PSE 2020

I'm using a MacBookPro and need to print color stickers/labels. I have many different sizes and shapes. I'm creating them in PSE 2020 and just purchased a Brother Color Laser Printer MFC-L8900CDW. The stickers/labels don't line up and the colors are way off. I've printed directly from PSE, printed from Preview, from Brother iPrintandScan. 

Questions:

Is there anyway to do this on the above printer?

Any recommendations for a printer or software that will print them properly?

I would appreciate any input.

Thanks!!
