How to Doodle a Printer
To doodle a printer, begin by doodling what looks like a square tongue sticking out of a mouth. This tongue will become the paper that your printer spits out.
Now draw a rectangle around the mouth of the printer. Notice how the rectangle is partially hidden behind the printer paper.
Add a third-dimension to your printer using straight lines. Notice the consistency of the angles of the lines. Also, take into account the length of the lines in comparison to the rectangle you drew in step 2.
To doodle the print paper feeder, use straight lines extending from the backend of the printer. Also, add some details to the front of your printer using an arc shape and three small ovals.
Add the finishing touches to your printer doodle by giving it some color. Notice the different shades of gray used within the example. This gives our printer a neat shadow-light effect.
