As far as I am using the OpenErp Saas environment, I have no way to install this module. I would expect OpenErp to implement this on their commercial server.

Hi Jagdish,

Thx for answering However those instructions cannot be executed on a SAAS environment, making me try to understand why module hw_escpos is made available in SAAS while this dependency to usb.core cannot be met?

Looking forward to your clarification.

Regards,

Denise
