A4 printers are the usual models that are on the desk or in the cupboard in almost every office and in many people's homes. If you only print school papers, business documents, or the occasional ticket, an A4 printer is the right choice. There are many versions. For example, black and white printers for text documents, color printers for images and presentations, simple printers for printing only, and all-in-one printers. There's enough choice.
