Abstract: After document data have been inputted by operating character keys, if an automatic setting key is operated to allow the print character size to be set automatically and a print key is then operated, printing process control is executed and the greatest character size printable on a tape mounted in the tape printing apparatus is set (S33), a base line position shifting process is performed so that the character is positioned around the center of the width of the tape (S34). Then, dot image data in the print character size that is set on the basis of the document data is generated (S31) and the dot image data is output to the printing mechanism to be printed on the tape (S32).

Abstract: When a label name is selected, a plurality of prompt associated with the selected label name are displayed one after the other on a display so that a user can easily know what text data needs to be inputted. The text memory stores text data inputted as prompted by each of the plurality of prompts associated with the selected label name. Also the text memory retrieves, from a registration layout information memory, print layout information for printing the inputted text data. The print mechanism prints the text data stored in the text memory on a tape based on the print layout information. In this way, a label printed with the text data, that can be adhered to the binding of files and the like, can be produced quickly and easily.

Abstract: When an enlargement print key is pressed, a label producing apparatus enters a mode for setting the enlargement magnification used for enlargement printing. Next, a number key is operated to actually set the enlargement magnification. After the creation of print image data, respective data are taken from a table in which the respective data about widths of printing tapes, the number of printing tape segments based on width of tape and enlargement magnification, and "an enlargement start bit position," "an enlargement end bit position," "an enlargement work start bit position 1," "an enlargement work start bit position 2" and "the number of shifts for adjustment" with respect to each tape width which have been specified to thereby create one-dot string data. When it is desired, for example, to scale up and print data associated with a 12-mm tape width in 3.times. magnification, the enlargement print data is printed on the corresponding printing tape by being divided into three at 12-mm width intervals.

Abstract: When a character key is operated, the apparatus reads display character size data for the inputted character, which corresponds to a selected print character size, in S40. Display dot pattern data corresponding to the starting character code in a text memory is then read out. The thus read out data is stored in the location designated by a display position pointer value of a display data buffer in S42. The print fullwidth data for the inputted character code is then read out in S43 so as to calculate the display fullwidth data for display in S44. The display fullwidth data is added to the display position pointer value to determine the next display position pointer value in S45. The display dot pattern data corresponding to the next character code is placed into the location designated by the next display position pointer value in S42.

Abstract: After initialization (S1), the cassette signal is retrieved (S2). Then the tape width of the tape in the tape cassette mounted in the tape printer is determined by tape TB1 (S4). The width of the image display zone is calculated using the tape width and using the table TB5 (S7). The data of standard format information is stored in the start address of the text memory (S8). A text input screen is displayed set with the image display zone corresponding to the tape width calculated in S2 for the display. A cursor is also displayed having the size of the display character size, which was determined based on the print character size, which has been calculated using the tape width, the number of lines "1," and the table TB3. Accordingly, it is possible to provide a grasp of the relation between tape width and the situation at which characters will be printed.

Abstract: In a tape printing device, pressing the print execution key when print data and size data are stored on the memory causes the tape printing device to perform a calculation to obtain the total character height based on the number of print lines L and the vertical size of the print image. The tape printing device further performs a calculation to obtain the total blank space width based on the total height and the print allowance area and distributes the total width into the upper blank space width, the lower blank space width and the blank space width between the print lines based on the result of the calculation. The blank spaces are positioned according to the blank widths. The dot pattern data is spread along the base lines and positioned in the process.

Abstract: A character string and data characters for printing a bar code are first input, and a print key is operated. When the data read from a text memory of the apparatus are character data, the apparatus creates dot pattern data for printing the character string as per the character size selected. When bar code starting data are read, the data following the characters are read out and converted into bar code data. After the data representing a left-hand side margin of the bar code are generated, dot pattern data constituting the bar code are created in accordance with the height of the character size selected. Then, a right-hand side margin of the bar code is generated.

Abstract: A tape printer in which, if prior to printing, a scale print key is operated, a scale data setting process is carried out to input and establish a plurality of setting data about the scale length, pitch and other print conditions. The scale data setting process is followed by a scale printing process executed in accordance with the setting data. This permits printing of a scale having the designated length and pitch onto the printing tape to include those to which a scaling factor has been applied.

Abstract: When a tape cassette having a special tape, such as a lettering tape, is mounted into a tape printing device, which normally permits user set margins, for printing image data on a tape by driving a thermal head and a tape feed motor until all image data is printed out, the user set margin is disregarded and the tape is automatically fed for predetermined amount for setting a predetermined rear margin behind the print end portion. The tape is then automatically fed further for the same amount prior cutting the tape, at the rear end of the margin by driving a tape cutter mechanism. Thus, a rear margin is provided for the cut tape and a front margin established before the next print start portion. The amount the tape is fed is an amount that is long enough to hold the lettering tape when an image printed on the tape is transferred onto the image receiving medium.

Abstract: A tape printer includes a thermal head (13) fixedly mounted on a frame (2) wherein the thermal head (13) prints character strings on a tape (5) uni-directionally moving past the thermal head (13). A keyboard (3) is provided for entering characters and data regarding a number of print lines. Character code data corresponding to the entered characters are temporarily stored in line buffer (41), and the thermal head (13 ) prints the character strings in a plurality of lines on the tape (5) based on the character code data and print line number data. Each of the plurality of print lines can be enhanced on a line basis with one of flush left, centering, flush right, and justification. When at least one of the plurality of lines is to be enhanced, the longest character string contained in one line is identified and the rest of the lines are printed in relevant positions referring to the print position of the longest character string.

Abstract: The document data of a plurality of blocks are input and an auto size is set. After this, when a print key is operated, the data concerning the width of a tape is read out by a cassette distinction sensor. Then, the block number is calculated based on the document data stored in the text memory, and further, the linage of the first block is calculated. The print size is calculated based on the size table corresponding to the tape width data and the linage to be printed. The base line position of each print line is calculated based on the print size, the document data, the tape width data and the linage. The dot pattern data in each line which is formed based on the print size and the document data is developed into the print buffer based on the base line position. When the processing in each block is completed, the print processing is executed. Thus, various blocks of print on the tape may be set to different sizes.

Abstract: A bar code printer capable of printing bar codes simultaneously with character strings made of, for example, alphanumeric characters. Operating a bar code key causes a bar code input display to appear on a display and the bar code start code to be stored in a bar code buffer. Then operating a number key causes a number code representing the number to be stored in the bar code buffer and a dot pattern representing the number code to be output to a video RAM. Operating an execution key while a 13 digit number code is stored in the bar code buffer will additionally cause an end code to be stored in the bar code buffer and the resultant code string to be stored in a text memory.

Abstract: An operator inputs characters from a keyboard. The characters are stored in the form of character codes. The operator sets an overall frame and a partial frame to decide characters to be enclosed in the frames by editing character codes symbolically displayed on the liquid crystal display. In this process, both ends of the frames are also encoded into character codes. After the operator enters an execution key, the character codes are converted into bit image data by means of a character generator. The image data for characters, the overall frame and the partial frame are combined on the image buffer. When the image data is ready, the image data is transferred to the thermal head via a driving circuit, and the printing process is executed on a printing medium. An array of printing mechanisms substantially extending across the width of the tape printing medium allow the printing device to execute the whole printing process while sending the medium in one direction.

Abstract: A printing device, which is capable of printing image onto a tape-type recording medium along the longitudinal direction of the tape-type recording medium, is also capable of printing the image on the tape-type recording medium in a rotated fashion with respect to the longitudinal direction of the tape-type recording medium. When the image is printed with a certain rotation, it is discriminated whether a length of the image to be printed in the rotated fashion in the width direction of the tape-type recording medium is smaller than the width of the tape-type recording medium. Then the size of the image to be printed is reduced if the length of the image is greater than or equal to the width of the tape-type recording medium.

Abstract: After an operator inputs text data and presses the print execution key, a console for setting the size of characters appears on the display. Setting auto-mode in this step initiates the process of data examination. If the whole text consists of code data for capital alphabets and numerals, the control unit calculates the magnification power Q for magnifying original characters to maximum characters, and the printing device prints the text in maximum size.

The printing machine compensates for different line type faces and/or a different type-face layouts between heads. The print drive unit selectively moves one type face on the printing head to a predetermined position above a print paper and prints the character on the paper. The mode setting unit serves to set a mode associated with the printing head in use. The data supplying unit holds data about printing, including line data.

Abstract: In a printing device for printing bar-codes, a string of characters and symbols representing the contents of the bar-codes are printed under the bar-codes by replacing the lower part of the dot pattern with the dot pattern for the string. The present invention is characterized in that the printing device has a decision means for deciding whether or not to print characters and for printing bar-codes with a sufficient height for reading operation by bar-code readers. The printing device automatically omits the string of characters when a character size set by an operator is not large enough to print a string and a bar-code in juxtaposition.

Abstract: The data processing apparatus comprises a line counter for counting total number of output lines while outputting ruled lines, characters, and symbols and a input data memory for storing the data of characters, symbols, and ruled lines input corresponding to the output position of each page. The vertical ruled line data output to the final line of the page under outputting, the horizontal ruled line data which touches this vertical ruled line, and the vertical ruled line data output to the first line of the next page are searched based on the data of the line counter and the input data memory. And, when the horizontal ruled line data is searched in the final line of the page and the vertical ruled line data is searched in the final line of the page and the vertical ruled line data is searched in the first line of the next page, the horizontal ruled line which corresponds to the horizontal ruled line data of the final line of the page is output to the first line of the next page.
