I'm currently trying to print a pdf but this pdf has white text and black background, resulting in crazy consumption for the printer. I also need to print it 4 slides per page. I found an app(samsung mobile print) for my note 8 allowing me to do the 4 s p/page. (connecting it with USB port)
But I still didn't find any android app allowing to modify the pdf and change the background color to white. I can do it on my computer with the adobe printing option but not on my phone! And I won't access to desktop always so that's why I need some help here.
list of app tried : xado, ezpdf, adobe, pdf editor, etc...
Thx in advance
