Html prop is a HTML string that will be converted to the PDF and then printer. Be sure to use PDF safe CSS. PageHeight and PageWidth props are needed so that the PDF converter knows the dimensions of the page. PaperSize property is used for the CUPS package to set the MEDIA property. Success and Error props are callbacks used for additional JS work needed to be done after printing operation finishes. Success callback returns JobID integer, and error callback returns string message with some information about the error.
