Final answer:
The incorrect statements are that printer speed is measured in words per minute and printer resolution is measured in pixels; the former is measured in pages or images per minute, and the latter in dots per inch.
Step-by-step explanation:
In addressing the provided statements, we need to identify which ones are incorrect. Let's evaluate each one:
- Printer output is often called hard copy, which is a correct statement.
- Printer speed is not typically measured in the number of words printed per minute. This statement is incorrect; printer speed is usually measured in pages per minute (ppm) or images per minute (ipm).
- The memory within a printer is indeed used to store printing instructions and documents waiting to be printed, making this a correct statement.
- Printer resolution is not measured in px or pixels. This statement is incorrect as printer resolution is typically measured in dots per inch (dpi). Pixels are used for digital displays, not for printer output.
Therefore, the incorrect statements are the ones claiming that printer speed is measured in words per minute and printer resolution is measured in pixels.
