AutoCAD

The paper list depends on the selected output device. Choose the device first, then the exact paper, and remember that printable area can be smaller than the nominal sheet.

A good production sheet should print the same way tomorrow. Use a Layout, named Page Setup, locked viewport and controlled plot style instead of relying on memory.

Model Space printing is useful for quick details and one-off areas. Because there is no prepared paper sheet, you must choose the plot area and plot scale deliberately.

AutoCAD can show system printers and PC3 configurations in the same Printer/Plotter list. Pick the real target before paper because the device controls the available paper list.

Multiple copies are a device/output quantity setting after the sheet itself is correct. Validate one copy first so you do not multiply a bad plot.

A Layout is the easiest beginner workflow for a repeatable sheet: the paper stays at 1:1 while a viewport shows the full-size model at the required drawing scale.

A Page Setup is a saved group of output settings. It keeps you from rebuilding the same printer, paper, area, scale, plot style and orientation every time.

Plot Stamp can add drawing name, Layout, date/time, device, paper size and scale to output or a log. Use it only when your document-control workflow needs it.

Think of a Layout as the real paper sheet inside the DWG. Set the paper first, then place the title block and viewport on that sheet.
