What paper is your printer printing on?
I just bought an inkjet recently, and was printing on some Copy Plus paper. Smudges a bit on it. The Paper One from Popular bookshop also smudges a bit, even though it was 80 gsm.
HP 80 gsm paper is quite good. Doesn't smudge. Don't know what they put on their paper.
The 90 gsm is spectacular. One can still see the ink glister under the light. Shiok. But ink is suppose to dry fast, though.
