After inline testing for receipt printer modem selected, we recommend Epson TM-m10 bluetooth printer.
If you select other brand's modem, we can't guarantee it can be use, but you still can try to connect it with inline app via below steps :
Turn on both iPad and printer's bluetooth and try to connect each other
Inline app : Click Settings > Food Order Printer > enable Order ticket printing (specific printers only)
Turn off and reopen inline app
There will be a printer icon shows on the top of the right of the order details page
*If the printer icon shows successfully means that the printer can print out the receipt, then it will automatically print out the receipt after pressing Accept during new order came in
