Much like Arabic, Persian script (الفبای فارسی) is difficult to write, with characters 'changing' depending on context. Think of a text consisting of many, many ligatures. And like in China and Japan the most beautiful calligraphy was held in high esteem.
Reproducing this in print is an enormous challenge, today. For much of the early history of print, Persian printing would produce vastly inferior results in terms of legibility and aesthetics.
The Persian script has presented some difficulties, ever since printing presses were introduced in Iran in the 1600s. The appearance of typewriters created additional problems and the introduction of digital computers added to the design challenges. These difficulties persisted, until high-resolution dot-matrix printers and display devices offered greater flexibility to font designers and the expansion of the computer market in the Middle East attracted investments on improving the Persian script for computers. Nevertheless, certain peculiarities of the Persian script have led to legibility and aesthetic quality issues to persist in many cases. In this paper, I enumerate some of the features of the modern Persian script that made it a poor match to implementation on modern technologies and review the challenges presented by, and some of the solutions proposed for, each new generation of computer printers and display devices. Interestingly, the same features that make legible and pleasant printing/displaying difficult also lead to challenges in automatic text recognition. I conclude with an overview of current state of the art and areas that still need further work.
Fig 3: Persian script: Rules for beautiful writing of letters and letter combinations.
The first challenge in Persian printing was to make the needed metal blocks holding the letters and other symbols (Fig. 6 [not shown here]). This wasn’t a straightforward process. Whereas the Latin alphabet consists of individual letters that are set next to each other, with a small gap between them, Persian letters needed to be connected to each other. Furthermore, the handwritten script was not readily decomposable into separate, non-overlapping symbols. Some examples are provided in the left panel of Fig. 7. The word “mojtame’e,” in which the first two letters “meem” and “jeh” are almost completely overlapped horizontally, as are the next two letters “teh” and “meem,” must be stretched out, so that letters appear side by side, rather than on top of one another.
Besides connectivity of letters and horizontal overlap, certain other difficulties are inherent in the Persian script. Unlike the Latin script, in which letters have regular geometric shapes of comparable sizes (top half of Fig. 8), Persian letters are more curved and exhibit wider variations in width and height. Generally speaking, the Persian script is more compact horizontally, in the sense that the Persian translation of an English sentence tends to take up less space horizontally. This horizontal compactness is mainly due to short vowels not being written out in Persian. However, the Persian script takes up more space vertically, in part due to the need for more line spacing to keep the letters with tall lower parts on one line separated from letters on the following line that have tall upper parts. As a result, the metal type blocks for Persian have greater variations in size, making their manual handling by the typesetter somewhat more difficult.
This wider variation in letter sizes has the side effect of making fixed-width type much less legible than its Latin-script counterpart (more on this, when we introduce typewriter fonts). The bottom half of Fig. 8 contains a few verses of a poem, set with fixed-width and variable-width Persian fonts. The difference in legibility, aesthetic quality, and compactness are quite evident.

But while these inherent technical difficulties were eventually overcome to a certain degree, the aesthetic part, and thus cultural preference were much harder to overcome. Modern Tora rolls are still written by meticulous hands, calligraphy still a valued practice in for printing technology much easier Asian scripts.
Further we tend to emphasise the 'Gutenberg' revolution. And rightly so. But over that we neglect the Stanhope-revolution, taking place much later:

[…] that the diffusion of printing through Islamic Asia in the early 1820s took place as part of a printing global revolution initiated by the mass production of iron handpresses of the kind invented by Charles, Earl Stanhope in 1800. Unlike the cumbrous wooden presses of early modern Europe and its settler populations overseas, the durable, mass-produced, transportable, and easy-to-operate presses of the early 1800s were able to reach regions where printing was unknown and penetrate deeper into reading markets only scratched by the limited print runs of the older wooden presses. Whereas the Gutenberg revolution was effectively confined to Europe and its settler communities in the Americas and Asia, this "Stanhope revolution" was truly global in scale, enabling printing to develop in Iran no less than in Australia, India, Malaya, and large parts of the Americas at the same time. By documenting the contemporaneous appearance in Iran and a series of other regions of iron handpresses and the products on which they depended, the essay argues for the repositioning of Iranian printing as part of a larger global process. Rather than view Iran and other Middle Eastern nations as problematically "late developers" of printing, the essay argues for a reframing of the process in terms of two distinct printing revolutions: Gutenberg's and Stanhope's.

Which makes it necessary to re-frame the question, lifting it from its limits on Persia. While Arabic printing was equally difficult— brilliantly summarized as "Neither Good, Fast, Nor Cheap: Challenges of Early Arabic Letterpress Printing" — the Ottoman Empire did adopt it eventually, albeit equally slowly. With the directly connected economic aspects of market, demand, supply and price.
The Persian scholar Rashid-al-din already accurately described (in both Arabic and Persian language) Chinese block printing ca. 1303.
Note that the question itself already makes the crucial observation:
"the first books in Persian characters were published in Leiden in 1639,":
— Libraire - Expert - Antiquaar ( (Édition en persan) - Jeronimo Xavier & Lodewijck de Dieu: - [Titre en persan] Historia Christi Persice conscripta, simulque multis modis contaminata […]. Latine reddita & animadversionibus notata a Ludovico de Dieu [- S. Petri,- Rudimenta linguae Persicae […]]. Lugduni Batavorum [Leiden], ex officina Elseviriana, 1639.)
The above shows a page from this book, printed with minimalist Farsi-characters — the difference to the much fancier calligraphy is evident), a quite elaborate Latin antiqua, produced in The Netherlands, and showing a very Christian theme. From there, it took a few years to 1817.
Within a few years of 1820, Muslim-owned printing presses were established under state sponsorship in Iran, Egypt, and India, marking the true beginning of printing in the Islamic world. Printing projects had been initiated before this period—most famously by Ibrahim Müteferrika (1674–1745) in Istanbul—but these were isolated and unsustained ventures. None gathered the joint momentum of state support and technological transfer to compare with what emerged simultaneously in Tabriz, Cairo, and Lucknow.

That this all is a bit judging from a eurocentric point of view is also emphasised in Shelton A Gunaratne: "Paper, Printing and the Printing Press",

In which we see that for example Chinese scholars take the view that Chinese society "always produced the optimal number of books", as needed.
So, while in the European one early bestseller was the easily typeset bible, the koran, was and is almost anathema to using printed Arabic for it. Looking at the demand-side in Persia we see a late need emerging for mass dissemination of texts. One example:
The printing of mathematics textbooks in Persian did not begin until the second half of the nineteenth century. The initial stimulus to employ print technology appears to be the founding of Dār al-Funūn, an institution intended to provide instruction in the “new” scientific learning of Europe. Most of the earliest examples of vernacular printed textbooks were either translations of imported European textbooks or adaptations based on the model of these European textbooks.

As such, we might assume that Persian book production was limited by not using the modern printing press earlier. That might not be entirely the case.
Still, in the face of the pretended belief in the superiority of oral transmission, it was generally recognized that all knowledge was important and would disappear without books. This recognition often extended to the realization that all written materials were valuable and required preservation.
The only practical attempts, however, to regulate, if modestly, the flood of books consisted of the production of works that were supposed to take the place of all the previous publications in a given field, and of the composition of handbooks and compendia, but the value and efficacy of these procedures did not remain unquestioned. Before the age of printing and modern technology, this was probably the most that could be done. The Muslim scholars cited here deserve credit for having been aware, if ever so dimly, of the problems resulting from the overproduction of books as an unintended by-product of the intellectual flourishing of their civilization. As it turned out, of making many books there was no end in medieval Islam, and we have every reason to be glad that this was so.

Before 1800, the argument that the spread of printing was delayed by the hold of bazaar copyists over the book market, and the relative cheapness of their product compared with the initial capital required to set up a printing press and sell a large enough number of copies to turn the enterprise to profit, holds some merit.[…]
