I just go to Staples and hand them back in for their bucks.
As to fade proof. Isn't that fade "resistant"? I'm seen claims of fade proof but after putting such in the Arizona desert sun for 5 years it did fade.
Also, the paper matters too. But you can research more about low acid or acid free/neutralized papers.
Epson has had archival priter ink for several years. I find that they will not recycle used cartridges w/o a $5 - $10 fee! (outrageous) Anyway, HP seems to have a fairly fade proof ink but I can't get "Vivera" ink for my printer. I use a Photosmart C5580 and use 75XL and 74XL. Has anyone an opinion on the ink and it's permanance? Have you found the color to be fade proof???
