Printing Enhancement

Regular Updates I have been using the latest stable version of SumatraPDF for many years, and I am very grateful for this project! Recently, I found a problem when printing files. When printing PDF files, on some printers that cannot automatically print on both sides, it takes a lot of time to sort the paper in order to achieve double-sided printing. The function required is to first select only even pages to print and automatically reverse the page order, then put the printed paper into the printer, and then select only odd pages to print again, so that manual double-sided printing can be achieved. Now, the software needs to add the function of automatically reversing the page order when printing.

The "software" is primarily for viewing on Windows and Windows native printing is thus manual settings (PortPrompt) which if the DRIVER has the ability SumatraPDF printing can control the hardware. Thus the print driver needs to offer a "Duplex" setting, and many do. Check in the older Windows 10 Print Dialog but I believe the Win 11 one can be lacking such controls for some printers ?? Generally such functionality is outside of SumatraPDF control other than if offered by Windows !

Currently none of my printers have a Duplex device (they all use manual flipping) so cant show where one would be available! I would need a driver designed and installed for a duplex printer.

What you are requesting in effect is print pages 1 3 5 7 9 2 4 6 8 10 but that is what the driver does for manual printers.

Hence the 4 options are available and dont see what "enhancing" is needed other than use a suitable manufacturers driver.

I have used printers of different models from different manufacturers. If you need to print a PDF file on the front and back of a paper in order, the more user-friendly (easy to operate) steps are usually: a) Print all the even pages first and in reverse order. After printing, put the paper back into the printer and print all the odd pages again (not in reverse order!). In this way, the order on the paper will be arranged in front and back 1, 2, 3, 4, 5... b) On some models of printers, first select all the odd pages and in reverse order. After printing, put the paper printed on one side in order again, and select to print all the even pages again (not in reverse order!). In this way, the order on the paper is also arranged in front and back 1, 2, 3, 4, 5... Now, I use sumatrapdf to read PDFs, and LibreOffice to print PDF files. The user interface of LibreOffice's print function is as follows, and there is a reverse order option.
