In excel , go to Page lay out - Print titles - Header/Footer - Custom header - Add some text and click on print preview. You can see the left / center and right header getting overlapped. Can you please provide a fix for this.
I have added a sample excel for this.
Thanks for your posting and using Aspose.Cells.
If you check your Excel file in Print Preview, you will see header is crunched. If you save your Excel file into PDF using Save As menu command, you will see header is crunched there too. So it is not a bug and cannot be fixed. Aspose.Cells works same as Microsoft Excel.
I have attached the Excel generated PDF for your reference.
