hoffset
Hoffset is a TeX/LaTeX parameter that controls the horizontal offset of the text area on a page. It is a length register that shifts the origin of the text block relative to the page edges. By default, TeX places the left edge of the text block one inch from the physical left edge of the page; the hoffset value adds to that baseline. Positive values move the text block to the right, increasing the left margin; negative values move it to the left.
In practice, hoffset is rarely used directly in modern documents. In LaTeX, the effect of hoffset combines
Usage examples: in plain TeX, one might write \hoffset=12pt to shift the text block right by 12
