Printing excel chart in high quality

Thanks. This was helpful. I am using A4 size paper 150GSM silk coated. I got paper size in inch from internet as you said, which is 8.27 diagonally x 11.69 vertically so I put that in converter and got 2481 x 3507 resolution.

I tried a lot but couldn't get that resolution image from excel so at last I uploaded my sheet to canva and created the graph there of the required size.

Tomorrow at the office I will print the reports.
