USB Printers

I'm new to this Raspberry Pi and Linux business. I want to run a USB printer (Standard Epson R200 or similar, nothing too exotic) directly off the board. I am not sure how to go about this and what printers are supported and the procedure to install the drivers. Can someone point me in the right direction please?

When I finally get my head round this system I want to run an Epson/Citizen receipt printer off the GPIO using C++ but I realize that I have to get to grips with Linux first :?

Possible, but:
a) You need a printer supported by linux, with drivers suitably compiled for raspbian (debian running on an ARM6 CPU)
b) Your printer's USB port most probably won't be a "single current unit" device, and will not work directly on the PI's USB ports (which only work with a very select few of normal USB devices, that is, keyboards, mice, and very few other low power devices). Which means you need to add an USB hub with its own 5V power supply, to power your printers USB device.
