Printing system, printer client and service server system

A printing system, comprising:

• a service server system from which data is downloaded and further comprising:
• a) a means for certifying a login request from a printer client;
• b) a means for specifying abstract data, allowed to be transmitted to said printer client, in accordance with a copyright protection level of said printer client;
• and
• said printer client for conducting image output in accordance with said data and further comprising;
• a) a means for generating a login request to said service server system;
• b) a means for specifying desired abstract data and for notifying download request of said desired abstract data to said service server system;
• c) a means for downloading transmission form data, generated by an encryption process based on said desired abstract data, from said service server system;
• and
• d) a means for decrypting said transmission form data and conducts image output of said desired abstract data.

A printer client for conducting image output in accordance with data, downloaded form a service server system, further comprising;

• a means for generating a login request to said service server system;
• a means for specifying desired abstract data and for notifying download request of said desired abstract data to said service server system;
• a means for downloading transmission form data, generated by an encryption processing based on said desired abstract data, from said service server system;
• and
• a means for decrypting said transmission form data and conducts image output of said desired abstract data.

A service server system from which data is downloaded and further comprising:

• a means for certifying a login request from a printer client;
• a means for specifying abstract data, allowed to be transmitted to said printer client, in accordance with a copyright protection level of said printer client;
• and
• a means for controlling said printer client so as to download transmission form data, generated by an encryption process based on said abstract data.

A printing system, comprising:

• a printer client for conducting image output in accordance with data, downloaded from a service server system, and further comprising:
• a) a decrypting means for decrypting encrypted abstract data so as to obtain abstract data;
• b) an outputting means for conducting image output of said abstract data;
• and
• c) a protecting means for protecting said abstract data in a transmission path, from said decrypting means to said outputting means, against outside access;
• said service server system from which said data is downloaded and further comprising:
• a) a comparison table in which a copyright protection level of said printer client, established stepwise in accordance with said protecting means, is stored in relation to a copyright protection level of said abstract data, established stepwise in accordance with difficulty of decryption of said abstract data;
• b) a specifying means for specifying said abstract data, to be transmitted to said printer client, by referring said comparison table for said abstract data in accordance with said copyright protection level of said printer client;
• and
• c) an encrypting means for encrypting said abstract data so as to generate said encrypted abstract data;
• wherein said service server system obtains information for specifying said printer client from said printer client requesting access to said service server system so as to specify and encrypt said abstract data;
• and said printer client downloads said abstract data, specified and encrypted by said service server system, so as to conduct decryption and image output of said abstract data.
