What is one likely cause of garbled printouts?

Garbled printouts typically occur when there is a communication issue between the computer and the printer, which can be significantly influenced by the printer driver. A corrupted printer driver can lead to incorrect data being sent to the printer, which results in jumbled or unintelligible characters on the printed page. This is because the driver is responsible for translating the data from the computer into a language that the printer understands, and if this translation process is disrupted due to corruption, the output will be problematic.

The other options may lead to different printing issues. For instance, low toner levels can cause faded prints or missing sections, while dirty feed rollers might result in feeding problems or paper jams, and a faulty ink cartridge could cause issues like streaking or inconsistent coloring. However, these conditions generally would not produce garbled text, which is more directly tied to a failure in the communication process managed by the printer driver.
