The Staples Multipurpose paper is a "good" white and a good weight for the printing that I do. The price with rebate is also quite reasonable. It works well on my HP InkJet. It also worked well with my HP LaserJet printer.
Staples brand paper works great -- I have never experienced a problem in any way. The best part is when you can get it on one of the special weekly deals -- sometimes even for FREE; just keep checking on their specials!
It's not as thin as cheap paper -- feels like it's more substantial -- when I get Staples paper I never have a problem with it jamming in the printer. And the rewards and rebates are each to put in -- I just have to remember! Staples ink program and rewards make it a no-brainer to never go anywhere else -- and recently I tried the shop from home service iwth a coupon when I just did not have time to run to the store for file folders. I was able to find what I needed on the web site without a problem apply my rewards (they prompted me easily) and got it within just a couple days.
