Re: 3100 cn print to photo paper
I found my own answer on www2.hp.com. The paper specification 106-163 g/m2 refers to paper weight.
120g/m2 equals 32-pound bond paper
160g/m2 equals 42-pound bond paper
Once paper gets over 24 pound its must be some specility paper (Photo) based on the printer requirements. 100 pound bond paper is card stock. SO look closely at the printer properties.
I did not know there was that much difference on laser paper requirements.
