Ink refill?
 

Does anyone know where I can buy a ink refill kit for a HP cartridge?
I used to use the Jet-Tec brand from Staples and it worked very well but they stopped carrying them....

Try Island Inkjet. There are several locations around town. Check their website for details.

i did not get a refill kit, but i just went to a place in richmond called http://www.vita.ca to buy non-oem HP cartridges at a much lower price... i just installed them into my ink-sucking HP injet. i will report back after i get some use out of it.

I think these guys have stores inside most Walmarts.

I've been using 123Inkcartridges.ca for the last little while. They're fairly cheap and quality isn't too bad. (I suspect they sell the same generic cartridges as everyone else) The only complaint I've had with them (well, not just with them but the generic inks) is that the pigment based ink (the PGI-5BK in my case) seems to clog very easily compared to the OEM ones (Canon in my case)

In any case, it's still cheaper to toss the cartridge and get a new generic than to buy an OEM one.

One thing you might want to make sure is to check whether you use chipped cartridges. A non OEM replacement may not come with a chip. I know with the Canon's you can ignore/bypass the low ink warning, or (like I did) buy a chip resetter to reset the chip so it reports as full again.
