Alternatively, on the CLI you could use imagemagick to convert your png, tiff, jpg, etc., to pdf: convert scan1.png scan1.pdf convert scan2.png scan2.pdf Then join the two pdf documents into one with two pages, using poppler's pdfunite: pdfunite scan1.pdf scan2.pdf scanned.pdf Then print them. A simple script could batch up the conversion for you, e.g.: for file in $(ls -t *.png | head -8); do convert $file $file.pdf done The above will convert 8 png files to pdf, which you can then pdfunite into a single multipage pdf document before you print it.
