You need to edit in a regular text editor. We have some replacement fields that the standard plist editors don’t like.

I’m pretty sure the example code will be printing to a portable bluetooth receipt printer because that’s the use case that mergAccessory was implemented for even though it can work with any made for iphone accessory as long as you have the protocol docs.
