Does that work for msx?
I don't know about various printer formats/protocols but apparently msx supports nec pc-pr201 printer format.

I've newer heard of such format, but indeed MSX had some own "MSX-printer"-format and you can tell if you have such printer by using SCREEN-command. I think it very much depends of the use case... If you are planning to use those Japanese text editors then you really need a printer that has KANJI-font ROM embedded to the printer and I bet finding a modern solution might be hard. How ever if you are more in to European software and want to ie. make your next paper magazine with Dynamic Publisher, then I think you are fine with ESC/P support.

So, it appears the exact nec printer model the Japanese msx standard is supporting is pc 8023.
I haven't come across detailed spec for that but it isn't too much for someone to reverse engineer the printer from the commands sent by msx basic/bios. Probably more info in the pc-8001 computer documents. Also the pr201 is some or what compatible, and found a really good data sheet explaining the driver.

MSX BASIC or BIOS it self does not support any kind of printed graphics, so there is nothing really to reverse engineer. IIRC this "MSX-printter"-setting affects if TABs are converted to spaces or not. You need to find a software that uses the printer you want to figure out in order to reverse the functionality. Back in 80's it was not rare that the functionality was also explained on original printer manual. Practically I have no idea what printer model was most commonly supported by different MSX applications, but indeed it would be nice to find some statistics. I know that out of color printers (rare back then) FS-PC1 was probably most supported.
