IPP-FAX Processing Unit PDL to Image Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming apparatuses face challenges in performing fax transmission using the Internet Printing Protocol (IPP) FaxOut Service, as they need to convert Page Description Language (PDL) data into image data for transmission, which is not inherently binary and requires additional processing.
Innovation Solution
An image forming apparatus is equipped with an IPP-FAX processing unit that receives service requests, generates image data from PDL data based on provided image processing information, and stores it for subsequent fax transmission to a designated destination, utilizing separate processing units for data conversion and transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the image forming apparatus uses IPP FaxOut Service to receive PDL data for fax transmission, then the apparatus can accept fax data in various PDL formats from external devices, but the apparatus must perform additional conversion processing to transform PDL data into image data for fax transmission
Solution Approach 1:
The image forming apparatus is designed to handle multiple data types (PDL data and image data) through a unified processing architecture. The control unit can identify the data type of incoming fax data and automatically select the appropriate processing path, making the apparatus universally compatible with both PDL formats and image formats without requiring separate dedicated systems
Solution Approach 2:
The apparatus performs preliminary conversion of PDL data into image data and stores it in a box before fax transmission. This preliminary action allows the conversion processing to be completed in advance, separating the conversion step from the transmission step, and enabling efficient fax transmission of the converted image data
2Reliability
If the image forming apparatus performs conversion processing to transform PDL data into image data, then fax transmission can be achieved with the IPP FaxOut Service, but the processing time and complexity increase compared to direct image data transmission
Solution Approach 1:
The apparatus converts PDL data into image data and stores it in a box in advance before fax transmission is needed. This preliminary conversion action eliminates the need for time-consuming conversion during the actual fax transmission process, reducing the loss of time when fax transmission is required
Solution Approach 2:
The fax processing function is divided into separate modules: a PDL data processing unit that handles conversion, a box storage unit that holds converted image data, and a fax transmission unit that sends data. This segmentation allows each unit to operate independently and efficiently, reducing overall processing time

AI summary
An image forming apparatus includes an Internet Printing Protocol FaxOut Service (IPP-FAX) processing unit and first and second processing units. The IPP-FAX processing unit receives a service request relating to IPP-FAX from an external apparatus. The first processing unit generates, and stores, image data from page description language (PDL) data. The IPP-FAX processing unit acquires PDL data, image processing information, and destination information from the service request and notifies the first processing unit of the PDL data and the image processing information. The first processing unit generates, and stores, image data from the PDL data based on the image processing information. The IPP-FAX processing unit notifies the second processing unit of the destination information, and image data indicating information. The second processing unit performs fax transmission of the stored image data to a destination indicated by the destination information.
