c#打印小票

[test310520]

请问如何用C#打印小票 主要是没做过打印的给列子学学

这个打印方法对你有用。直接传数据和座标值进去就可以了,主要应用是定点打印功能.坐标值以CM为单位(本来是以像数为单位的,转了)

直接打字符串，要对纸张的，调整很费时间

用ReportViewer控件也可以打，不过要打印机驱动支持

[liujiayu10]

什么打印控件不重要，关键是要不断的调整位置，设置好进纸高度

帮我看看这段代码怎么打不出来
void doc_PrintPage(object sender, PrintPageEventArgs e)
{
Graphics g = e.Graphics;
float linesPerPage = 0;
float yPosition = 0;
int count = 0;
float leftMargin = e.MarginBounds.Left;
float topMargin = e.MarginBounds.Top;
string line = null;
Font contentFont = new Font("宋体", 9);
SolidBrush myBrush = new SolidBrush(Color.Black);
linesPerPage = e.MarginBounds.Height / contentFont.GetHeight(e.Graphics);
while (count<linesPerPage&&icount<iDataCount)
{
line =lmenuview.Items[icount].SubItems[1].ToString()+" "+lmenuview.Items[icount].SubItems[4].ToString()+" "+lmenuview.Items[icount].SubItems[5].ToString();
yPosition = topMargin+(count*contentFont.GetHeight(e.Graphics));
e.Graphics.DrawString(line, contentFont, Brushes.Black,
leftMargin, yPosition, new StringFormat());
count++;
}
if(line != null)
e.HasMorePages = true;
else
e.HasMorePages = false;

刚写了一篇关于打印小票的问题，可以去看看du.lovekq.com

打印小票?
你先要搞清楚你用什么打印机？
如果是通过串口或者并口的
就不需要报表控件 直接给串口发打印协议 就打印了
