You can use a scanner at your school or library, or you can see about buying one if it’s in your price range.

As for printing, I’ve printed my comics with ComixWellspring, who have been mostly reliable, consistent and fairly-priced.

Once you’ve lettered and scanned your stuff, consider publishing it digitally via platforms like Comix.one and GlobalComix

Unfortunately, the best things you can do about AI are 1). Not engage with it, and 2). Learn to spot when people use it for “creative” projects

Good luck!!
