Abstract: The position of a print head, movable back and forth over the width of a paper band, is used as an index versus parameter data in menu presentation recorded parallel to the extension of the print-head motion path in a device for the setting of operating parameters of a printer. In order to eliminate a conventional continuous and repeated printing of the operating parameters on paper, a new setting of the programming at the printer can be performed such that the operating parameters (3) are visually displayed in form of a permanent or callable display (4) at the casing (5) of the printer. A position-determining element (6) is furnished at the print head (1). The momentary position indicator (7) of the print head (1) is reproduced on the display (4) for the operating parameters (3), as illustrated in FIG. 4.
