IMAGE FORMING APPARATUS THAT CONTINUES WITHOUT HALT TO PERFORM PRINT JOB INCLUDING SIGN WHERE GLYPH IS INVALID DATA, AND RECORDING MEDIUM

摘要

An image forming apparatus includes a print device, a sign printing circuit, and a sign analyzing circuit. The print device performs a print job onto a print medium. The sign printing circuit causes the print device to print a sign where a glyph is present in a font corresponding to a code based on the code included in print data. The sign analyzing circuit analyzes whether or not the glyph is invalid data where the sign printing circuit is not able to cause the print device to print. When the sign analyzing circuit analyzes that the glyph present in the font corresponding to the code of a target sign is the invalid data, the sign printing circuit causes the print device to print a specific alternative sign as an alternative to the target sign.
