Claim:
1. An ink jetting digital printing apparatus supporting double-side printing, characterized in comprising: a first sprayer module and a corresponding first group of color plane control servers, a second sprayer module and a corresponding second group of color plane control servers, a rasterization image processing server, and a system control server; wherein the first sprayer module and the second sprayer module comprise a group of sprayers of the same two or more colors respectively; the first group of color plane control servers comprise color plane control servers in one-to-one correspondence with sprayers in the first sprayer module; the second group of color plane control servers comprise color plane control servers in one-to-one correspondence with sprayers in the second sprayer module; the color plane control servers in the first group of color plane control servers are arranged in parallel with the color plane control servers in the second group of color plane control servers; the rasterization image processing server is used to perform a rasterization process on a print file of a current print job, and transmit page data obtained after the process to a corresponding group of color plane control servers; the first group of color plane control servers are used to generate complete font-side print data according to the page data received from the rasterization image processing server, and transmit the font-side print data to a corresponding first hardware control module; the first hardware control module is used to control the first sprayer module according to the complete font-side print data to complete the printing of the font-side print data; the second group of color plane control servers are used to generate complete back-side print data according to the page data received from the rasterization image processing server, and transmit the back-side print data to a corresponding second hardware control module; the second hardware control module is used to control the second sprayer module according to the complete back-side print data to complete the printing of the back-side print data; various color plane control servers of the first group of color plane control servers and various color plane control servers of the second group of color plane control servers are further used to transmit print progress information to a system control server; and the system control server is used to, according to the print progress information of the various color plane control servers, calculate a number of pages that have been printed in the current print iob and display the page number information on a user interface.
