First of all, thank you very much to all involved in the development of ERPNext. I am just a small shop owner but ERPNext has made my work so much easier. I have only touched a little of what this software can offer and I have still a lot to discover.
So far, much of the things that I want to do is simplified by the use of this software but just one thing that is slowing me down, the print button in POS does not do anything. I need to go to sales invoice page and click refresh until the POS invoice shows up to print the invoice. This is time consuming and quite annoying. I was not able to find other posts that mentioned this problem so I hope somebody can help me here. Are there any other configurations that need to be done to be able to print within POS?
As for my setup, I am running ERPNext inside virtualbox running Ubuntu server 16.04 and there is nothing else other than ERPNext installed. I installed ERPNext using the easy install method shown here https://github.com/frappe/bench. I have not done any modifications apart from configuring the software within the web interface. The problem mentioned above occurs in both firefox and chromium.
