Can't find my manual for canon p23-dh iii. where on the calculator, and how, do you remove the old ink to insert new one?

Use CP 13 ink roller 2pk or larger. You just pull out the old one and pop the new one in its place. If you look under product description on the web page it lists your P23 dh III.

Is this brand lasting longer than the Porelon brand?

This is a quality product but I don't use the calculator enough to be able to determine how long it lasts compared to another brand

Will this ink work on a canon p23-dh ii?

Yes it should work in that model
