Abstract

PURPOSE:To enable quick setting of a printing range corresponding to a paper width by providing an indicator lamp which detects and indicates the presence of printing paper by using a sensor when a printing head moves to the left and right ends of the printing range. CONSTITUTION:A printing head 1 is equipped with a sensor 2 for detecting a paper end, and if a command for setting a left margin width is transmitted to a printer from a host device after loading paper on the platen 1 of the printer, the printing head 1 moves to a specified position while performing a spacing action. Then the sensor 2 detects the presence of printing paper where the printing head stops. After this, if the printing paper is not present, a PE lamp on an operating panel 3 is caused to flash and thereby warns an erroneous setting value of left margin width. Also when the right margin width is set, the printing head is likewise moved to the right and detects the presence of printing paper using the sensor 2. Consequently, the printing width corresponding to the paper width can be quickly set.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a serial printer that prints by mounting printing paper on a platen.

In a serial printer configured to attach print paper to a platen and print on the print paper, conventionally, when setting the print range, a paper corresponding to the data sent from the host device is used, and the paper is The operator is setting the printing device appropriately within the width.

Therefore, conventional serial printers have the disadvantage that if printing is performed using printing paper whose width is narrower than a predetermined printing range, the print data will protrude outside the paper and be printed on the platen.

In FIG. 1, 1 is a print head, and 2 is a sensor provided on this print head 1 to detect the edge of the paper. In the serial printer configured as described above, after the operator loads paper onto the printer's platen 1, when a left margin width setting command is sent from the host device to the printer, print head 1 is specified. It moves to a position by performing a spacing operation, and at that position, the sensor 2 detects the presence or absence of printing paper. As a result of this detection operation, if it is found that there is no printing paper, the PE lamp 4 on the operation panel 3 as shown in FIG.
blinks to notify the operator that the left margin width setting is incorrect. FIG. 2 is a waveform diagram showing the blinking state of such a PE lamp. When setting the light margin width, the print head is similarly moved to the right and the sensor 2 detects the presence or absence of print paper.

As explained above, the serial printer of the present invention detects the edge of the print paper using a sensor installed in the print head, and when the left margin and right margin settings are inappropriate, the lamp on the operation panel is activated. Since the operator can be notified by blinking, the operator can quickly set the printing range that matches the width of the paper.
