Don wants to know if there's a Bluetooth printer that he can use with a friend's Samsung Galaxy Tab 10 tablet. Leo says that there are, but another option from Google is Google Cloud Print, which prints from any internet connected printer anywhere in the world. So if he can get on Wi-Fi, he can print.
If the retirement center won't let him do that, Canon Pixma printers are Bluetooth, and HP makes some as well. The issue may be the tablet more than the printer, though. Don will need to find a printer that supports the tablet in question. Samsung also has a feature called Samsung Mobile Print, which works through an app. It can then print to any printer. So he should try that first.
