Raspberry Pi
|
|
************
|
|
|
|
This instructions were tested on Raspbian.
|
|
|
|
Unless you have done any distro with libusb-1.0 on the Raspberry Pi, the
|
|
following instructions should works fine on your raspberry distro.
|
|
|
|
.. warning:: You should **never** directly connect an printer with RS232-interface (serial port) directly to
|
|
a Raspberry PI or similar interface (e.g. those simple USB-sticks without encasing). Those interfaces are
|
|
based on 5V- or 3,3V-logic (the latter in the case of Raspberry PI). Classical RS232 uses 12V-logic and would
|
|
**thus destroy your interface**. Connect both systems with an appropriate *level shifter*.
|
|
|
|
Dependencies
|
|
------------
|
|
|
|
First, install the packages available on Raspbian.
|
|
|
|
::
|
|
|
|
# apt-get install python-imaging python-serial python-setuptools
|
|

# cd pyusb*
|
|
# python setup.py build
|
|
# sudo python setup.py install

|
|
