Actually, technically speaking none of the current printers (nothing
since the *very* early inkjets, like the Epson Stylus Color) are
ESC/P2. ESC/P2 is a well-defined printer language with a lot of fonts
and so forth. No Epson inkjets from this century support that. Epson
calls it "ESC/P2 Raster". It's an extension of the positioning
commands from ESC/P2, with commands for actually printing the raster.
What's more, there have been at least a couple of different versions
of those extensions, one that was used until about 1999 and a
different one after that point. So by now, it really shares nothing
but grammar with ESC/P2. And at that, even the extensions have a
different form, and the parameters for a lot of the commands are
printer-specific (you have to know the head configuration and a bit
more to get those right).
So ESC/P2 isn't really correct, but it's a convenient name.
