I have been a long time k2pdfopt user via its integration with KindlePDFViewer. Now I have a pdf file with very wide margins which I want to print on a standard letter-size paper (8.5in by 11in) but without the margins and in "2 pages per sheet" mode. I need the reflow feature since the font comes out a little small even after the margins are cropped. Which options should I be using? Since I am printing on paper I need high dpi. I tried to use the dimensions of half of the letter-size page with the highest dpi k2pdfopt allows (-p 10-20 -w 5.5in -h 8.5in -odpi 538) but the output pdf has way too small font size and no reflow.
