What you’ll learn

  1. From Page Description to Marks on PaperOutline the print pipeline from page description through resolution and CMYK.Firmware rasterizes a digital page into a plan of marks; color and DPI set the fineness of that plan.
  2. Inkjet: Droplets on DemandExplain inkjet droplet ejection and paper/ink interactions.Thermal or piezo nozzles spray liquid ink; media and alignment decide whether dots stay sharp.
  3. Laser: Powder, Charge, and HeatDescribe electrophotographic toner printing and contrast other marking methods.Charge, light, powder, and heat fuse a durable page; other printers use ribbons, heat, or entirely different processes.

Questions this course answers

Order the usual steps from document to finished page.

Description becomes a raster plan, then a physical marking process, then paper handling completes the job.

How does a typical consumer inkjet place color on paper?

Inkjet marking is droplet-based liquid ink, driven thermally or piezoelectrically through nozzles.

Match each laser-printer part to its role.

Electrophotography writes charge patterns, develops them with toner, transfers to paper, and fuses permanently.
