|
||||
you have previously installed the following python modules:
|

* pyusb (python-usb)
|

* PIL (Python Image Library)

|
||||
3. Define your printer
|
||||
|
||||
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.
|
||||

||||

||||
4. Define your instance

||||
|
||||
The following example shows how to initialize the Epson TM-TI88IV
|
||||
*** NOTE: Always finish the sequence with Epson.cut() otherwise
|
||||
you will endup with weird chars being printed.
