We use bluetooth thermal printer for a few of our out of internet travelling salesman. Main problem is almost every other bluetooth printer type/brand need a little print layout adjustment. If internet connection isn't an issue, you can try papercut.com or google cloud print or setup you own IPP and connect to normal printer. There are also savapage.org but papercut already work for us so haven't try that one.
