Printer with a duplex printing capability

A printer with a duplex printing capability, comprising:

• a printing section comprising a print drum around which a master formed with a first and a second image side by side is to be wrapped and a press roller selectively movable into or out of contact with said print drum;
• a sheet feeding section for feeding a sheet toward said printing section;
• a sheet discharging section for discharging a printed sheet coming out of said printing section to an outside of said printer;
• an auxiliary tray for temporarily stopping the printed sheet carrying an image on a front side thereof;
• refeeding means for again feeding the printed sheet temporarily stopped by said auxiliary tray toward said printing section;
• and
• a path selector for selectively steering the sheet coming out of said printing section toward said auxiliary tray or said sheet discharging section;
• wherein in a duplex print mode said printing section prints either one of the first image and the second image on a front side of a first sheet fed from said sheet feeding section, said path selector steers said first sheet coming out of said printing section toward said auxiliary tray, said printing section prints either one of said first image and said second image on a front side of a second sheet fed from said sheet feeding section while said refeeding means again feeds said first sheet to said printing section to thereby form either one of said first image and said second image on a reverse side of said first sheet, and said path selector steers said first sheet toward said sheet discharging section and steers said second sheet toward said auxiliary tray.
