#1332 Not able to select duplex scanning

[Clare G Pennell]

I've just downloaded NAPS2 8.2.1 ARM64 so that I can scan from my canon TR4700 printer as Canon drivers are not compatible with my new ARM laptop. I have my printer set up as a and can scan from the glass or feeder. However, the option of duplex under paper source doesn't seem to be available and I want to be able to do duplex scanning. I've tried selecting the TWAIN driver but it says no devices are found and I don't seem to have any different options when I select ESCL driver. Please could you help so that I can do duplex scanning. Thank you.
