One point means one face parallel to you
One-point perspective applies when you are looking straight down something: a corridor, a street, a room from the doorway, a railway line. One face of everything faces you squarely and stays undistorted, while depth runs back to a single point. The moment you turn to look at a corner rather than a face, you need two points instead.
It is the easiest and the most easily overdone
Because it is simple to construct, one-point perspective gets used for scenes that would be better in two-point, and the result reads as flat and staged. It is genuinely right for symmetrical, head-on compositions and for interiors where you want the viewer to feel placed in the center of the room. Used elsewhere it looks like a diagram rather than a drawing.
Move the horizon deliberately
The horizon is eye level, and the vanishing point sits on it. Low on the page and the viewer is a child or lying down. High and they are looking down from a balcony. It is the single most consequential choice on the sheet and the one most people leave wherever the default put it. Decide it before you draw the first line.
Printing it accurately
This only measures correctly if your printer doesn't rescale the page. In the print dialog set Scale: 100%, not "Fit to page" or "Shrink oversized pages". If you're not sure it worked, print the calibration page, measure the ruler on it with a real ruler, and it will tell you exactly what your printer is doing to the page.
