Q: Looking for recommendations re: printers and CD burners for my late 2014 Mac Mini.

For CD/DVD/BluRay optical drives see:

For printers, it all depends upon your use and budget. Just get a Mac-compatible printer (most are) that mmets you needs and budget.

Color or only black and white?

USB? Network? Wofof?

If B&W then you can get a laser multifunction printer.

Inject ones can cost less initially but ink costs and dries out if you do not use it often.

I have an USB Brother B&W laser printer which is only printer.

I also have an wifi/network Epson Work Force 845 inkjet multifunction printer which I really one use for scanning.

Actually, pretty much any USB CD/DVD drive will work.  Stick

with name brand products from LG, Samsung, Sony, etc.  Some

very cheap "off brands" may work but won't last.

Personally, I would stick with some HP all-in-one.  Although Canon and

Epson are very good printers, it seems HP maintains OS support longer

for their printers than the others.

HP is making at least some of their ink cartridges proprietary, preventing you from using third-party inks.
