Sending raw data via usb to linux

Question

I print some shortcuts on a Zebra TLP-2844 printer and do my job fine on windows, sending EPL instructions to a shared USB printer as follows:

type Label.prn> \ my-pc \ zebra

and it seems to work with serial ports with

type Label.prn> COM1

Now I'm trying to do the same on linux, but it gets really hard! My first guess:

cat Label.prn | / dev / bus / USB / 005/002

since my printer is on bus 005, device 002 (checked with lsusb command), but it doesn’t work at all, as I get bad

bash: / dev / bus / usb / 005/002: Permission denied

Any guesses?
