No, I don't believe these functions are documented. I believe the dll was made in a fashion to match the generated code that AcuBench makes when you use the Report feature. Use AcuBench and Open the Reports.pjt and generate Report1a, you'll see calls like these:

CALL "AcuBenchPrintGetMargins"

CALL "AcuBenchPrintGetPaperSize"

CALL "AcuBenchPrintGetMargins"

CALL "AcuBenchPrintGetPaperName"

@shjerpe - Thank you.  That kind of stinks.    I just wanted to print without a preview but needed the correct arguments.  I did find what I needed using a similar method as what you described.  For future generations, this is what I used to avoid showing a print preview and print one copy:

              MOVE 1 to ACU-PAPER-COPIES

              CALL "@[DISPLAY]:AcuBenchPrintExecWBPrint" USING

                   BY CONTENT PRT-FULLFILENAME,

                   OMITTED,

                   BY CONTENT PRINT-BROWSER-PARA,

                   BY CONTENT ACU-PAPER-HEADER,

                   BY CONTENT ACU-PAPER-FOOTER,

                   BY CONTENT ACU-PAPER-SIZE,

                   BY VALUE ACU-PAPER-ORIENTATIONINT,

                   BY VALUE ACU-PAPER-COPIES,

                   BY CONTENT ACU-PRINTER-NAME

              END-CALL

All of the graphical examples examples that we provide has two pieces of code in the event editor

Report1c-After-Init.

          PERFORM Acu-Report1c-Preview      

Acu-Report1c-PREVIEW.

          PERFORM Acu-Report1c-PRINT-TOFILE

          PERFORM Acu-Report1c-PRINT-PARA

and calls CALL "AcuBenchPrintExecWBPreview" USING

You don't need to have these particular calls. You can just use

Acu-Report1c-PREVIEW.

          PERFORM Acu-Report1c-PRINT-TOFILE

          PERFORM Acu-Report1c-PRINT-PARA
