解説
問 94
- ア
正解 An inkjet printer turns liquid ink into fine particles (dots) and sprays them directly from the nozzles of the print head onto the paper, forming characters and images from the collection of these dots. Choice ア, “sprays fine ink particles directly onto the paper to print,” describes exactly this action, so it is the correct answer. It is quiet, good at color printing, and is widely used in home printers.
Incorrectイ
Striking an ink ribbon against the paper with wires (pins) to print describes a dot-impact printer. Because it prints by physically striking, it can handle carbon (multipart) paper, but this differs from the inkjet spraying method.
Incorrectウ
Heating heat-melting ink with the print head and transferring it onto the paper describes a thermal-transfer (meltable-type) printer. It is used for printing labels and the like (receipts mostly use the direct thermal method, which uses no ink and makes thermal paper change color), and its mechanism differs from the inkjet, which sprays liquid ink.
Incorrectエ
Using laser light to form an electrostatic latent image on a photoconductor (drum), then attaching powdered toner and transferring and fixing it onto the paper, describes a laser printer. This is an electrophotographic method that uses toner, a different method from the inkjet, which sprays liquid ink.
ここがポイント
- Inkjet printer = a method that sprays fine particles of liquid ink directly from the nozzles onto the paper.
- Telling the main printer methods apart: dot-impact (wires strike the ribbon) / thermal-transfer (heat melts the ink) / direct thermal (heat colors thermal paper) / laser (toner adheres to the photoconductor).
