如何使用EPPlus for A4纸张创建Excel文件

Question

My current project use EPPlus to create Excel files. These files are printed by the user and I'm trying to force the Excel file to print in only one A4 page, regardless the width og the content.

Actually, when the file is printed, it takes two pages and the second contains just one column.

My code:

ws.PrinterSettings.Orientation = eOrientation.Landscape;
ws.PrinterSettings.PrintArea = ws.Cells[ws_dimension_adress];
ws.PrinterSettings.TopMargin= 0;
ws.PrinterSettings.RightMargin = 0;
ws.PrinterSettings.BottomMargin = 0;
ws.PrinterSettings.LeftMargin = 0;
ws.Cells[ws_dimension_adress].AutoFitColumns();
ws.Cells[ws_dimension_adress].Style.Font.Size = 9;

The result: The result provided by my code

What I need:

I searched things like "autofit to A4 page", eso but no solution yet.

Remark: all the columns are needed. I can't simply delete one before creating the file.

Thanks for helping!

Answer 1

I found the solution.

EPPlus has a printerSettings for this. The line to use is

ws.PrinterSettings.FitToPage = true;

By using this, the default files properties force Excel to print the data in only one page.

Hope this help some other devs.

You can also use this line of code for a specific paper size:

ws.PrinterSettings.PaperSize = ePaperSize.A4;

Hopte this helps some others people.
