An IC memory module 33 for storing paper-related information is embedded in a core 31 of a roll paper member 30. A control circuit 50 accesses the IC memory module 33 embedded in the core 31 of roll paper member 30 via a transmission-reception antenna 202 at a timing, for example, when a power source is turned on, the roll paper member 30 is replaced, and power source is turned off, and acquires the paper-related information. The control circuit 50 controls the printing processing by taking account of the information acquired from the IC memory module 33.

What is claimed is: 1. A printing device for printing to a roll paper, which is provided with a memory device for rewritably storing at least one of a remaining quantity of roll paper and a type of roll paper as information relating to the roll paper, said printing device comprising: a holder unit holding said roll paper; and a printing controller that determines a quantity of said roll paper to be fed for printing according to at least any one of said remaining quantity of roll paper and said type of roll paper stored in said memory device; wherein when said printing control device makes a decision that the printing processing of printing data quantity to be printed cannot be completed with said remaining quantity of said roll paper for printing, which is stored, based on said printing data quantity which has to be printed and said remaining quantity of said roll paper for printing stored in said memory device, said printing control device interrupts the printing processing and outputs a signal. 2. A printing device according to claim 1, wherein said printing controller calculates an amount of a back tension force of the roll paper reflecting said remaining quantity of said roll paper, and determines the paper feed quantity according to the calculated amount of back tension force. 3. A printing device according to claim 1, further comprising: an information input-output device for executing in a non-contact mode writing and reading of said information relating to said roll paper with respect to said memory device. 4. A printing device according to claim 1, further comprising: an information input-output device for executing in a contact mode writing and reading of said information relating to said roll paper with respect to said memory device. 5. A printing device according to claim 1, wherein said printing controller so determines the paper feed quantity as to be increased when the remaining quantity of said roll paper is large or said roll paper has good sliding properties according to said information stored in said memory device. 6. A printing device according to claim 1, wherein said type of roll paper includes sliding properties for the roll paper, and said printing controller determines the paper feed quantity according to the sliding properties. 7. A printing device according to claim 1, wherein said memory device covers at least a portion of a periphery of a core of said roll paper. 8. A roll paper printing system comprising: a roll paper for printing; a roll paper member comprising detection means for detecting a remaining quantity of said roll paper for printing, and also comprising a memory device and a printing device provided with printing control means for determining a quantity of said roll paper to be fed for printing based on said remaining quantity of roll paper that has been detected; wherein when said printing control device makes a decision that the printing processing of printing data quantity to be printed cannot be completed with said remaining quantity of said roll paper for printing, which is stored, based on said printing data quantity which has to be printed and said remaining quantity of said roll paper for printing stored in said memory device, said printing control device interrupts the printing processing and outputs a signal. 9. A printing device according to claim 8, wherein said memory device is provided on a core of said roll paper member for rewritably storing a remaining quantity of said roll paper.
