As I understand it, the copying of books was the work of slaves. In the Roman Empire slaves did most of the second tier bureaucratic work, ie they were scribes, teachers, recordkeepers, copyists etc. They wouldn't usually originate work, but they kept it and passed it on.
Would scroll merchants and publishers be anxious to help promote an invention that would undermine they value of their inventory and manufacturing process?
OTOH the PP is arguably the most powerful agent of change ever invented. Less than fifty years after its inception in OTL almost 10 million (I think, it could be one million but I think its more, but 10 mill seems incredible, but its the number I remember) books existed in Europe and printing was an established profession. Also, Rome is not the only center of learning in the Roman world, other great cities, less slave dependent, might have use for the PP if Rome doesn't.
Like maybe, Jerusalem. A Jewish based explosion of knowledge and maybe even Industrial Revolution?
The old 'slavery as an enemy to progress' idea is really not all that convincing when you look at historical fact. Now, I'm sure there would be great opposition from copyists and booksellers initially, but I'm sure there was also opposition by waterbearers and sellers to aqueducts, and that didn't stop anyone. Anyd anyway, there is no real risk of saturating the market (books were invariably rare commodities in Rome) and skilled scribes and copyists could always become typesetters and letterwriters. One tends to forget that the printing revolution did not destroy many jobs - there was still demand for written text, and printshops employed plenty of people. It was the output that increased.
As to 'other citioes' - definitely. I don't think Rome - under close supervision by imperial troops (some scholars estimate as many as one in three adult men in the city of Rome were soldiers, though one in ten is more realistic), full of agents, and beset by the intrigue of the senatorial class - is the safest place for printing anyway (though there'd of course be a market - not for handbills, I guess, but for books, sure). The Jews would surely love it (as would the Samarians - which could start interesting little disputes about who gets to sell books where, and who gets to burn whose printing presses). If the Christians are already around as a distinct group, so would they (though if the Jews get the press, I doubt the Christians have a chance). Alexandria, Pergamon, Athens and Antioch are all good candidates for printing centers, too. I'm guessing someone will sooner or later print the 'Secrets of the Pythagoreans' (there goes the mystique), and a number of other sacred texts (frex, Mithraism, the cult of Isis, Iuppiter Dolichenus, and other popular groups could develop a scriptural tradition - probably not like that of Christianity or Judaism, but quite possibly something akin to Buddhist scriptures or the Vedas). Generally, magic will briefly become a lot more popular (because now more peopkle can do it), then less popular (because now more people can find out it doesn't work very well).
Some other ideas:
- it would drive an earlier systematisation of roman law. The whole affair was horribly confused because it was intended as precedent-based case law, but most precedents were recorded only locally. If, say, all provincial courts reported their precedent decisions to Rome annually and they get winnowed by the great jurists and printed with the years Imperial Rescripts and changes to the Praetorian Edict, the price of a slim volume (or a narrow scroll) keeps the provinces in the loop. We may never see the development of what modern legal theory knows as 'Roman Law', ie the Digests of Justinian.
- Government would be run more smoothly because information could be concisely packaged, though updating would be a problem. It might also lead to greater efficiency as the idea of 'proper channels' takes hold.
- It might require greater systemsatisation in all manner of areas, and thereby drive a more investigative and scientific mindset. The Empiricists, for example, would have been very much at home with this. THey might even come out on top if they had the huge collations of fact their approach required, rather than being displaced by concise, but ultimately wrong, theoretical frameworls.
