How can I print logos in pens and others promotional items (plastic). Which printer can I use to do the job?

I need to print logos in promotional items like pens, plastic cards, Key chains, and a large variety of plastic based products with different sizes and shapes. How can I do that?? Which printer can I use?? How the process is done??

Thank you in advance…

you can’t print it yourself.

find any business whose primary purpose is this (printing logos and names on plastic products).

find a low cost one, it will work for you.
