It is already configured with duplex off in CUPS (Two-sided: None, and Reverse Two-sided: None). Duplex is shown as off both in the print dialog options and in the CUPS configuration. Note that this happens when printing both from a KDE application (Okular) and from LibreOffice, which use different print dialogs. So it doesn't seem to be an application issue, but rather an issue in some print- related package. > > Can someone please tell me which package to enter in the bug report?
