Problem Description

What is the function of this PageSize? Is it set to directly change the paper selected by the printer? Is it just used to constrain DOM?

Proposed Solution

I hope there is a way to change the printer paper

Alternatives Considered

none

Additional Information

pageSize is an optional width and height in microns. When a custom pageSize is passed, Chromium attempts to validate platform specific minimum values for width_microns and height_microns. Width and height must both be minimum 353 microns but may be higher on some operating systems.

From looking at the code, it doesn't appear to me to affect the choice of paper feed. (However I don't physically have a dual-feed printer to test this with.)

@ckerr After I set PageSize, won't he change the paper in this place? Can I override the default paper size

correct from @ckerr here. Chromium does not give us the option to specify paper feed, and as such this isn't something we'll be able to implement more then we do with existing options.
