A printer unexpectedly runs out of consumables in the middle of a print job. The printer requires polylactic acid (PLA) consumables. Which of the following printers is being used?
The correct answer is B. 3-D printer. A printer that uses polylactic acid (PLA) as a consumable is a 3-D printer, as PLA is a common thermoplastic filament used in fused deposition modeling (FDM) additive manufacturing.

Why each option
A printer that uses polylactic acid (PLA) as a consumable is a 3-D printer, as PLA is a common thermoplastic filament used in fused deposition modeling (FDM) additive manufacturing.
Impact printers use ribbons and pins to strike paper, and do not use PLA.
Polylactic acid (PLA) is a biodegradable thermoplastic commonly used as filament for 3-D printers that employ Fused Deposition Modeling (FDM) technology. These printers build objects layer by layer using such materials.
Laser printers use toner powder and a drum to print images, not PLA.
Inkjet printers use liquid ink cartridges to spray ink onto paper, and do not use PLA.
