Abstract: PURPOSE: To provide a method and a device for displaying an image and facsimile data in the display device of a host application. CONSTITUTION: A host computer 12 generates control/down load commands for displaying image or facsimile data. Image and facsimile data are processed by a non-programmable terminal(NPT) 14 or a programmable work station(PWS) 15 and are displayed on a display screen. When a user requests a different function, NPT 14 or PWS 15 stores image information and transmits image information to the host computer 12. Stored image information contains cache image counter data and scaling and observation image screen position data, which are used for restoring displayed image and facsimile data, when the user returns to the previous function.
