上打印卷纸 [英] Printing on roll paper

问题描述

我正在使用C＃与的WinForms。我想打印账单上纸卷。纸张的宽度是3英寸，但纸张的长度是动态的（其辊纸）。长度取决于有多少项目有在列表中。例如。在一个购买，如果有100个项目出售那么这将是相当长的辊子，而对于单个项目购买这将是小的长度。

当我打印报告，结束作业后，打印机弹出最后一页比我更需要。它送出纸张只要A4尺寸。我想打印所需的线路，然后停止打印。 我用了一卷纸，而不是A4或A3和爱普生LQ-300 + II打印机。

要更具体地，印刷进行时，总是以页大小的单元。如果我设置页面为3英寸x 8英寸然后我总是最后一个打印输出是8英寸长的倍数。如果我有一个9英寸账单打印，我结束了一个16英寸的打印输出，浪费了7英寸的纸张。我怎样才能最后一页是唯一的，只要它需要打印？

下面是code：

 私人无效printDoc_PrintPage（对象发件人，PrintPageEventArgs E）
        {
            字体printFont =新的字体（宋体，12）;
            诠释Y = 15;
            e.Graphics.DrawString（线路，printFont，Brushes.Black，0，Y）; Y = Y + 20;
            e.Graphics.DrawString（线，printFont，Brushes.Black，0，Y）; Y = Y + 25;
            e.Graphics.DrawString（线，printFont，Brushes.Black，0，Y）; Y = Y + 35;
            e.Graphics.DrawString（线，printFont，Brushes.Black，0，Y）; Y = Y + 45;
        }
 

解决方案

您是否尝试过使用一个网页，只是一条线长？

省略上下边框，并且可以打印不停。

现在增加一点（这样的页面可以撕下），退出。

试试这个：

  PAPERSIZE pkCustomSize1 =新PAPERSIZE（第一个自定义大小，100，200）;

            printDoc.DefaultPageSettings.PaperSize = pkCustomSize1

I am using C# with Winforms. I am trying to print bills on a paper roll. The width of the paper is 3in but the length of the paper is dynamic (its a roll paper). The length depends on how many items are there in the list. E.g. in a purchase if there are 100 items sold then it will be quite long roll while for a single item purchased it would be of small length.

When I print the report, after the end job, printer eject the last page more than I need. It eject paper as long as A4 size. I want to print the required lines, then stop printing. I use a roll of paper, not A4 or A3 and an Epson LQ-300 + II printer.

To be more specific, printing is always done to page-sized units. If I set the page to be 3in x 8in then I always end up with a printout that is a multiple of 8in long. If I have a 9in bill to print, I end up with a 16in printout, wasting 7in of paper. How can I print with the last page being only as long as it needs to be?

Here is the code:

private void printDoc_PrintPage(Object sender, PrintPageEventArgs e)
        {
            Font printFont = new Font("Courier New", 12);
            int y = 15;
            e.Graphics.DrawString("a Line", printFont, Brushes.Black, 0, y); y = y + 20;
            e.Graphics.DrawString(" Line", printFont, Brushes.Black, 0, y); y = y + 25;
            e.Graphics.DrawString(" Line", printFont, Brushes.Black, 0, y); y = y + 35;
            e.Graphics.DrawString(" Line", printFont, Brushes.Black, 0, y); y = y + 45;
        }

解决方案

Have you tried using a page that is only "one line" long?

Omit the upper and lower border, and you can print non stop.

Now add a bit (So the page can be torn off) and eject that.

Try this:

            PaperSize pkCustomSize1 = new PaperSize("First custom size", 100, 200);

            printDoc.DefaultPageSettings.PaperSize = pkCustomSize1
