Plot AutoCAD drw to pdf

[Anonymous]

Why I cannot plot my drw?

That is asking you to select a different driver first in PLOT command, then save that setting (also on the PLOT command pop-up).
Repeat or every file and every layout.

That's how AutoCAD works when it cannot find the exact plotter saved inside the DWG file.

To plot to PDF select any if the drivers that are for that purpose . Not the Canon one. https://knowledge.autodesk.com/support/autocad/learn-explore/caas/CloudHelp/cloudhelp/2016/ENU/AutoC...
