While there are "parcel points" in Poland, I've never seen them advertising a document printing service, and they're also being rapidly displaced by the spread of Paczkomaty - automated self-service parcel collection and sending booths.
Yes, but you're not addressing the thrust of the argument. Certainly print shops don't exist in Poland, but that doesn't mean that getting prints done is inconvenient in Poland if you don't have your own printer.
In sufficiently-developed countries like Poland, you don't need print shops, but it's not because "nearly everyone has printer accessible at home or at work." (That's not even true; many people don't have color printers either at home or at work!)
Print shops never existed for the sake of making one print or one copy; the way they made their money was commercial, volume printing. Sign printing; poster printing; flyer printing; etc. "Consumer" printing/copying was always a side-business.
No matter how developed your city, commercial print shops still need to exist, because consumer printers just aren't up to the task of producing thousands of pages per hour, reliably, day-in-day-out; and because there's real labor involved in collating and feeding all that paper. Especially for weird paper shapes that need cutting (e.g. business cards.)
No, the reason Poland doesn't have consumer print shops, is because the commercial printers (and package services) who used to offer walk-in consumer printing as a convenience service, have been out-competed in that space by the lower margins offered by online document/photo print-and-deliver services (who can serve Polish customers from anywhere in the EU very cheaply, and so don't need to have a local presence in Poland.)
> that doesn't mean that getting prints done is inconvenient in Poland if you don't have your own printer.
It is inconvenient in Poland as there is no easy to use way to get your stuff printed.
There are some print shops, but focusing on specialist/large prints - and just few of them in a city, definitely not on every corner. Printing a single A4 page would cost me about 5% of printer cost (travel cost, printing itself, time of travel).
That does not mean that they survive.

In Poland such places are mostly gone (some survive near universities) as nearly everyone has printer accessible at home or at work.
Some are at places where people need printing (government offices) but charge massive fees.

No such thing in Poland and closest equivalent does not offer printing as service (exceptions may apply).
