C# 양면 인쇄 솔루션(word\excel\그림 인쇄)
1,word의 print와 excel의 printout에 단양면을 설정합니다
2. printdocument의 printsettings의duplex 설정 단양면
시험해 본 후에 효과가 좋지 않았는데, 어제 마침내 MSDN에서 프린터의 단면을 직접 설정하는 코드를 찾았는데, 매우 유용하다.

}사용 방법, word를 예로 들면:

{
//0 check if there are any winword process exist
//if is,kill it
Process[] wordProcess = Process.GetProcessesByName("WINWORD");
for (int i = 0; i < wordProcess.Length; i++)

}사용 방법, excel을 예로 들면, 나는 두 가지 표를 가지고 있는데, 인쇄 페이지 수를 인쇄에 고정시켰다.
public static void PrintExcel(string excelFileName, PrintDocument pd, int iFlag)
{
//0 check if there are any winword process exist
//if is,kill it
Process[] wordProcess = Process.GetProcessesByName("EXCEL");
for (int i = 0; i < wordProcess.Length; i++)
{
wordProcess[i].Kill();
}
object Missing = System.Reflection.Missing.Value;
object objExcel = null;
object objWorkbooks = null;
try
{
objExcel = ExcelTool.OpenExcel(excelFileName);
if (iFlag == 1)
{
objWorkbooks = ExcelTool.GetWorkSheets(objExcel);
object[] parameters = null;
try
{
parameters = new object[8];
parameters[0] = 1;
parameters[1] = 4;
parameters[2] = 1;
parameters[3] = Missing;
parameters[4] = pd.PrinterSettings.PrinterName;
parameters[5] = Missing;
parameters[6] = true;
parameters[7] = Missing;
objWorkbooks.GetType().InvokeMember("PrintOut", System.Reflection.BindingFlags.InvokeMethod, null, objWorkbooks, parameters);
}
catch (Exception ex)
{
throw ex;
}
}
else
{
objWorkbooks = ExcelTool.GetWorkSheets(objExcel);
object[] parameters = null;
try
{
parameters = new object[8];
parameters[0] = 5;
parameters[1] = 5;
parameters[2] = 1;
parameters[3] = Missing;
parameters[4] = pd.PrinterSettings.PrinterName;
parameters[5] = Missing;
parameters[6] = true;
parameters[7] = Missing;
objWorkbooks.GetType().InvokeMember("PrintOut", System.Reflection.BindingFlags.InvokeMethod, null, objWorkbooks, parameters);
}
catch (Exception ex)
{
throw ex;
}
}
}
catch (Exception ex)
{
throw ex;
}
finally
{
if (objWorkbooks != null)
{
ExcelTool.ReleaseComObj(objWorkbooks);
}
if (objExcel != null)
{

}
System.GC.Collect();
}
}마지막으로 A4용지 인쇄 설정을 말하자면 다른 코드는 생략하고 이 문제를 고민하는 사람은 문제가 어디에 있는지 단번에 알아볼 수 있다.
용지 크기에 맞추려면:
pd.PrintPage += (_, e) =>
{
var img = System.Drawing.Image.FromFile(FileName[i]);
e.Graphics.DrawImage(img, 20, 20, e.PageSettings.PrintableArea.Width, e.PageSettings.PrintableArea.Height);
if (i == FileName.Length - 1)
{
e.HasMorePages = false;
}
else
{
e.HasMorePages = true;
}
i++;
};고정 크기라면:
pd.PrintPage += (_, e) =>
{
var img = System.Drawing.Image.FromFile(FileName[i]);
int iWidth = 520;
double hFactor = iWidth / (double)img.Width;
int iHeight = Convert.ToInt32(img.Height * hFactor);
Rectangle Rect = new Rectangle(170, 330, iWidth, iHeight);
e.Graphics.DrawImage(img, Rect);
if (i == FileName.Length - 1)
{
e.HasMorePages = false;
}
else
{
e.HasMorePages = true;
}
i++;
