    Good to know

    Pages are redrawn as images, so text can no longer be selected. 150 dpi suits printing at home; use 300 dpi for small print.

    Questions

    Will it save printer ink?

    Yes. Colour cartridges are not used, and pure black and white also removes grey backgrounds.

    Can I keep the text selectable?

    Not with this tool. Most printers also offer a grayscale option in their print dialog.
