-
-Before start create your Python ESC/POS printer instance, you must
-see at your system for the printer parameters. This is done with
-the 'lsusb' command.
-
-First run the command to look for the "Vendor ID" and "Product ID",
-then write down the values, these values are displayed just before
-the name of the device with the following format:
-
-  xxxx:xxxx
-
-Example:
-  Bus 002 Device 001: ID 1a2b:1a2b Device name
-
-Write down the the values in question, then issue the following
-command so you can get the "Interface" number and "End Point"
-
-  lsusb -vvv -d xxxx:xxxx | grep iInterface
-  lsusb -vvv -d xxxx:xxxx | grep bEndpointAddress | grep OUT
-
-The first command will yields the "Interface" number that must
-be handy to have and the second yields the "Output Endpoint"
-address.
-
-By default the "Interface" number is "0" and the "Output Endpoint"
-address is "0x82",  if you have other values then you can define
-with your instance.

 not all, even used, are cheaper and easy to get.
