Printer Out of Paper

The printer (Dell B2375dfw Mono Multifunction Printer) says out of paper. Then I loaded paper but it still won't print. It prints the test pages and if I scan to print also it works. But when I connect my laptop and try to print it keeps saying it is out of paper when it isn't. How do I fix this?

I unplugged everything and kept it for about a minute before I plugged everything back and switched it on. Still didn't work.

I removed the paper tray and cleaned the dust and ensured the paper are not folded and properly aligned the size too. It still didn't work.

I made sure that the actual paper size and type are matching in the printer system as well as in my laptop before I gave the print command. It didn't work either.
