Ink Cartridge anger! Grrr!

Hey! Gonna try to post some pics. I have a memory card reader in my printer, so I have been just reading it & saving pics on my computer, then uploading to the blog. Apparently it's not working without the EMPTY black cartridge in it:( I went to Walmart & Staples to find ink for it, but no luck:( Then, I took my empty cartridge to Walgreens to see if they could fill it, but this printer is too new - they can only fill the older ones?!? Grrr! Anyway, I'm going to see what I can find on Ebay, otherwise I'll have to special order it or something. You would think they would have it at Staples were I bought the printer in Feb or March!
