excel保存为图片文件，参考

Dim App As New MSExcel.Application
Dim Wb As MSExcel.WorkBook = App.WorkBooks.Open("D:\\test.xls")
Dim Ws As MSExcel.WorkSheet = Wb.WorkSheets(1)
Dim Rg As MSExcel.Range = Ws.UsedRange
rg.copy
ClipBoard.GetImage.save("d:\\abc.jpg")
app.quit

打印，看这个帖子 http://www.foxtable.com/bbs/dispbbs.asp?boardid=2&id=108860&authorid=0&page=0&star=1

Dim Wb As MSExcel.WorkBook = App.WorkBooks.Open("D:\\test.xls")
Dim Ws As MSExcel.WorkSheet = Wb.WorkSheets(1)
Dim Rg As MSExcel.Range = Ws.UsedRange
rg.copy
app.DisplayAlerts=False

Dim doc As New PrintDoc() \'定义一个报表
doc.PageSetting.Width = 215 \'纸张宽度为215毫米
doc.PageSetting.Height = 280 \'纸张高度为280毫米

Dim g= rg1.Graphics
Dim image = ClipBoard.GetImage
\'g.InterpolationMode = InterpolationMode.HighQualityBicubic
\'g.SmoothingMode = SmoothingMode.HighQuality
\'g.CompositingQuality = CompositingQuality.HighQuality
