将视图转换为字节数组以进行打印

Question

I have a fragment that outputs plain text to the screen for viewing tickets. I am working on implementing a print function to print the content to a receipt printer (Star Micronics SM-T300i). I have the SDK installed and working, but I'm just not connecting the dots on how to do this. All the examples seem to be converting things into bitmaps from byte arrays, etc. This is my first printing app so I'm just not familiar with the process. I want to print the same XML file I use to view on the screen to the printer in text mode so it uses the printers native fonts. Am I on the wrong track? Thank you.

Answer 1

I ended up using an ArrayList for each line item to print. It is a receipt so there's no special formatted. For example:

list.add(("Ticket NO: " + data.get("ticketNo") + "\n").getBytes());

I then sent the entire list to the printer SDK command to print. Trying to print what the user sees on the screen was not necessary and easier to just output the information like this.
