Title: Perfecting printer
Inventor: KOBAYASHI MASAKI
IPC: G06F3/12
Filed: 2001-03-07
Abstract: PROBLEM TO BE SOLVED: To reduce the occurrence frequency of bad print quality on the surface being printed later in perfecting print. SOLUTION: When an operator transmits print data of perfecting print from a host apparatus to a printer, a data receiving means on the printer side receives that data and passes it to a data analyzing/executing means. The data analyzing/executing means writes surface page data in a surface image memory and rear surface image data in a rear surface image memory and then delivers a print start command to a perfecting print control means. In response to the print start command, the perfecting print control means counts the number of ON dots in the surface image memory and the number of ON dots in the rear surface image memory, makes a decision that the surface having a smaller number of ON dots is printed first and controls the operation to print that surface first and the other surface next.
