Why are there no note-printing apps?

Question

Android

It has long been possible to buy a bluetooth printer M58 LL or similar,
that is, working on the esc / pos protocol. In play.google I could only find demo programs and
trading ones.
The question arises that no one writes a program because no one needs to print text on a tape in real life,
or people don’t buy small printers, because there are no programs other than cash registers?

Answer 1

IMHO: there are programs for converting text to PDF, for example.
There is Google Cloud Print in the Market.
Well, there are a bunch of programs, such as WPS Office, where you can convert notes, there are Google Docs and Drive - all for mobile.
In my opinion, this is more than enough, if you put your head and hands, and print-not-reprint everything you need.
The main thing is to view the settings properly.
As for the use of these devices, they are highly specialized for their tasks.
