ImportError: No module named Image about python-escpos HOT 6 CLOSED

I'm sorry about the confusion,
you also need to install python-imaging and pyserial.

I've updated the wiki accordingly.

Thank you.

It still doesn't work properly.  "pyserial" is not in the Pi's repository, so I 
built it from source like the other packages.  It at least prints a hello world 
now, but barcodes only print the text portion.  Images print garbage ASCII, and 
QR codes throw an error.

The line:

Epson.qr("You can read me from your smartphone")

results in the error:

Traceback (most recent call last):
  File "test.py", line 8, in <module>
    Epson.qr("You can read me from your smartphone")
AttributeError: Usb instance has no attribute 'qr'

This is after manually installing the python-qrcode package, and the 
python-imaging package.

Do you mind to tell me which version of python-escpos are you using?

It's version 1.0-1
I also tried version 1.0

Hello,

I've got the same error message AttributeError: Usb instance has no attribute 
'qr'.
I have search and it comes from the version of python-escpos, I've used the 
1.0, so QR code method are available with the package 1.0-1.

I have updated the version of python-escpos and everything is working well as : 

Epson.qr("You can read me from your smartphone")

Hope it will help you

Regards

Ben
