A 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.
A device for scanning a first image on a document surface and printing a second image on the document surface comprising a mechanism operable to engage a document and drive the document along a feed path, a scanner apparatus operable to generate a scanned image of the first image on the document surface as the document is driven past the scanner apparatus during a first document traversal of the feed path, and a printer apparatus operable to print the second image on the document surface as the document is driven past the printer apparatus during the traversal of the document through the feed path is provided.
An image transfer apparatus for transferring an image on a sheet medium having a frame and a reader connected to the frame for reading the image on the sheet medium. The image moves relative to the reader in a process direction when the reader reads the image. A positioning system is connected to the frame for positioning the sheet medium at a predetermined skew angle relative to the process direction.
