My Dad would have said it's to make little girls ask questions.

I'm good with going to BUY paper, but I've got stacks of paper that is unidentified, no more wrappers. So as long as I don't try to feed it flimsy typing paper from back in the day, anything the same thickness as the 20 weight paper I buy cheapo is okay? No difference between mimeo paper, printer paper, etc.?

I've had Old Betsy, my HP Deskjet 940c for a loooooong time, and I like her. They don't make 'em like her anymore. I have ink on hand worth more than I paid for Old Betsy.
