Apr 05, 2025 pm 04:33 PMProgramming control browser printing limitations of setting header footer default check status
During web page printing, developers often want to control the printing settings through code, such as unchecking the default header footer or customizing the header footer content. However, it is not feasible to directly manipulate the browser's print settings (including the default check status of the header and footer) through JavaScript or CSS.
This is mainly because the browser printing settings are controlled by the browser itself or the operating system and the printer driver, which exceeds the permission scope of the front-end code. Even if you use the @media print
CSS rule to customize header footer content, it is not possible to override the default settings of your browser or printer, especially when using plugins like printJS, which is more obvious.
For example, the following code snippet attempts to customize the header and footer using @media print
and printJS plugin, but the effect may not be ideal:
html2canvas(this.$refs.templateToImg, { backgroundColor: null, useCORS: true, windowHeight: document.body.scrollHeight, }).then(canvas => { dom.style.height = 'calc(100vh - 400px)' dom.style.overflow = 'auto' const url = canvas.toDataURL('image/jpg') this.img = url const styles = "@media print { @page { height: 100%; @top-left { content: 'top content'; } @bottom-center { content: 'footer content'; } } }"; printJS({ printable: url, type: 'image', documentTitle: this.previewTitle(), style: styles, onLoadingEnd: () => { this.printLoading = false dom.style.height = 'auto' dom.style.overflow = 'visible' } }) })
The reason is that printJS (and other similar print libraries) usually sends content directly to the printer, bypassing the browser's default print dialogs and settings. Therefore, the @media print
style rule cannot take effect.
In short, there is currently no reliable JavaScript or CSS method to directly control the header footer check status in the browser's print settings. Developers need to consider other alternatives based on actual needs, such as pre-include header and footer content in the printed content, or guide users to manually adjust settings in the browser print dialog box.
