Abstract
A label printing apparatus for printing characters on a label. The apparatus includes a controller operable to perform various functions, such as (1) recalling stored common font data for each character selected and being operable to apply a scaling factor to the font data to produce print pixel data for printing the character; (2) deriving characters from the font data to determine sequentially intersections of lines and/or curves of the character with a print line extending heightwise to generate therefrom a set of pixel data for directly printing a column of dots corresponding to the set of pixel data defined at that print line; and/or (3) implementing a preview function which enables all characters of an entire label to be displayed at one time on a display even when the length of the label is greater than the size of the display. The preview function is implemented by the controller reducing the size of the characters to be displayed to such an extent that all of the characters of the label can be displayed simultaneously. Also, the characters that are printed resemble the characters which are displayed.
