## Abstract

A method, computer program product and computer system to improve print legibility is provided. A processor receives a file to print. A processor generates a print preview of the file, wherein the print preview is generated at an initial scale. A processor generates a preview text for the print preview. A processor determines a legibility metric based for the print preview on a comparison between the preview text for the print preview and text of the file to print. A processor prints the file at a second scale in response to the legibility metric being below a predetermined value, wherein the second scale is larger than the initial scale.

## Claims

### Claim 1

A method comprising:
receiving, by one or more processors, a file to print to a target printing device;
generating, by the one or more processors, 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;
generating, by the one or more processors, a preview text for the print preview;
determining, by the one or more processors, 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, printing the zone of the file at a second scale, wherein the second scale is larger than the initial scale.

### Claim 2 (depends on 1)

The method of claim 1, wherein the legibility metric is based, at least in part, on an edit distance between the preview text and the file text.

### Claim 3 (depends on 1)

The method of claim 1, wherein the legibility metric is based, at least in part, on recalled n-grams between the preview text and the file text.

### Claim 4 (depends on 1)

The method of claim 1, wherein the print preview is based, at least in part, on one or more of the following target printing device configurations: (i) print size; (ii) print area; and (iii) print resolution.

### Claim 5 (depends on 1)

The method of claim 1, wherein the method further comprises:
generating, by the one or more processors, a second print preview of the file, wherein the print preview is generated at the second scale;
generating, by the one or more processors, a second preview text for the second print preview;
determining, by the one or more processors, a second legibility metric based for the second print preview on a comparison between the second preview text and the text of the file to print; and
in response to the second legibility metric being below a predetermined value, printing the file at a third scale, wherein the third scale is larger than the second scale.

### Claim 6
