In the company to do system, to use A4 paper printing things, A4 paper standard mm, converted into pixels do not know. Search the Internet, find an article, turn around, spare.

A4 paper size is 210mm*297mm, that is 21.0cm*29.7cm, and 1 inch =2.54cm, if the screen dpi resolution of 72 pixels per inch, conversion: equivalent to 1cm can be rendered (72px/2.54cm) = 28.34px

Here are some of the pixel dimensions of A4 paper on the screen at some common resolutions:

When the resolution is 72 pixels per inch, the pixel of the A4 paper size image is 595x842;

When the resolution is 96 pixels per inch, the pixel of the A4 paper size image is 794x1123; (default)

When the resolution is 120 pixels per inch, the pixel of the A4 paper size image is 1487x2105;

When the resolution is 150 pixels per inch, the pixel of the A4 paper size image is 1240x1754;

When the resolution is 300 pixels per inch, the pixel of the A4 paper size image is 2480x3508;

A dpi (Dot Per Inch) indicator must be used when converting metric length units to screen resolution.
After my careful testing, found that the Web page printing, the default is 96dpi, not the rumored 72dpi

A4 paper size is 210x297mm, 1 inch =25.41mm conversion, that is 8.264x11.688 inch

So, the resolution of A4 paper 96dpi is 794x1123, which is the pixel we need when we make the Web page.

However, the printer is not full-width printing, there will always be a margin, so we must reduce the page margins when making the page.

Here are the pixel sizes for A4 paper that I tested under various margins:

The resolution of the largest element within the page when the print margin is set to 0mm: 794x1123

The resolution of the largest element within the page when the print margin is set to 5mm: 756x1086

The resolution of the largest element within the page when the print margin is set to 19.05mm: 649x978

Other sizes, general standard printing at 300dpi:

A4 the size of the image pixels of the paper is 2480x3508;

A3 the size of the image pixels of the paper is 4960x3508;

B3 the size of the image pixels of the paper is 3248x4300;

B4 the size of the paper, the pixel of the image is 3248x2150.
