Hello! Try checking if the printer you're printing to supports the JPEG datatype. This may be configured on the printer, but you might get more info by running "get-printer | format-list" in powershell.

Also, are you printing to Microsoft's "Print to PDF"? This throws the same error for me, even though it supports the datatype I'm sending to it.
