Printing apparatus and printing system

A printing system comprising:

• one or a plurality of printing apparatuses that performs printing on an elongated strip-shaped base material transported in a transport direction;
• and
• a server computer including a server display unit and communicable with said printing apparatus via a network,
• wherein each of said printing apparatuses includes:
• a transport mechanism that transports said base material;
• a printing unit that records a print image by causing a recording agent to adhere to said base material;
• and
• a control unit that controls each unit in said printing apparatus,
• wherein said control unit includes:
• a printing controller that controls said transport mechanism and said printing unit, and switches between a first mode and a second mode differing from each other in a configuration of printing on said base material by said printing unit and implements the switched mode;
• a calculation processor that estimates a first non-printed amount and calculates a second non-printed amount relating to a job having been completed in said second mode, the first non-printed amount corresponding to the length of a non-printed region of said base material in said first mode, the second non-printed amount corresponding to the length of a non-printed region of said base material in said second mode and calculated on the basis of result actually measured during implementation of printing;
• and
• a communication part that transmits base material usage information having been output from said calculation processor to said server computer, the base material usage information including at least either said first non-printed amount and said second non-printed amount, or a difference between said first non-printed amount and said second non-printed amount,
• wherein said server computer includes:
• a server communication part that receives said base material usage information from said printing apparatus via said network;
• and
• a server storage part storing said base material usage information received by said server communication part, and
• wherein said server communication part is capable of transmitting said base material usage information stored in the server storage part to an external user computer via said network.
