Laptops and Laser Printers

I was learning about laptops and laser printers. I knew everything about laptops. The laser printer stuff did not hold my interest. A lot of this stuff I hope to never need to use. I am not particularly interested in computer hardware repair. I feel like the first part of the A+ is all about knowing the parts of a computer. I respect that, but I cannot wait until I get into the more fun stuff like operating systems and all that. For now, I am just paying my dues and building my foundation.
