My HP printer prints blank pages, what could be the cause?

Blank pages can be caused by several factors: empty ink/toner cartridges, a clogged print head, incorrect printer settings (e.g., printing in draft mode), or a driver issue. First, check ink/toner levels. Then, try running a print head cleaning. Verify the printer settings and ensure you haven’t accidentally selected a setting that would result in blank prints. Finally, update or reinstall the printer driver.
