I thank you for your responses. I have since learned that £46 (not £49; I should always doublecheck) was actually a little low to pay this Mr. Paxton for paper, ink, and parchment. To put it in perspective, there is a case where Robert White was paid 18s to print three reams worth of a pamphlet. On the other end, John Crouch (of the Man in the Moon) claimed that one penny was just enough to pay for paper and ink (which works out to 216 sheets for 18s). Obviously, there is some discrepancy. £46 seems excessive, but the fact that Paxton received more (for periods of several months up to almost a year) on occasions would indicate more of a prodigious use of paper than anything else.
