停止滚动打印机 [英] Stop scrolling printer

问题描述

我正在从我的结算项目（C＃windows应用程序）打印发票，发票大小可能会有所不同。



我设置的页面大小为6英寸宽度和5英寸高度..



即使我的发票只有2行，它也会占据整个5英寸高的纸张并推出..



一旦打印内容完成，我可以将其配置为停止卷纸，这样我可以节省纸张吗？



我正在使用点阵打印机和卷纸..



任何想法？

I'm printing an invoice from my billing project(C# windows application) the invoice size may vary.

I've set a page size of 6 inches width and 5 inches height..

Even if my invoice is just 2 lines it would take up the whole 5 inches height of paper and roll out..

Can i configure it to just stop rolling paper once the print content is finished, so that i can save paper?

I'm using dot matrix printer and rolling paper..

any ideas?

这是代码：

this is the code:

try
            {

                DataTable dtCompany = ObjBL.getCompany();
                decimal Vl;
                Vl = 0;
                Font PrintFont;
                clsCommon.getPrinter("[Rec]");
                Position = 0;
                PrintFont = new Font("Calbri", 10, FontStyle.Bold);
                Position = 75;
                if (dtCompany.Rows.Count > 0)
                {
                    PrintFont = new Font("ARIAL", 10, FontStyle.Bold);
                    e.Graphics.DrawString("" + dtCompany.Rows[0]["Company_name"].ToString() + "", PrintFont, Brushes.Black, 75, Position);


                    Position = Position + 20;
                    PrintFont = new Font("Calbri", 9, FontStyle.Regular);
                    e.Graphics.DrawString("" + dtCompany.Rows[0]["Address"].ToString() + "", PrintFont, Brushes.Black, 60, Position);
