When I trying to print a single page on my Dell C2665dnf (printer with full duplex) the print is only on the other side of the page,
the paper is taken by the printer and it looks like it printing an empty page and duplexer taking it immediately back to print the expected page on the other side of the printer.
what I trying to explain is even when I want to print a single side document, the paper going through the printer twice what is really unnecessary. I experiencing it only in Corel, other programs are fine!
