AutoCad :: How To Creates PDF With Paper Size

I have the next problem with PDF printer:

I have configured a special size and assigned to a PC3 file

(1350.00 x 1050.00 mm.)

This is the default printer for some other layouts in some other DWG's as well.

If I print the layout directly from the drawing editor, it creates a PDF with the paper size I assigned, but if I print it using the sheetset, it creates a document with another paper size based on I don't know what.

The plot and publish details window shows the next message when printed from the sheetset

Sheet: BA_00-P-050-0100___ - Plotted

Page setup:
Device name: DWG To PDF.pc3 - plotted to file
Plot file path: ...DesktoppublishBA_00-P-050-0100___.pdf
Paper size: ISO full bleed B0 (1414.00 x 1000.00 MM)

I cannot find the mistake.
