Epson SX445W prints small page on A4 paper

[ark91]

I am getting a problem with Epson sx445w. It does not print the proper size. I select the a4 size while printing the document, But the printer prints the document on a small size version on a4. I have tried to print the document through my phone as well but the problem doesn't solve. I also check the copy functionality of the printer and it works fine and the printer copy the full size. Anyone has got the same problem with Epson.
