Abstract

The present invention relates to a font downloading apparatus and method which can download fonts of a coding scheme not supported by a printer after converting them into a supported coding scheme. When a user on a host computer selects a printer to which a font is to be downloaded, the system acquires coding schemes supported by the selected printer. Then, when a font to be downloaded is specified, the system acquires the coding scheme of the font. If the font to be downloaded is not supported by the printer, the system makes the user to select one of the acquired coding schemes, converts the codes of the font to be downloaded to the selected coding scheme, and downloads the font to the printer.

Claims

1. A font downloading apparatus for downloading fonts to a character output apparatus, comprising:

a selector for allowing one of character coding schemes supported by the character output apparatus to be selected if the character coding scheme of the fonts cannot be used on the character output apparatus;

a converter for converting the character coding scheme of the fonts into the character coding scheme selected via the selector; and

a downloader for downloading the fonts whose character coding scheme has been converted by the converter onto the character output apparatus.

2. The font downloading apparatus according to claim 1, further comprising:

an acquisition unit for acquiring coding schemes supported by the character output apparatus from the character output apparatus; and

a determination unit for determining that the character coding scheme of the fonts cannot be used by the character output apparatus if the coding schemes acquired by the acquisition unit do not contain the character coding scheme of the fonts.

3. The font downloading apparatus according to claim 1, further comprising:

a storage for storing the type of the character output apparatus and character coding schemes supported by the character output apparatus by associating them with each other; and

a determination unit for determining that the character coding scheme of the fonts cannot be used by the character output apparatus if the coding schemes associated with the character output apparatus do not contain the character coding scheme of the fonts.

10. The font downloading apparatus according to claim 1, wherein after being converted by the conversion means, character codes are further converted into printer character codes by the character output apparatus.

11. The font downloading apparatus according to claim 10, wherein, the character codes after conversion by the conversion means are Unicode character codes while the printer character codes are Western European, Cyrillic, or other character codes associated with a language or region.

4. A font downloading method for downloading fonts to a character output apparatus, comprising:

a selection step of allowing one of character coding schemes supported by the character output apparatus to be selected if the character coding scheme of the fonts cannot be used on the character output apparatus;

a conversion step of converting the character coding scheme of the fonts into the character coding scheme selected in the selection step; and

a step of downloading the fonts whose character coding scheme has been converted in the conversion step onto the character output apparatus.

5. The font downloading method according to claim 4, further comprising:

an acquisition step of acquiring coding schemes supported by the character output apparatus from the character output apparatus; and

a step of determining that the character coding scheme of the fonts cannot be used by the character output apparatus if the coding schemes acquired in the acquisition step do not contain the character coding scheme of the fonts.

6. The font downloading method according to claim 4, further comprising a step of reading character coding schemes supported by the character output apparatus and stored being associated with the type of the character output apparatus out of storage means and determining that the character coding scheme of the fonts cannot be used by the character output apparatus if the coding schemes associated with the character output apparatus do not contain the character coding scheme of the fonts.

7. A computer program product for downloading fonts to a character output apparatus, comprising:

code for a selection step of allowing one of character coding schemes supported by the character output apparatus to be selected if the character coding scheme of the fonts cannot be used on the character output apparatus;

code for a conversion step of converting the character coding scheme of the fonts into the character coding scheme selected in the selection step; and

code for a step of downloading the fonts whose character coding scheme has been converted in the conversion step onto the character output apparatus.

8. The computer program according to claim 7, further comprising:

code for an acquisition step of acquiring coding schemes supported by the character output apparatus from the character output apparatus; and

code for a step of determining that the character coding scheme of the fonts cannot be used by the character output apparatus if the coding schemes acquired in the acquisition step do not contain the character coding scheme of the fonts.

9. The computer program according to claim 7, further comprising:

code for a storage step of storing the type of the character output apparatus and character coding schemes supported by the character output apparatus by associating them with each other; and

code for a step of determining that the character coding scheme of the fonts cannot be used by the character output apparatus if the coding schemes associated with the character output apparatus do not contain the character coding scheme of the fonts.
