PRINT OUTPUT UNIT, PRINT OUTPUT SYSTEM, PRINT OUTPUT METHOD AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a print output unit, a print output system, a print output method and a recording medium in which a color screen can be printed clearly by means of a monochromatic printer. SOLUTION: At least the color of symbols, e.g characters or codes, in a screen image presented on a display means 13 is altered to black by a black color altering means (e.g. a CPU 10) and a print command of the screen image including the symbols converted to black color is delivered to a printer 2 by an output means (e.g. the CPU 10). Consequently, the symbols printed by the printer 2 entirely have black color of uniform gray level. A color screen image can thereby be printed clearly by a monochromatic printer 2.
