Thanks for your reply.
Perhaps you remember, perhaps not but 3 month ago you (and community) have help me to start from zero and create an app in two versions for Windows and Android .
It comunicates with Arduino devices, pick up data etc.
Recently I am going to make a raport printout (or pdf) from both versions but I am starting as previously from B4J.
I know that I can use pdf printer in Windows but I don't know if it is possible in Android.
May you advice me the easiest way to do it concidering this 2 versions ?
May I use something (I mean the code) from B4J in B4A ?
