A customer reports that a text-only document prints with unrecognizable characters. The print preview correctly displays the document. Which of the following is the most likely cause of the issue?

Outdated firmware could cause various printer issues, but it's less directly implicated in garbled text when the print preview is accurate, compared to a driver issue.

An incorrect or corrupted printer driver can cause garbled text output because it translates the document data into instructions the printer understands; if this translation is flawed, the printer will produce unreadable characters even if the original document and its preview are fine.

A bad toner cartridge would typically result in blank pages, faded print, or streaks, not unrecognizable characters where text should be.

A corrupted document file would usually manifest in the print preview as well, showing errors or blank spaces, rather than appearing perfect in preview and garbled on print.
