摘要： In a method for operating a serial dot matrix printer having a print head that is reciprocated along a first direction and stopped for performing bi-directional printing on a medium that is moved in a second direction orthogonal to the first direction, correction amounts for correcting the bi-directional printing alignment are stored in a memory device. The desire correction amount is then selected and stored in a battery-backed-up memory. The bi-directional printing then is performed using the desired correction amount stored in the battery-backed-up memory.

摘要： An LED printer includes a printing control unit and an LED head. When a video signal received at the control unit has a higher resolution than the LED head, the control unit carries out the logical AND between successive bit data of the video signal to convert the video signal to a first signal. Corresponding to a line timing signal, this first signal is transferred as a head data signal to the LED head and is then printed on a basic raster scanning line. Further, the control unit also carries out the exclusive-OR between the successive bit data of the video signal so that the video signal is converted to a second signal and outputted to a line buffer. Corresponding to an additional line timing signal, the second signal is transferred as another head data signal to the LED head and is printed on an additional raster scanning line. The LED head drive energy for performing printing along the basic raster scanning line is set independently.

摘要： A method for printing an image including the step of generating a basic line timing signal and an additional line timing signal providing timings between respective timings of the basic line timing signal, producing a matrix by a video signal of a number of lines corresponding to a ratio of a resolution of the video signal to a resolution of a printing portion, producing one dot of a grayscale data signal having grayscale information of dots of the matrix, and driving a printing head by head drive energy determined according to the grayscale data signal, when an image is printed by using the printing head having a resolution in the raster direction less than the resolution of the video signal for forming the image to be printed. Although a number of dots for forming the image is reduced, amount of information is not reduced since dot information is converted into the grayscale information, so that high-quality printing is possible at a time of printing for grayscale.

摘要： According to a method of adjusting a head gap, a wire dot head is set to a predetermined position of a reference head gap; a printing pattern for detecting printing time is printed by a plurality of pins; reference printing times of respective pins are detected. Next, a test printing is performed with test printing dots previously selected from printing data, and printing time of the test printing is detected. Then, the thickness of the printing media is calculated based on the reference printing time and the printing time of the test printing. At that time, a rule of thumb in which the difference of the printing time corresponds to the difference of the head gap, is used. Then, a shift amount of the wire dot head is calculated for setting the head gap to an optimum value according to the thickness of the printing media, and gap shifting mechanism shifts the wire dot head by the shift amount. This leads to highly accurate detection of the head gap and improves printing quality thereof.

摘要： Bit data of a received video signal is partially converted into a first signal representing a data sequence corresponding to the resolution of an LED head. The remaining bit data of the received video signal, which are not converted into the first signal are converted into a second signal representing another data sequence corresponding to the resolution of an LED head. The LED head includes a resolution conversion circuit which converts the video data into the first signal and the second signal. The signals are stored in a shift register having a plurality of line buffers. The first signal is printed on a basic raster line and the second signal is printed on an additional raster line. An LED head drive energy with which basic raster lines are printed and another LED head drive energy with which additional raster lines are printed are set independently of each other.
