ABSTRACT:
The invention is a document printing aid for microcomputer printers. The invention includes a flexible mask of material, larger than the document to be printed, with an outline of the document on the face of the mask. The printing aid is inserted into a microcomputer printer. The document is placed behind the printing aid and is aligned with the outline. The document, held between the printing aid and roller, is positioned for printing. Apertures in the printing aid allow the printing element to contact the document.
