In Excel 2011 for Mac, I was able to print to custom paper sizes. Excel 2016 for Mac (version 15.39) does not permit this. Windows live movie maker 2011 for mac. I am running Mac OS Sierra Version 10.12.6.

You need to install printer drivers. The PageSetup class of Excel must interact with the printer drivers I'm having similar issue running related code on Windows 8 operating under Mac Parallels (Virtual Machine). For anyone who are doing Visual Studio deployment on Mac Parallels, here's what I'm doing: • Disable Printers sharing between Mac and Windows. Go to Parallels (VM) > Configure > Hardware and click Print. Uncheck 'Add all Mac printers' and 'Synchronize Default Printer' • Install printer's driver on Windows • In order to get assigned IP address by the same wireless router (if you need to connect to printer wirelessly), you need to set up networking as bridged. Go to Parallels (VM) > Configure > Hardware >Adobe photoshop for mac serial number. 'Network 1' and choose Networking type as Airport and DHCP server as Auto. The issue at the core is in the _paperSize constant.

In my case, it was giving the same error on: (forgive c#) worksheet.PageSetup.PaperSize = Excel.XlPaperSize.xlPaperLedger; depending on the printer, for example the 'ledger' size paper may be defined as 11x17 or Tabloid. Find out what the print driver refers to the page sizing and then DIDN'T WORK: excel.ActiveSheet.PageSetup.PaperSize = Excel.XlPaperSize.xlPaperLedger excel.ActiveSheet.PageSetup.PaperSize = Excel.XlPaperSize.xlPaper11x17 WORKED: excel.ActiveSheet.PageSetup.PaperSize = Excel.XlPaperSize.xlPaperTabloid I hope this can help anyone having frustrating issues with funny inconsistencies of Microsoft Excel's enums.
