Depending on how they look internally, it might be worth to check whether these POS system printers can be tapped behind the USB interface - at some point there might be a simple TTL serial data stream. There are also a few older models with serial interface.
While there are some USB host I/F boards available for Arduinos (the Raspberry implements the host I/F), but these are already rather large boxes.

My solution is not an USB-Host - it uses a Serial-USB interface to talk to a host (a PC) though a virtual COM port. Perfect for a PC connection using Christoph Giesselinks printer emulator. If the printer could be tapped, the serial interface stream could be fed easily into it without the need for USB. The ESC/P conversion should be easy, except for special characters and graphics.
