PCT No. PCT / CH95 / 00223 Sec. 371 Date Apr. 2, 1997 Sec. 102(e) Date Apr. 2, 1997 PCT Filed Oct. 3, 1995 PCT Pub. No. WO96 / 10881 PCT Pub. Date Apr. 11, 1996A printer /
scanner unit includes a
scanner for optically reading a
document model and a printer to print a recording medium. The
document model is transported along a transport path from a feed device to an
output device of a transport device. After the scanning step, the
document model is displayed on a screen and can be completed there with
supplementary data, supplied, for example, by means of a
data input device, such as a keyboard or a
data memory. A document model which has been scanned askew, for example, can be shifted to a position which has been defined for completion with
supplementary data, and can possibly be altered in size. It is foreseen that then only the data with which the document model on the screen is to be completed are transmitted to the printer, and the
supplementary data are printed on the original of the document model, which was previously scanned. For that purpose, the data must be converted with transformation parameters, which the computer has obtained from the aforementioned shift of the scanned model into the defined position. The device is particularly suitable for
filling in original, pre-printed forms or completing them with other data.
