Publisher ExportAsFixedFormat ignores “Publication Page” while manual PDF/XPS export works
I am migrating a large archive of Microsoft Publisher files to PDF before Publisher is retired. We have isolated a repeatable problem in older publications. Example publication: Publisher page size: 210 x 148 mm, landscape • Manual export through File → Export → Create PDF/XPS → Options → Print Options • Settings shown by Publisher: • One page per sheet • Paper size: Publication Page • 210 x 148 mm • Landscape • Resulting PDF: 210 x 148 mm — correct However, both PowerShell/COM and VBA using Document.ExportAsFixedFormat produce a 215.9 x 279.4 mm portrait PDF. Explicitly using: PrintStyle:=pbPrintStyleOnePagePerSheet does not fix the problem. We tested the same publication using: Application.CommandBars.ExecuteMso "FileSaveAsPdfOrXps" This opens Publisher’s own PDF/XPS dialog. The dialog still shows Publication Page, 210 x 148 mm, landscape, and when published through that UI the resulting PDF is correct. We analysed 349 Publisher files: •120 exported with the correct page size • 229 exported with the wrong page size • all 229 failing files opened with an Adobe PDF / A4 portrait printer context The Publisher PageSetup.PageWidth and PageHeight values themselves remain correct. Question: Is there any documented or undocumented Publisher VBA/COM property, parameter, registry setting, or command that corresponds specifically to the PDF/XPS Print Options setting “Paper size: Publication Page”? In other words, how can ExportAsFixedFormat be made to reproduce exactly the same page-size behaviour as Publisher’s interactive PDF/XPS dialog? If this is not exposed through the Publisher object model, is automating the built-in FileSaveAsPdfOrXps command the only reliable approach? Publisher: Microsoft 365 desktop version on Windows.
