我正在使用geometry这样的包：
\usepackage[landscape]{geometry}
\newgeometry{twocolumn, left=0.25cm, right=0.25cm, top=0.8cm, bottom=0.4cm}
和fancyhdr这样的包装：
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhf{}
\fancyhead[L]{\bf{Some text}}
\fancyhead[C]{\leftmark}
\fancyhead[R]{\thepage}
\fancyheadoffset[L]{0.42cm}
\fancyheadoffset[R]{-0.26cm}
并且所有带边距的内容都正常。但是当我在纸上打印 PDF 时，所有边距都会发生变化。如何修复打印页边距？
所有代码如下所示：
\documentclass[8pt]{extarticle}
\usepackage[cp1251]{inputenc}
\usepackage[russian,english]{babel}
\usepackage[landscape]{geometry}
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhf{}
\fancyhead[L]{\bf{Some text}}
\fancyhead[C]{\leftmark}
\fancyhead[R]{\thepage}
\fancyheadoffset[L]{0.42cm}
\fancyheadoffset[R]{-0.26cm}
\setlength{\headsep}{0.2cm}
\usepackage{listings}
\usepackage{color}
\definecolor{mygreen}{rgb}{0,0.6,0}
\definecolor{mygray}{rgb}{0.5,0.5,0.5}
\definecolor{myviolet}{rgb}{0.5,0,0.36}

答案1
可能的原因：
Acrobat Reader/缩小至可打印区域
使用 Acrobat Reader 打印的选项有（命名可能有所不同）：
- 没有任何
- 适合页面区域
- 缩小至可打印范围
默认值为 (3)，即如果需要，页面会缩小以适合可打印区域。选项 (2) 也可以放大页面。您需要“无”以避免缩放。
纸张尺寸错误
某些 TeX 发行版可以配置默认纸张大小。但这不会改变标准类的默认设置。如果没有纸张大小选项，标准类将使用letterpaper。如果将边距设置为信纸大小，则 A4 纸上的边距不正确。
备注：LaTeX 和标准类不会告诉驱动程序正确的纸张大小。后者由诸如geometry、、
hyperrefsome pdftex.def（graphics/的驱动color程序）、… 等软件包完成。如果没有这样的软件包和纸张大小选项，结果可能是纸张大小为 A4（TeX 发行版/驱动程序默认）的 PDF 文档，但在 LaTeX 级别，页面布局（包括边距）配置为信纸大小。
更新：使用的类是extarticle，其默认是信论文，因此a4paper需要选项：
\documentclass[a4paper,8pt]{extarticle}
