Abstract
In response to detecting that a remaining supply of print material of a first cartridge has reached a first threshold, a printing device transmits a request. In response to detecting that a second cartridge has replaced the first cartridge, the printing device determines whether the remaining supply had reached a second threshold and whether a token permitting usage of the second cartridge was received responsive to the request. In response to determining that the remaining supply had reached the second threshold and that the token was received, the printing device prints with print material from the second cartridge.
