Sheet pack and printer

1. Field of the Invention Disclosed are a sheet pack and a printer, the sheet pack being inexpensive and capable of being easily set onto the printer and simply exchanged with another one, while users can know information such as the quality, size and number of sheets of printing paper contained in the sheet pack. The sheet pack, containing a predetermined number of sheets, has a frame case formed of thick paper, and may include a sheet supply opening, an abutment opening, a pressure contact opening and a separating pad. A recording member for recording information such as quality, size, number, thickness, color or production date of sheets contained in the sheet pack, may also be provided on the sheet pack. The printer, onto which the sheet pack can be removably set includes an information reading unit for reading the information recorded in the recording member when the sheet pack is set onto the printer. The information read by the information reading unit is displayed by a display unit. The number of sheets remained in the sheet pack resulted from subtracting the number of sheets printed from the original number of sheets may also be recorded in the recording member.
