One half of the owners of Teemer and Spools, the first choice printing company in Ankh-Morpork, much used for printing both the stamps for the Ankh-Morpork Post Office and the new Paper Money for the Ankh-Morpork Mint. Spools is the only one of the two who has met Moist von Lipwig, but this is made up for by the fact that Moist is speaking to the person whose name is on the door.
The name Spools is a double pun:
- A "spool" (noun) is a device around which thread, wire or paper is wound, normally a cylinder or spindle; and
- To "spool" (verb) in computing is to send a file to a queue so that it is ready to print on a printer.
