Abstract

PURPOSE:To enable open face characters to be printed through reusing a used ink film, by a system wherein after normal printing is finished, an ink film is fed backward in response to an open face character printing command, and transfer of an ink is performed for one sheet of paper. CONSTITUTION:An ink film feeding part 11 is capable of feeding an ink film both forward and backward. Whether printing data are present is discriminated, and when it is discriminated that the printing data are present, a printing operation for one line is performed, followed by paper feeding and ink film feeding. On completing a printing operation for one sheet (one page), it is discriminated whether an open face character printing switch is in an ON state or an OFF state. When an open face character printing command is present, the ink film is fed backward by a one-sheet amount, whereby it is returned to the state in which it has been used for printing the preceding sheet. The printing operation for one line, the paper feeding and the forward ink film feeding are repeated until the operations for the one sheet are completed, thereby transferring.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a printing method, and more particularly to a white character printing method in a non-impact printer.

BACKGROUND TECHNOLOGY Conventionally, this type of white character printing method performs white color printing of only designated characters by receiving a white character printing command from the host computer side. In this case, for the specified character, white characters are printed by transferring the ink to the printing medium using the unused ink film portion by square self-feeding of the ink film. For this reason, there is a drawback that the ink film that has been subjected to -reverse transfer is wound up as a used film and cannot be used again.

OBJECTS OF THE INVENTION An object of the present invention is to provide a printing method that enables printing of white characters by reusing an ink film.

Structure of the Invention According to the present invention, there is provided a printing method for a non-impact printer that performs printing by transferring ink on the surface of an ink film to a printing medium, the ink film feeding means capable of freely feeding the ink film in forward and reverse directions; and command means for generating a blank character printing command, and after normal printing for one sheet is completed, in response to the detection of the white character printing command, the ink film is sent in the reverse direction by the ink film feeding means to print one sheet forward. A printing method is obtained in which the ink film is returned to the state shown in FIG.

friend 11 Hereinafter, the present invention will be explained using the drawings.

FIG. 1 is a schematic block diagram of an embodiment of the present invention, with 10
is a control section that performs printing control according to various control data from a host device (not shown). This control section controls an ink film feeding section 11 and a printing paper feeding section 12. The ink film feeding section 11 is capable of feeding the ink film not only in the forward direction but also in the reverse direction. A command generating section 13 is provided, and has a function of generating a command to print white characters in response to an operation by an operator when white character printing is required.

FIG. 2 is a flowchart showing the operation procedure of the blocks in the embodiment of FIG. If it is determined that the print data is right based on the print data presence/absence determination ii (step 1), 1 line printing processing (step 2) is performed, and further paper feeding and ink film feeding station 1! ! ! (Step 3). here,
Determining the end of printing for one sheet (one page) (Step 4)
), the on/off state of the white character printing switch (included in the command generation section 13) provided in the printer is determined (step 5).

If the switch is turned on and a white character printing command is issued, the ink film for one sheet will be reversely fed (
Step 6) is executed, and the ink film is returned to its state one sheet before. Then, one line printing process (step 7) and paper feeding.

The film forward direction feeding process (step 8) is carried out until one sheet is finished (step 9). During this time, the ink film is transferred onto one sheet.

FIG. 2(A) shows the printing result of one sheet of normal printing, and FIG. 2(B) shows the printing result of white character printing processing based on this printing result.

Effects of the Invention As described above, according to the present invention, a function for forwarding the ink film in the forward and reverse directions is provided, and after the normal printing process is completed, the ink film is moved in the reverse direction in response to the detection of the white character printing command switch in the printer being turned on. Since printing of white characters is made possible by feeding and then ink transfer of one sheet of ink film, there is an effect that white characters can be printed by reusing the used ink film. Further, it is possible to easily print white characters only by operating a switch on the printer side, without sending white character printing commands, print data, etc. from the host device.

Claims (1)

[Claims] A printing method in a non-impact printer that performs printing by transferring ink on the surface of an ink film to a print medium, comprising an ink film feeding means that can freely feed the ink film in forward and reverse directions, and a command means that generates a white character printing command. After normal printing for one sheet is completed, in response to the detection of the white character printing command, the ink film is sent in the reverse direction by the ink film feeding means to return the ink film to the state before one sheet, and then the ink film is returned to the state before one sheet. A printing method characterized by transferring ink from all lines of one sheet to a new sheet of printing medium.
