Standardize PDF paper size using soffice

soffice --headless "-env:UserInstallation=file:///tmp/LibreOffice_Conversion_${USER}" --convert-to pdf:writer_pdf_Export --outdir \tmp \tmp\fileName.extension

I am using the following command to help move a variety of PDF styles and/or formats into a format that US government agencies will accept. The only current roadblock is the need for A4 paper sizes. I was thinking this might work “–printer PaperSize=8.5x11” or this “–printer PaperSize=A4”, but it does not seem to. I can see command parameters here: soffice - Linux Man Pages (1) but it does not seem to include “PaperSize”.

Is there a better, more official site for obtaining all the command parameters?

Is there a means of setting the PDF page size using soffice at all?

Is there a means of setting the PDF page size via another tool?

Is there a means of setting the PDF page size using Java?

Unless I’m wrong, export to PDF uses the page size defined in the document. Consequently, to change stationery format, you need to change the page size in all page styles. I don’t think this can be done from command line.

@ajlittoz: you are absolutely right.
