Name all five printer types covered in CompTIA A+ Core 1, and give one real-world use case for each.
Laser = high-volume office text / Inkjet = color photos / Thermal = receipts and labels / Impact = carbon-copy multipart forms / 3D = prototypes and physical objects
Name the six steps of the laser printing process in order.
Charge → Expose → Develop → Transfer → Fuse → Clean
Name the four connection methods a printer or MFD can use to connect to a network or computer, and identify which is most reliable for a high-use office department.
