Using my iMac (OS High Sierra), I have been scanning in hard copy documents using an Epson printer/scanner and saving them as PDF files. Unfortunately, I have been unable to read said files using voiceover on my iPhone 7-plus. Should I get a more robust PDF creator that is compatible with my Epson scanner that allows me to make editable PDF files? I've heard good things about the VoiceDream Reader app; should I just get that? Or should I get an OCR reader? Thank you!
