Replace the head about every three months and or sooner if bristles splay or feel scratchy, especially with tight contacts or a retainer. Even if it looks fine at three months, the tips fatigue and a fresh head cleans better.

I would look for an inkjet that uses cartridges with the print head built into each cartridge. If it ever clogs after sitting swapping the cartridge refreshes the nozzles and you are back in business. Leave it plugged in so it can do its light self maintenance, since cutting power can skip that. Pigment black is best for crisp coupon text and barcodes, and running a tiny nozzle check once a month keeps things happy. For coupons, bright white 24 lb inkjet or multipurpose around 96 to 98 brightness feeds smoothly and looks clean. 28 lb works if your printer supports it through a rear feed, but skip card stock. No drama.
