Projector and projector system

An electronic typewriter for printing a document having a fixed format with portions thereof containing replaceable character code. The document is stored in an external storage device and read out until a replaceable character code is detected. The replaceable character code is acted upon by replacement with substitute character code or deletion thereof based on instructions communicated to a keyboard. Following input of the instructions, the document is once again read out from the external storage device until the next replaceable character code is detected and acted upon. The sequential reading of the document, detection of and acting upon the detected replaceable character code and automatic reading of the remaining portion of the document until detection of the next replaceable character code, continues until the entire document is read out of the external storage device. The entire document can be printed at one time following the input of all information or can be printed one line at a time following the input of information for that particular line.
