我是调用API添加了自定义纸张,计算后每页应显示30行,
预览正常,可打印时,后10行却打不出来.请大家帮忙看看!
//DBPaperSize 是调用API添加自定义纸张类
DBPaperSize myDBPaperSize = new DBPaperSize();
//SetPrintForm方法添加自定纸张，参数分别是：打印机名，纸张名，宽，长．
myDBPaperSize.SetPrintForm(printDocument1.PrinterSettings.DefaultPageSettings.PrinterSettings.PrinterName,
"enghui", 240, 140); //遍历以取出自定义纸张
string paperName = "enghui";
foreach (PaperSize paperSize in this.printDocument1.PrinterSettings.PaperSizes)
{
if (paperSize.PaperName == paperName)
{
this.printDocument1.DefaultPageSettings.PaperSize = paperSize;
break;
}
}
//设置页边距
this.printDocument1.DefaultPageSettings.Margins.Top = this.printDocument1.DefaultPageSettings.Margins.Top / 2;
this.printDocument1.DefaultPageSettings.Margins.Bottom = this.printDocument1.DefaultPageSettings.Margins.Bottom / 2; //计算打印行数，kVerticalCellLeeway是行间距，
linesPerpage = (PageHeight - TopMargin - BottomMargin) / (8 + kVerticalCellLeeway);
