Can't connect #11

Closed tomhannen closed 2 years ago

tomhannen commented 2 years ago

Steps to replicate:

Power up the printer. The printer is flashing a blue LED. When I run the app (from the binary in the zip file), and click on Connect, nothing happens:

ScreenFlow

I am using: Cat thermal printer "MINI Printer", which registers as bluetooth name "MX06" using the official Fun Print iOS app MacBook Pro M1 running MacOS 12.4

Any advice for fault finding appreciated

That printer name is not in the supported list. There are a bunch of cat/rabbit/panda printer variations and they not only have different BLE names, but different protocols (undocumented) too. I'm sorry, but try changing the code to search for that name and see if the protocol matches the other printers.

Thanks - I'll try building in XCode and give it a go. Whereabouts in the files is the variable for changing the code please?

The code failed when I added "MX06" to the *szTypes array. But then I also added "PRINTER_CAT" to the ucTypes array and it worked, kind of!

It prints approximately the top quarter of each image I feed it:

Feeding works correctly.

Hope this helps with any debugging

I can't debug this without having the printer here; sorry, I wish I could help more.
