Appeal No. 1997-1381 Application 08/188,925 The invention relates to an image printer. The printer receives image data from a host computer. When a problem is detected, such as a paper jam, the image data is compressed and stored in a compressed format. Thus, when the image printing function is suspended because of the detected problem, the printer can continue to receive image data, thus enabling the host computer to continue with other operations. Because the image data received after the detection of a problem is compressed, the image data can be stored in a relatively small capacity memory. Representative independent claim 1 is reproduced as follows: 1. a printer apparatus arranged to actuate an image forming means based on a received print data for printing an image based on the print data, said printer apparatus comprising: a detecting means for detecting trouble in the image forming means, a compressing means for initiating the compression of the received print data upon detection of the trouble, a memory means for memorizing the compressed data, an expanding means for expanding data read from said memory means, and a control for instructing starting of said expanding 2Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 NextLast modified: November 3, 2007
