Image forming apparatus, image forming method, and non-transitory computer readable recording medium

An image forming method for an image forming apparatus including

• a memory configured to store font data of each of one or more fonts, and a list including the one or more fonts,
• a communication interface configured to receive printable data from a host device, the printable data including font specifying information and a character code, and
• a controller circuit configured to execute an information processing program to operate as a rendering module,
• the image forming method comprising:
• by the rendering module of the image forming apparatus,
• determining whether or not a specified font is included in the list, the specified font being a font specified by the font specifying information;
• if determining that the specified font is not included in the list,
• selecting any one alternative font from the list, the alternative font being one of the one or more fonts;
• determining alternative font rendering information to be rendered,
• rendering a character specified by the character code included in the printable data by using alternative font data by using the determined alternative font rendering information, the alternative font data being font data of the alternative font;
• and
• rendering alternative font rendering information, the alternative font rendering information being information indicating that rendering is executed by using the alternative font data, the alternative font rendering information being alternative font identifier information in association with position information if the alternative font identifier information is to be rendered in association with the position information, the alternative font identifier information being information identifying the alternative font, the position information being information indicating a position of the character rendered by using the alternative font data.

A non-transitory computer readable recording medium that records an information processing program executable by an image forming apparatus including

• a memory configured to store font data of each of one or more fonts, and a list including the one or more fonts,
• a communication interface configured to receive printable data from a host device, the printable data including font specifying information and a character code, and
• a controller circuit configured to execute an information processing program to operate as a rendering module,
• the information processing program causing the controller circuit of the image forming apparatus to operate as a rendering module,
• the rendering module being configured to
• determine whether or not a specified font is included in the list, the specified font being a font specified by the font specifying information,
• if determining that the specified font is not included in the list,
• select any one alternative font from the list, the alternative font being one of the one or more fonts,
• determine alternative font rendering information to be rendered,
• render a character specified by the character code included in the printable data by using alternative font data by using the determined alternative font rendering information, the alternative font data being font data of the alternative font, and
• render, as alternative font rendering information, the alternative font rendering information being information indicating that rendering is executed by using the alternative font data, the alternative font rendering information being alternative font identifier information in association with position information if the alternative font identifier information is to be rendered in association with the position information, the alternative font identifier information being information identifying the alternative font, the position information being information indicating a position of the character rendered by using the alternative font data.
