Abstract

A printing system has a host apparatus for generating print data and sending the generated print data to a printing apparatus, and the printing apparatus for printing an image on the basis of the received print data. The host apparatus has: a print data generating device for generating the print data; a print data sending device for sending the generated print data to the printing apparatus; an error information receiving device for receiving image data as error information from the printing apparatus; and an error information displaying device for displaying an image on the basis of the received image data, and the printing apparatus has: a print data receiving device for receiving the print data from the host apparatus; a print data storing device for storing the received print data; an image data generating device for generating the image data on the basis of the stored print data; a printing device for printing an image on the basis of the generated image data; an error detecting device for detecting an error in a process from receiving the print data by the print data receiving device to printing the image by the printing device; and an error information sending device for sending the stored image data at a stage where the error is detected by the error detecting device, as the error information, to the host apparatus.
