics; g.PageScale = 1; g.PageUnit = GraphicsUnit.Millimeter; //先畫一個矩形 Pen lineColor = new Pen(Color.Black, 0.2f); g.FillRectangle(Brushes.Linen,0,0,width_p,height_p); printHelper.Print(g); } /// <summary> /// 打印結束事件 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void pdControl_EndPrint(object sender, PrintEventArgs e) { } /// <summary> /// 打印 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void btnPrint_Click(object sender, EventArgs e) { //打印對話框 if (this.ptDControl.ShowDialog() == DialogResult.OK) { this.pdControl.Print(); } } private void lblColor_Click(object sender, EventArgs e) { ColorDialog f = new ColorDialog(); if (f.ShowDialog() == DialogResult.OK) { this.lblColor.BackColor = f.Color; } } /// <summary> /// 刷新 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void btnRefresh_Click(object sender, EventArgs e) { List<PrintInfo> lstPrintInfos = new List<PrintInfo>(); //表格配置 PrintInfo p0 = new PrintInfo() { PrtType = PrintType.Table, PrtColor = Color.Brown, Row = int.Parse(this.txtRow.Text.Trim()), Column = int.Parse(this.txtColumn.Text.Trim()), Start = new Point(int.Parse(this.txtStart.Text.Trim(new char[] { '(', ')' }).Split(',')[0]), int.Parse(this.txtStart.Text.Trim(new char[] { '(', ')' }).Split(',')[1])), End = new Point(int.Parse(this.txtEnd.Text.Trim(new char[] { '(', ')' }).Split(',')[0]), int.Parse(this.txtEnd.Text.Trim(new char[] { '(', ')' }).Split(',')[1])) }; lstPrintInfos.Add(p0); //標題配置 PrintInfo p1 = new PrintInfo() { PrtType = PrintType.Text, PrtColor = this.lblColor.BackColor, Content = this.txtTitle.Text.Trim(), Size = int.Parse(this.txtSize.Text.Trim()), FontStyle = chkBold.Checked ?
