PURPOSE:To enable to make a hard copy in a short time, by a method wherein a pattern information the same as that on a CRT or the like is stored in a memory different from that for displaying, and printing is conducted by using the information when making a hard copy, in a hard copying device for a displayed pattern on a CRT or the like. CONSTITUTION:Various data are fetched from a central computer 1 by operating an operating part 6, are received by a receiving part provided in a controlling part 4 of a terminal device 3, and are fed to the CRT5 and a memory part 7. The CRT5 momentarily stores the received data in a buffer memory 9, and displayes them on a display device 10. The data modified on the basis of the display are inputted through the operating part 6, and the corrected data are inputted into the memory part 7, and are displayed on the display device 10. When a hard copy is required, the operating part 6 is so operated that the controlling part 4 drives a printing part 8 to read the data from the memory part 7 and make a hard copy 11. Accordingly, since the printing part 8 can make a hard copy irrespectively of the scanning of the CRT, synchronism-waiting period can be unnecessitated, and hard copy making period can be shortened. |
