接受来自计算机的文本和图形作为输入，然后以纸上打印信息的形式输出的设备称为打印机。它的大小、速度、复杂程度和成本各不相同。谈到打印机，您只有两种选择，无论您是购买喷墨打印机还是激光打印机。两种打印机都很好，可以根据用户的要求正常工作。
1. 喷墨打印机：
这些是将微小的墨滴喷射到纸上的机器。这些打印机墨盒中的墨水是液体形式。它们有喷嘴，将墨水喷到纸上并打印出来。这类打印机的缺点是，如果长时间不使用，墨盒中的墨水会变干。然后你必须清洁它才能再次使用它。
例子 –
HP Deskjet 1112 打印机、Epson L130 单函数打印机、Epson L361 打印机。
2. 激光打印机：
它是一种个人电脑打印机，使用非冲击即按键不会撞击纸张技术。其中使用的激光使用电荷在硒涂层鼓上绘制文档。与喷墨打印机相比，它们更可靠。他们不使用喷嘴，它的墨水是粉末状的，要放在给定的酒吧里，这就是为什么这些类型的打印机的墨水无论你每年使用一次还是不使用都不会干涸的原因。根本不用它。
例子 –
HP LaserJet 打印机
喷墨打印机和激光打印机的区别：
