Hi Felipe, I would be helpful if you added your code to print. The error message isn't enough to help figure out why or how to update your app to fix this. It's not an error I've seen before.
Hi Robin, thanks for answer..
I asked it for my developer and got code right now.. See code bellow:
Impressora conectada = printer connected
Não foi possível conectar com à impressora = was not able to connect printer
Não foi possível realizar a impressão pois houve um problema de conexão = Was not possible print document because had connection problem
Falha na conexão com impressora. Tente novamente = Printer connection failed, try again
Ps: This code is located on printing activity
Here is video showing printing, then i get error (lose connection) on third attempt, then i have to click again to gain connection and print again..
I got error: Falha na conexão com impressora. Tente novamente = Printer connection failed, try again
