My best advice was to get a printer that can do what you need to have done. Since there are likely to be several models that meet the criteria, I also use this tie-breaker:

Are toner refill kits for the proposed printer available on eBay or can you buy them on eCrater? They way I see it, if you can buy a refill kit it’s like you are making money by not paying lots of cash for the overpriced ones the manufacturers sell.

If they’re not available, don’t buy it!
