How to print characters enlarged on the printer

As this is a public information case, the full text was not included.

1 is a flow chart for explaining the operation of the method of the present invention,

2 is a block diagram of an apparatus according to the method of the present invention,

FIG. 3A is a diagram showing the memory table of the character data stored in the font ROM, and (B) is an example of the configuration of one Korean character printed in correspondence with (A).

Claims (1)

Decodes the font data (B _{7 ...} B ₀ ) in unit of byte from the font ROM (1) where the character data is stored, and the most significant bit data of the first column (C ₁ ) for all 72 dots printed in the horizontal direction. (B ₇ ) is stored in the line buffer 2, and then each column C ₂ ... 72 dots in the horizontal direction while increasing the column from the second column C ₂ to the final column C ₂₄ . Storing data in the line buffer 2 with the most significant bit data (B ₇ ) of .C ₂₄ ), and repeatedly printing the data in the line buffer 2 in the vertical direction three times, and then lowering the bit order of the font data. Repeating the above-described process while sequentially decreasing the bit data (B ₀ ) to enlarge and print the character data for the first byte of each column (C ₁ ..... C ₂₄ ), and to each column (C _1). ..... C _24), perform the entire process is repeated until the end of the second byte and the third byte of the Enlarged character print method of the printer to the enlarged character one dog 72 is characterized by being a process for printing on a sheet of paper. ※ Note: The disclosure is based on the initial application.
