Printing System and Printing Device

Abstract

A first printer 60 has a connection unit to which data is input and which outputs print data based on the input data; a first printer print unit 71 that prints; a detection unit 62 B that detects if the input printing result contains an error when the printing result of the print data output from the connection unit is input; a reprint storage unit 65 A that stores print data when the detection unit 62 B detects an error; and a reprint control unit 62 F that outputs print data stored in the reprint storage unit 65 A from the connection unit when a predetermined specific condition is met.

What is claimed is: 
     
         1 . A printing system comprising:
 a host device configured to transmit data;   a first printing device including
 a connection unit configured to receive the data transmitted by the host device and to transmit the data, and 
 a first print unit configured to print; and 
   a second printing device including
 a second print unit configured to receive the data transmitted by the connection unit of the first printing device and to print based on the data, and 
 an output unit configured to send a printing result by the second printing device to the connection unit of the first printing device. 
   
     
     
         2 . The printing system described in  claim 1 , wherein
 the first printing device includes
 a detection unit configured to detect if the printing result of the second printing device received by the connection unit is an error, and 
 a storage unit configured to store the data transmitted to the second printing device. 
   
     
     
         3 . The printing system described in  claim 2 , wherein
 the first printing device includes a control unit configured to determine if a predetermined specific condition is met.   
     
     
         4 . The printing system described in  claim 2 , wherein
 the control unit sends the data stored in the storage unit to the second printing device when the specific condition is met; and   the second printing device prints based on the data transmitted as controlled by the control unit.   
     
     
         5 . The printing system described in  claim 2 , wherein
 the first printing device generates print data based on the data transmitted by the host device, and sends the generated print data by the connection unit to the second printing device.   
     
     
         6 . The printing system described in  claim 3 , further comprising :
 a data input device connected to the host device, configured to acquire identification information, wherein   the data transmitted by the host device includes the identification information acquired by the data input device; and   the control unit determines that the specific condition is met when the host device transmits second data different from the data, and the identification information contained in the second data received by the connection unit matches the identification information contained in the data.   
     
     
         7 . The printing system described in  claim 6 , wherein
 when the identification information contained in the second data matches the identification information contained in the data, the first printing device sends the data and the second data to the second printing device; and   the second printing device prints based on the data and the second data.   
     
     
         8 . The printing system described in  claim 4 , wherein
 when the detection unit detects that the printing result is an error, the control unit of the first printing device controls printing the data stored in the storage unit of the first printing device by the first print unit.   
     
     
         9 . The printing system described in  claim 8 , wherein
 the control unit stores the data in the storage unit when the data could not be printed by the first print unit.   
     
     
         10 . The printing system described in  claim 3 , further comprising :
 a storage device connected to the first printing device;   wherein the control unit controls the connection unit to transmit the print data stored in the storage unit to the storage device.   
     
     
         11 . The printing system described in  claim 1 , wherein
 the data transmitted by the host device contains transaction information;   the first printing device includes a print data acquisition unit configured to acquire print data based on the transaction information contained in the data; and   the second print unit of the second printing device prints a coupon based on the print data transmitted by the connection unit.   
     
     
         12 . A printing device comprising:
 a connection unit configured to transmit received data and to receive a printing result for the transmitted data;   a storage unit configured to store the data;   a print unit configured to print; and   a detection unit configured to detect if the printing result received by the connection unit is an error.   
     
     
         13 . The printing device described in  claim 12 , further comprising :
 a control unit configured to determine if a predetermined specific condition is met.   
     
     
         14 . The printing device described in  claim 13 , wherein
 the control unit controls the connection unit to transmit the data stored in the storage unit when the specific condition is met.   
     
     
         15 . The printing device described in  claim 14 , wherein
 the connection unit transmits the data stored in the storage unit.   
     
     
         16 . The printing device described in  claim 13 , wherein
 the control unit includes a print data acquisition unit configured to acquire print data based on the transaction information when the data contains transaction information.
