CUPS treats the "landscape" option as a boolean value (IPP_TAG_BOOLEAN). In this case, all values other than "true", "on" and "yes" are considered as false. As a result, using an empty string as the value for the "landscape" option results in the print area still being portrait. Currently, the problem with printing landscape images (png, jpeg, etc.) in Qt programs (e.g. Okular, Gwenview) occurs on Fedora 41 and other distributions using cups-filters v2.0+. The patch adds passing the value "true" instead of an empty string for the "landscape" option, as CUPS expects for changing the orientation.
