			===Command line===

			Plug the USB into your computer or server first.

			In Linux/Mac, the printer should appear at one of the <code>/dev/</code> sockters, which should be a path similar to:

			/dev/usb/lp0

			Try to send some text to the printer:

			$ echo "hello" > /dev/usb/lp0

			If you get an '''permission denied''' error, you can check the permissions of the socket of the printer:

			$ ls -la /dev/usb/lp0

			Which returns something like the following:

			crw-rw---- 1 root lp 180, 2 Nov 6 12:48 /dev/usb/lp2

			In this case, the printer socket is owned by the user <code>root</code> and by the group <code>lp</code>.

			With the <code>groups</code> command you can check if you are part of the <code>lp</code> group:

			$ groups

			If not, you can add yourself with:

			$ sudo addgroup USERNAME lp
