A printer control apparatus includes a color-assigned font determining device for determining whether or not a color-assigned font is included in a print font pattern to be downloaded in a connected printer, and a notifying device for notifying a user that a color-assigned font is included in a font pattern downloaded in a printer. If the determination is affirmative, the user is notified of the fact, and can then input processing commands relating to the color-assigned font for output. It is thereby possible to distinguish a font to which a color is assigned from other fonts even when all the fonts are output by a unicolor printer.
