PURPOSE:To select an optional display screen and record its data by transferring one-screen data from the 1st memory to the 2nd memory in response to a recording command, and recording the stored data on a printer. CONSTITUTION:Buffer memory 7 for hard copying is provided independently of buffer memory 4 for display. Data displayed on a CRT3 is sent out of a computer through a bus 1 and stored in the memory 4. The data forms a display screen through a controller 2 and characters, numbers, etc., are displayed on the screen of the CRT3. When an operator who monitors the display screen sends out a recording command, one-screen data in the memory 4 is transferred to and stored in the memory 7. One-character data read out of the memory 7 is transferred to a controller 5, which is actuated to record the data on a printer form through a printer 6. |
