Thankfully even USB-connected printers emulate an LPT (see the other comment I left in this tree) and are very likely to accept one of the standard command sets as well as just plain ASCII.
It's similar to the terminal emulation situation: despite being decades old, the VT100 has become a de-facto terminal command set due to its popularity.
