In the practice of the system herein, there are prepared three image areas for printing two associated, but different business formats utilizing one photographic negative containing peculiar information common to both of the formats. A first image area is provided with information relating to one of the formats, a second image area is provided with information related to the other format, and the third image area prepared from the negative is provided with the peculiar information common to both formats. The printing apparatus contains a roll made of a continuous strip of inexpensive paper, and a stack support on which are alternately placed two stacks of sheets on which the two business forms are to be printed. Means are provided for separately feeding the sheets and portions of the continuous strip to the printing station. During the continuous printing operation one of the forms is initially printed using only the first and third image areas to provide composite impressions that are applied to one stack of sheets. When the feed of sheets from such one stack is stopped, the feed of the continuous strip is started, and the machine run for a number of cycles to clean the ink from the first image area and the information from such first image area on the blanket, and simultaneously to build up the proper degree of ink on the second image area, and the information from such second image area applied to the blanket, while continuing the inking of the third image area. The feed of the continuous strip is then stopped, and the feed of the second stack of sheets is started, so that they are provided with a composite impression of the second and third image areas. The photographic negative is then packaged with the completed order of sheets, so that when it is necessary to reorder the same, all that is need done is to forward the negative to the printer.
