There 3 different type of printers:
USB(idVendor, idProduct, interface, in\_ep, out\_ep)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Based on pyusb and libusb-1.0
* ``idVendor`` is the Vendor ID
* ``idProduct`` is the Product ID
* ``interface`` is the USB device interface (default = 0)
* ``in_ep`` is the input end point (default = 0x82)
* ``out_ep`` is the output end point (default = 0x01)
Serial("devfile", baudrate, bytesize, timeout)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Based on pyserial, default values are based on the defaults set by
DIP\_SWITCH\_1 on the documentation(hardware side).
* ``devfile`` is an alphanumeric device file name under /dev filesystem (default = /ev/ttyS0)
* ``baudrate`` is the Baud rate for serial transmission (default = 9600)
* ``bytesize`` sets the serial buffer size (default = 8)
* ``timeout`` defines Read/Write timeout (default = 1)
Network("host", port)
^^^^^^^^^^^^^^^^^^^^^
Based on socket
* ``host`` is an alphanumeric host name, could be either DNS host name or IP address.
