This paper is a 90gsm which I think is great for EcoTank 2800 as 90gsm is the max you can tell the difference in thickness between this and normal 20lbs (75gsm) paper. Also works great in the Laser printers too.
I sometimes check for office supplies at WalMart since I am already there for groceries. That is a lost cause. At Staples I got paper that works well for the laser printer I now have. This week I got good quality long white mailing envelopes and an excellent full-sized lined notepad with holes already punched. And someone is always available to point me or take me to what I'm looking for. Great service!
