Automatic scaling for legibility

A computer program product comprising:

• one or more computer-readable storage media and program instructions stored on the one or more computer-readable storage media, the program instructions comprising:
• program instructions to receive a file to print to a target printing device;
• program instructions to generate a print preview of the file based, at least in part, on one or more configurations of the target printing device, wherein the print preview is generated at an initial scale;
• program instructions to generate a preview text for the print preview;
• program instructions to determine a plurality of legibility metrics based on a comparison between the preview text for the print preview and text of the file to print, wherein the plurality of legibility metrics correspond to a plurality of zones of the filo print preview;
• and
• in response to a legibility metric of the plurality of legibility metrics for a zone of the zones of the print preview being below a predetermined value, program instructions to print the zone of the file at a second scale, wherein the second scale is larger than the initial scale.

A computer system comprising:

• one or more computer processors;
• one or more computer readable storage media;
• and
• program instructions stored on the computer readable storage media for execution by at least one of the one or more processors, the program instructions comprising:
• program instructions to receive a file to print to a target printing device;
• program instructions to generate a print preview of the file based, at least in part, on one or more configurations of the target printing device, wherein the print preview is generated at an initial scale;
• program instructions to generate a preview text for the print preview;
• program instructions to determine a plurality of legibility metrics based on a comparison between the preview text for the print preview and text of the file to print, wherein the plurality of legibility metrics correspond to a plurality of zones of the print preview;
• and
• in response to a legibility metric of the plurality of legibility metrics for a zone of the zones of the print preview being below a predetermined value, program instructions to print the zone of the file at a second scale, wherein the second scale is larger than the initial scale.
