"Using knockoff cartridges, are we?"
Nope. I am with HP's Instant Ink (pretty inexpensive and can print whatever you want within the page limits and they'll roll over some of the unused pages).
The print quality on best to coated photo paper is pretty good for a cheap'n'cheerful printer.
The print quality on normal to plain A4 is, on the other hand, barely better than my ancient DJ500 from the '90s. Plenty of visible streaks due to uneven ink dispersion, misalignments (even after being aligned) and generally like something that belongs in the last century. Millions spent on ink technology? Great. How about dropping some cash on print head technology? Or failing that, just beg Brother for their secret method, as none of my recent printers (a Canon and the HP) could hold a candle to my old Brother 165C. Now that is a printer that made good results on a piece of plain paper.
