Open your PDF in Nitro PDF Pro -> Under Convert tab, select the To Image option.
In the Pop-up window, select Mutiple-page TIFF in the Image format section to export every pages simultaneously, and select the DPI at 300 or higher for best quality.
Click Convert and wait -.- (it can take a while if the file is big *insert skull emoji*)
Find the converted file in your folder, right click on the file and select Convert to PDF with Nitro PDF Pro
(This will probably take a while as well so just be patient) (It might also crash but just keep trying π)
Save your PDF and use that rasterized file to print.
