It's not just Amazon. I bought a copy of an ARM assembly book from a proper bookseller (Blackwells) which was a proper hardback for a high price--something like £80, and I received a print-on-demand mess with a hardcover. The print was there but barely legible, a dotty mess which gave me a headache. I returned it.

I can see print-on-demand working very well, but not until the quality issues are sorted out. Being charged top dollar for something which is substantially inferior is unacceptable.

Yes, this.

Even hardcover books from "real publishers" have arrived with low print quality. The most common problem book-printing problems I have a real problem with today are

  1. text that is gray (not black) and
  2. text that is dotted (not solid)

I have, 20, 40, and 100+ year old books with phenomenal "solid black text", and they are an absolute pleasure to feast the eyes on. But more importantly, they are not so irritatingly bad while reading them that the bad presentation entirely and unavoidably distracts from the quick and enjoyable consumption of the content itself!

If you ask me, the following checkboxes should be standard ratings on all books sold:

  [ ] "solid, black text"
  [ ] "acid-free paper"
  [ ] <we could add a few here>

Everything else comes after knowing these aspects in my opinion. I guess these would require numeric, measured scores, too, with the binary checkboxes indicating some minimum threshold is surpassed. There are other important factors, too, of course, but getting basic text color and text character solidness is number one, easily.

Related, I used to buy 3rd party black laser printer toner that was guaranteed and warrantied to be made to OEM spec. It never, ever was, no matter how many returns/replacements/retries/print-settings-adjustments/other-part-replacements. Always gray text, always. Buying actual OEM black toner reliably results in (close enough to) jet black text. It costs more, but it's the only way to be sure for self-printed materials AFAIAA.

		Just for a bit of balance, another book I bought was the ZYNQ book and companion materials. It's made by a university in collaboration with Xilinx. They don't hide that because it's niche and low volume, they used a print-on-demand service. I even went and looked them up, and it's a small UK printer with pretty reasonable pricing for self-publishing small runs of books. The quality was great, no problems with it at all. So it /can/ be done.
