I have a web app where users can create invoices. I would like users to able to print tags/labels that the web app generates directly from their phones.
I will only be supporting the latest phones. A Chrome Mobile & Android only solution is perfectly acceptable.
I've looked into Google Cloud Printing but, and please correct me if I'm wrong, the gmail account must be the same for the user and the printer in order to print. I would need ~5 users to be able to print from the same printer.
What are the best practicing regarding mobile printing from web apps?
