Abstract: A printer includes a recording unit, a glue belt, a pressing roller, a blowing unit, an ion application unit, and a charging unit. The glue belt includes an outer peripheral surface configured to support a medium. The pressing roller is provided upstream of the recording unit in a circumferential direction, and presses the medium against the outer peripheral surface. The blowing unit is provided upstream of the recording unit and downstream of the pressing roller in the circumferential direction and configured to blow a gas toward the outer peripheral surface. The ion application unit applies ions having a positive polarity to the gas blown onto the outer peripheral surface. The charging unit charges a front surface configured to come into contact with the medium so that the polarity of the potential of the front surface is the same as the polarity of the ions applied to the gas.

Abstract: A cartridge providing system includes a printer ejecting, onto a printing medium, a liquid (recording material) supplied from a cartridge, and a server managing provision of the cartridge to a plurality of users that use the printer. The server determines whether an unused stock, which is a stock that remains unused for a first period or longer, is present in a stock of cartridges held by each of the plurality of users. In a case in which it is determined that an unused stock is present in the stock held by a first user of the plurality of users, when a period until a usage expiry date of the unused stock is less than a first threshold value, the server specifies a second user, of the plurality of users, to be provided with the unused stock, based on user stock data in which the stock of cartridges held by the user is registered, and on usage amount data indicating a usage amount of the cartridge.
