My steps (in pseudo-code) are:
1) open template XLSX file in aspose.cells
2) adjust values
3) save in-memory spreadsheet using aspose.cells
4) print saved file => desired output
5) print in-memory spreadsheet using aspose.cells => uses wrong font
My desire was to skip steps 3 and 4 and I don't see why, if the in-memory spreadsheet already has the correct fonts, that step 5 apparently altered the fonts back (in this case) to "Free 3 of 9 Extended". I do not want aspose.cells changing any formating implicitly.
