Gorham:
These cartridges are not compatible with the original photosmart printer (you mean the big white one that is not very tall and came out in late '98 or early '99 right?). That one takes the "moon and star" cartridges, AKA the "orange and purple" cartridges, or as they are known by HP the #845 and #844 cartridges. Those cartridges are very hard to find, that printer seems to be the worst supported printer in HP history (even worse than the 2000C). Sorry about the bad news pal.

I think the reason that most people do not refill their carts is because the initial refill is a bit daunting. I get customers tell me all the time that when they first refilled their cartridge they made a mess, it did not vacuum correctly, it leaked, etc... and I think that scars them for life. I dunno, just a theory of mine. If you can save money and still get GOOD quality prints out of your cartridges, then more power to you. I still have 2 #45 cartridges from the Rite-Aid "Buy 1 Get 1 Free" promo some time ago, so I will not have an opportunity to refill anytime soon.
Thanks for the advice,
Good heads-up on a good deal !
