What was the first color laser printer?
1995. Apple releases their first ever colour laser printer: the Color Laser Printer 12/600PS. The unit used a Canon-based engine and cost users upwards of $7,000 (with inflation today – $11,000 or £7,100).

What are the steps in a laser printer?
The seven steps of laser printing are: The computer sends the data to the printer. The PRIMARY CORONA WIRE negatively charges the PHOTOCONDUCTIVE drum to 600 to 1000 volts DC. The LASER SCANS or PAINTS the image to the drum. Anywhere the laser touches the drum causes the electrical charge to DRAIN OFF.
Which is better inkjet or laser?
PROS: Great for photos and image-heavy documents. Inkjet printers do a better job of blending smooth colors than laser printers. Inkjet printers have a low start-up cost. Printers are less expensive than laser printers and inkjet ink cartridges are cheaper than toner cartridges.
What is laser printing?
Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a “drum” to define a differentially charged image.
