| 20100277755 | INFORMATION PROCESSING APPARATUS CONNECTED TO A PRINTING APPARATUS VIA A NETWORK AND COMPUTER-READABLE STORAGE MEDIUM HAVING STORED THEREON A PROGRAM FOR CAUSING A COMPUTER TO EXECUTE GENERATING PRINT DATA IN THE INFORMATION PROCESSING APPARATUS CONNECTED TO THE PRINTING APPARATUS VIA THE NETWORK - An information processing apparatus connected to a printing apparatus via a network encrypts print data if identification information is input, and does not encrypt print data if identification information is not input. If identification information is input and the print data has been encrypted, the information processing apparatus sends a print job including the encrypted print data to the printing apparatus via the network; otherwise, the information processing apparatus sends unencrypted print data to the printing apparatus via the network. | 11-04-2010 |
| 20110069338 | PRINT SYSTEM, CONTROL METHOD THEREFOR, INFORMATION PROCESSING APPARATUS, CONTROL METHOD THEREFOR, PROGRAM FOR IMPLEMENTING THE CONTROL METHOD, AND STORAGE MEDIUM STORING THE CONTROL PROGRAM - A print system which are capable of inhibiting simultaneous use of the encrypted print and the box storage to thereby increase the security of print data. A host computer has an encryption function of encrypting print data, and issues a print job for the print data encrypted by the encryption function. A print server receives the issued print job, and has a decryption function of decrypting the encrypted print data of the received print job. A printer has a storage function of storing the print data decrypted by the decryption function, and outputs the stored print data. At least one of the host computer and the print server inhibits simultaneous use of the encryption function and the storage function. | 03-24-2011 |

| 20090284777 | IMAGE PROCESSING APPARATUS, METHOD, AND COMPUTER-READABLE MEDIUM STORING THE PROGRAM THEREOF - An image processing apparatus receives page description data, converts the page description data, thereby generating first intermediate data that is described for each object, converts the first intermediate data, thereby generating second intermediate data that is described with edge information of an object, stores, in a storage area, data representing drawing position information of an object, determines whether the object overlaps with and is located behind another object, in the case where it is determined that the object is located behind another object, performs character recognition processing on the first intermediate data, whereas in the case where it is determined that the object is not located behind another object, performs character recognition processing on the second intermediate data. | 11-19-2009 |
| 20090284787 | OUTPUT EFFICIENCY OF PRINTER FORMING IMAGE BY INTERPRETING PDL AND PERFORMING OUTPUT BY USING PRINT ENGINE - A printer according to the present invention receives a PDL via a network. Thereafter, the printer creates metadata by interpreting the received PDL and extracting rendering attribute information used in each page. The printer generates vector data from the PDL. Based on setting information on the printer, the printer generates a display list from the vector data. The generated vector data, display list and metadata are stored in a storage device in the printer in association with each other. Thus, output efficiency is improved. | 11-19-2009 |
| 20100020338 | PRINTING APPARATUS, CONTROL METHOD, AND STORAGE MEDIUM - A printing apparatus determines the resolution of bitmap copy-forgery-inhibited pattern image data included in transmitted print data, and decides whether to print the bitmap copy-forgery-inhibited pattern image data onto a sheet based on the determination result. | 01-28-2010 |
| 20100265543 | IMAGE FORMING APPARATUS, METHOD OF CONTROLLING THE SAME AND PROGRAM OF THE SAME - An image forming apparatus comprises a reception unit configured to receive the print job from the external apparatus, a unit configured to spool the received print job, a development unit configured to develop the spooled print job to a printable data, a unit configured to detect network disruption in the network, and a control unit configured to, in a case of detecting the network disruption in the middle of spooling and developing the received print job, stop the development of the print job for a stop state and set a subsequent print job which is not in the stop state as an object of the development. | 10-21-2010 |
