PURPOSE:To attain efficiently editing work of a sentence, by calculating the number of print lines left on the location of edition at present with respect to a designated print paper size at all times and displaying the value on a display device. CONSTITUTION:The length corresponding to a paper size is expressed in the unit of mm. and this is stored in a fixed storage area 22. Further, the usable effective length with respect to this paper size, i.e., the length excluding the dead margin loaded to a printer, is stored in an effective length memory 20. Then, An operator stores paper feed pitch information possible for designation to a pitch memory 11. That is, the remaining line number data is calculated by a subtractor 14 and a divider 16 to renew the content. That is, the total used length is subtracted from the content of the memory 20 by a register SIGMALP13, and the remaining paper length is stored in a register 15. Then, the remaining paper length is divided by a line pitch 11 to obtain the remaining number of lines, which is stored in a memory 17. This is transferred to a display buffer 18 and displayed on a display device 19. |
