大家好，我有一个带有DataGridView的WinForm和一些控件。我想从此DataGridView到PrintDocument打印特定的列。我设计了一种带有硬编码标题（如Sr.，Qty，Rate等）的帐单格式。
可能有足够的数据用于多个页面，所以我希望此标题显示在每页顶部，我也想添加页码，在打印完所有行之后，在页面末尾有总计，折扣和应付金额计算我想确保它出现在最后一页的末尾。
编辑：我已成功从选定的列中打印出来，因为我不是学习者，我不知道它是否会在A4以外运行。我想知道Bill Calculation部分如果有很多页面，该部分将在drawDataGridTab2()之后触发吗？
如果您能帮助我了解如何使A4以外的纸张打印而不丢失格式，那该如何做？
贝娄，我正在粘贴新的帐单格式代码。
private void printDocumentTab2_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
//Draw Header
////
Graphics graphic = e.Graphics;
Font font = new Font("Courier New", 12);
float fontHeight = font.GetHeight();
graphic.DrawString(txtSupplierTab2.Text, new Font("Courier New", 20), Brushes.Black, 20, 20);
graphic.DrawString(txtRichAddressTab2.Text, new Font("Courier New", 12), Brushes.Black, 20, 50);
graphic.DrawString(txtCityTab2.Text, new Font("Courier New", 12), Brushes.Black, 20, 105);
graphic.DrawString("Ph: " + txtContactTab2.Text, new Font("Courier New", 12), Brushes.Black, 20, 120);
graphic.DrawLine(new Pen(Color.Blue, 2), 0, 140, this.Width, 140);
//Call method to Draw Headers
drawHeaderTab2(new Font("Courier New", 12, FontStyle.Bold), graphic);
graphic.DrawLine(new Pen(Color.Blue, 2), 0, 165, this.Width, 165);
//Call method to Draw DataGrid
drawDataGridTab2(new Font("Courier New", 10, FontStyle.Bold), graphic);
//Bill Calucation
graphic.DrawLine(new Pen(Color.Blue, 2), 0, 900, this.Width, 900);
//Gross Total at the end of Bill
graphic.DrawString("Total", new Font("Courier New", 12), Brushes.DarkRed, 600, 905);
graphic.DrawString(txtGrossTotal_Tab2.Text, new Font("Courier New", 12), Brushes.DarkRed, 700, 905);
//Discount At the End of Bill
graphic.DrawString("Disc.", new Font("Courier New", 12), Brushes.DarkRed, 600, 925);
graphic.DrawString(txtGrossTotalDisc_Tab2.Text, new Font("Courier New", 12), Brushes.DarkRed, 700, 925);
//Payable at the end of the bill
graphic.DrawLine(new Pen(Color.Black, 1.5f), 600, 945, this.Width, 945);

graphic.DrawString(lblGrandAmmount_Tab2.Text, new Font("Courier New", 12), Brushes.DarkRed, 700, 945);
}
DrawHeader函数
private void drawHeaderTab2(Font font, Graphics g)
{
g.DrawString("Sr#", font, Brushes.Black, 20, 145);
string medicine = dataGridView1.Columns["medName"].HeaderText;
g.DrawString(medicine, font, Brushes.Black, 70, 145);
string qty = dataGridView1.Columns["purchasedQty"].HeaderText;
g.DrawString(qty, font, Brushes.Black, 500, 145);
string rate = dataGridView1.Columns["costPrice"].HeaderText;
g.DrawString(rate, font, Brushes.Black, 600, 145);
string amount = dataGridView1.Columns["grossTotal"].HeaderText;
g.DrawString(amount, font, Brushes.Black, 750, 145);
}
DrawDataGridView功能
private void drawDataGridTab2(Font font, Graphics g)
{
int yCord = 170;
int y1 = 185;
int y2 = 185;
int rows = 1;
foreach (DataGridViewRow dr in dataGridView1.Rows)
{
//g.DrawString(dr.ToString(), new Font("Courier New", 10), Brushes.Black, 10, 150);
g.DrawString(rows.ToString(), font, Brushes.Black, 20, yCord);
string medicine = dataGridView1.Rows[dr.Index].Cells["medName"].FormattedValue.ToString();
g.DrawString(medicine, font, Brushes.Black, 70, yCord);
string qty = dataGridView1.Rows[dr.Index].Cells["purchasedQty"].FormattedValue.ToString();
g.DrawString(qty, font, Brushes.Black, 500, yCord);
string rate = dataGridView1.Rows[dr.Index].Cells["costPrice"].FormattedValue.ToString();
g.DrawString(rate, font, Brushes.Black, 600, yCord);
string amount = dataGridView1.Rows[dr.Index].Cells["grossTotal"].FormattedValue.ToString();
g.DrawString(amount, font, Brushes.Black, 750, yCord);
g.DrawLine(new Pen(Color.Black, 1), 0, y1, this.Width, y2);
yCord += 15;
y1 += 15;
y2 += 15;
rows++;
}

我刚刚创建了一个要打印的模块。它需要更多的微调才能使其完美。
const jwt = require('jsonwebtoken');
const router = express.Router();
const User = require("../models/user");
const Book = require("../models/book");
const router = express.Router();
router.use('/books', passport.authenticate('jwt', { session: false }));
router.param('bookId', (req, res, next, id) => {
Book.findById(id, (e, book) => {
if (e) return next(e);
// Simplified for 'not found', here req.book will just be null. you can make custom error if you want
req.book = book;
return next();
});
});
router.route('/books/:bookId')
.get((req, res) => {
if (req.book) return res.json(book);
return res.status(404).json({ msg: 'Book not found' });
});
// similarly you can add delete and put methods here if you want, and not have to req-query for the book.
router.route('/books')
.post((req, res) => {
const { isbn, title, author, publisher } = req.body
const newBook = new Book({ isbn, title, author, publisher });
newBook.save((err) => {
if (err) return next(err); // note, custom errors can be handy here
// this returns HTTP 201, which is a success, and the newBook which includes its ID
return res.status(201).json(newBook);
});
}).get((req, res) => {
Book.find((err, books) => {
if (err) return next(err);
res.json(books);
});
});
module.exports = router;
