Printing receipts with 80mm thermal printer and Zoho Creator

Printing receipts with 80mm thermal printer and Zoho Creator

I have a sales form in my Zoho Creator app and I would like to print receipts for customers.

Question 1: From what I've read on this forum there's no way to submit and have the receipt print automatically, you'd have to go through the printer dialog, correct?

Question 2: Is it possible to create a record template for printing to a 80mm thermal printer and how?

Question 3: And lastly can this be accomplished with an iOS device and a Bluetooth printer? My ideal setup would be to run my Zoho Creator app in an iPad and printing a 80mm receipt to an iOS-compatible thermal printer. Second option would be a Mac mini and a thermal printer but I'd really prefer the iPad setup.

Any advice and references are greatly appreciated.
