Hi Guanghui,
If I set the print option as Do not print for the sales receipt, in that case custom receipt type 7 is working... as I do not have attached printer, I am saving as PDF.. When I set the sales receipt as Always print, I am getting error while printing the custom type receipts.
Please check my code
