PURPOSE:To make the increase of the developing speed of a pattern possible, by adding the information indicating whether the printing is possible or not when the information of a character is developed to the pattern of the character. CONSTITUTION:CPU7 once stores the data inputted from a data source 2 into an input buffer 3. Thereafter, when it is stored in a page buffer 4, in the case where there is some possibility that the character, signal, etc. developed by patterns are outside the output paper of a printer 10 on the basis of the positional information of a document information, the information indicating abovementioned matter is written in a memory 6. CPU7 successively reads the data of the page buffer 5 and carry out the pattern development on the basis of the pattern information of a font memory 11. This pattern memory is stored in a bit map memory 8. Besides, CPU7 checks the contents of the memory 6 and when the code of the character position indicated in the memory 6 is developed by patterns, whether it is outside the output paper is judged. Thereby, CPU7 is not required to check whether the result is outside the output area when the pattern development is carried out.
