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.
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.
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.
