Telescripter printer

Mobile teleprinters are looking increasingly attractive to vehicular communication system engineers, especially as automation enters the dispatching scene. A dot matrix page printer is described. The dot matrix approach enables the use of visual error correction since noise generally appears as miscellaneous extra or missing dots. The character remains recognizable. Although the operation of the printer mechanism was detailed, extensive field tests and optimum modulation selection had not yet been completed as of the symposium date. The dot matrix printer affords the capability of rough picture or map transmission as well as character information transmission.
