PCT No. PCT/DE94/00273 Sec. 371 Date Sep. 20, 1995 Sec. 102(e) Date Sep. 20, 1995 PCT Filed Mar. 11, 1994 PCT Pub. No. WO94/21466 PCT Pub. Date Sep. 29, 1994A recording substrate (21) is brought into a predetermined position on a recording substrate holder (10). One edge of the recording substrate (21) rests against a recording substrate stop (18) provided at one side on the recording substrate holder (10). Extending transversely to the recording substrate stop (18), in or on the recording substrate holder (10), there is a transmitting or receiving means (KS) which can be covered by the recording substrate (21). A receiving or transmitting means (KE) is provided on the printing head (7). In the region of the extent of the transmitting or recording means (KS), at a defined distance from the recording substrate stop (18), a shielding surface (30) is arranged on the recording substrate holder (10). During the movement of the printing head (7) along the transmitting or receiving means (KS), the location of the shielding surface (30) and the location of the recording substrate edge remote from the recording substrate stop (18) are detected.
