Some Walgreens locations do cartridge refills for $10 a pop.
There's plenty of cheap DIY refill kits on
Amazon, but IIRC on the 950/951 cartridges, they're just generic ink reservoirs and the printhead assembly is separate. That's both good and bad with third party ink.
Short term, it makes refills a lot cheaper and far easier. Long term, outfits like HP design their printheads to function optimally with a specific ink viscosity, and ink that doesn't adhere to the design specs for the printheads will clog it faster, eventually leading you to needing to replace the printhead assembly more frequently, which is going to run around $75-100 for the model printer you have. Amazing how that price point is so close to the cost of the printer itself, isn't it?
It's all about consumables and planned obsolescence with printers, that's where the money is... and inkjets are the
worst of the lot.
Here's my suggestion. You need to assess needs versus wants. Ask yourself, do you need a printer in your home at all? If yes, then do you need to
regularly print in color enough to justify spending upwards of $1500 for a color laser printer, or are most of your printing needs actually just black and white with the occasional color print?
If B&W covers most of your printing needs, pick up a sub-$100 Brother laser printer that uses the TN420/450 toner cartridge and DR420 drum fuse assembly refills, set the default print option to toner saver, and look up how to turn off the low toner alert on the machine itself (it's usually
this method) and print until you can't stand the streaks (you'll probably get two reams/~1000 pages out of the starter). Once you get to that point, buy a TN450 for under $50, and find a local place that refills and refurbishes Brother toner cartridges for cheap to have your starter cartridge refilled and retrofitted to a TN450, or
learn how to do it yourself.
For any color document printing needs, either go to FedEx Office and pay per sheet, or if it's photos, learn patience and use
AdoramaPix. Any local digital photo printers will use dye sublimation, which is okay, but not great long term - Adorama actually uses a setup that does traditional photo paper and chemical development (like with 35mm film) with digital photos, and the results are
far superior.
Going this route will be far cheaper per print long term than the cost of ownership for a color inkjet, and all your resulting physical media will be much nicer and more durable than inkjet.
