Printable Area & Orientation collects practical CAD plotting guidance for this topic within Paper Sizes & Margins. Use these articles for setup, verification, troubleshooting and reliable final output.
Landscape and portrait describe how the sheet is oriented; rotation controls how AutoCAD sends that sheet to the selected device. Start with the real paper size, match the Layout title block, then Preview.
Paper size is the full physical sheet; printable area is the smaller region the selected device can actually mark. AutoCAD shows the effective printable boundary in the Layout, and it changes with the printer/PC3 and paper size.
A cut-off border usually means the title block extends beyond the selected device’s printable area, the wrong paper size is selected, or downstream PDF/printer scaling is changing the sheet.
