1. No need to write in bold letter
2. Simple, instead of printing to the printer, just use the PDFjetB4A library to create a PDF
3. No hack needed, you will need an OutputStream to save the PDF
4. You can use FileProvider to share the PDF file, email it etc.

Thank you very much for your comment about bold letters but I want to say that the app is designed to print with a bluetooth printer only so I want to make a virtual one that receives bluetooth output from that app and prints it to pdf file on my phone. Is that possible.
