Which of the following is an invalid pair?

Correct option is D

132 column printers paired with inkjet printers is an invalid pair. Inkjet printers are typically used for high-quality color printing and not for specific column-based printing like dot matrix or line printers, which are more suited for tasks requiring a specific column format, such as printing large tables or continuous forms.
Important Key Points:
1. Inkjet printers are used for high-quality color printing, not for 132-column format printing.
2. Impact printers like dot matrix or line printers are typically used for printing in column formats.
3. Understanding the capabilities and uses of different types of printers is important for selecting the right printer for specific tasks.
4. Inkjet printers excel in photo and document printing, while dot matrix printers are used in industrial settings for printing receipts or multi-part forms.
Knowledge Booster:
· Impact Printers: Use mechanical impact to transfer ink from a ribbon to paper, suitable for forms requiring multiple copies.
· Inkjet Printers: Use liquid ink sprayed through microscopic nozzles, ideal for high-quality graphics and text.
