You can certainly ZOOM the print on the Fire Tablet, or you can modify the font size before you email it from your computer to the Fire Tablet. I find good recipes on the internet, then cut and paste them into a Word document. I format the recipe, if necessary, to be more easily read. That includes giving it a bigger font. Then I save the Word document with a title, such as Eggplant Parmesan. I then email the document Eggplant Parmesan over to the Fire Tablet, with Eggplant Parmesan in the subject line. Easy peasy.
Well, a little too much fiddling for me. I really like the printed page, big print, in the kitchen.
Here’s a nifty thing to use for that:
With all my recipes in page protectors, if one gets messy I just slip it into a new protector.
I guess I’m just old-school and low-tech.
(I still use my very early version of Kindle - with Calibre to organize everything. That was a pretty neat program, but I can’t seem to get the new versions to work right on the Fire...)
