As an amateur calligrapher and medieval book binding enthusiast:
The thing that makes historically made manuscripts expensive as fuck isn't that they're handwritten. Hell, you don't have to pay a monk, or, assuming a secular book, they were often copied a quire at a time by the university student who wants their own copy from an exemplar (think early torrenting – you rent a quire of the exemplar, and then go home and copy it. eventually, you'd rent out the whole book, section by section, and have your own copy, that you could rent out to your own friends, and so on).
So scribal labor isn't your problem. It's materials cost.
Expensive books are written on vellum, and illuminated with gold leaf. Even cutting out the gold, vellum, being basically leather, costs a shit ton (today, vellum goes for ~$20 for a single 8.5x11 sheet, so imagine the back-then cost, with less efficient cattle farming, etc).
A single book of the bible can end up costing a couple thousand dollars in material costs for the pages alone (i.e. I'm not factoring how much cord, thread, wood, leather, and glue are costing for the binding, which is trivial compared to several thousand dollars in vellum, nor factoring scribal labor, which works out to a good 1 second per character + about an hour per quire for drawing ruling).
What really made books get cheap was automated paper making. Paper can be made from basically garbage (often rags, historically), and with milling, can be turned out quickly and cheaply relative to vellum, cutting your materials costs for book making by a degree of magnitude.
I've never seen a paper mill in TES, but there's paper all over morrowind, so it's obvious that the technology exists, and is cheap enough for paper to be relatively cheap per sheet.
So, we've got paper, and printing is implied to exist, so it's no wonder books are so cheap in TES.
