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
