 of actual performance, the data in the following table are representa¬tive of printing speeds.

The above estimates do not include the time on a general purpose computer which would be required for the preparation of input to the cathode ray printers.

RESOLUTION

Model

In order to gain some insight into possible factors in the resolution of a cathode ray printer, an analysis will be made on a specific model in which the raster on the cathode ray screen covers an area 10 cm × 10 cm square and contains 1024 × 1024 raster units. It will be assumed that hard copy from the cathode ray printer covers an area 6″ × 6″ and is viewed by a reader's eye at the conventional distance of 10″. 6
