Landscape Printing from HTML: Browser Support and Alternatives
When printing documents with numerous columns, it is often desirable to use landscape orientation to improve readability. However, this may require manual adjustments in the document settings. This article explores whether it's possible to print landscape directly from HTML, without user intervention.
CSS @page Property
The CSS @page property can be used to specify the page size and orientation for printing. To set landscape orientation, use the following code:
@media print{@page {size: landscape}}
Support:
- IE7: Appears to work, but it's likely remembering the user's previous selection.
- Other browsers: Not supported, as the @page size attribute is not part of any web standard.
Workarounds:
- Scripting: Using JavaScript or ActiveX to send keys to the user's browser to change printing settings. However, this is unreliable and may require altering security settings.
- Rotating Content: Rotating the content using CSS instead of the entire page. This can cause alignment and layout issues.
- Generating PDF: Creating a landscape version of the document in PDF format and configuring it to automatically print when selecting the print option. However, this may not work properly in IE7.
Conclusion:
Setting landscape orientation from HTML is challenging due to limited browser support. While the @page property may seem to work in some cases, it's not reliable. Other alternatives, such as scripting, rotating content, or generating PDFs, may be necessary depending on the browser and the document's content.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
