Printer (React)

The printer can also be seen as an export option, especially since most modern browsers allow users to redirect the output to PDF files, cloud storage, etc. The PrintDocument class makes it easy to create documents for printing. This sample shows how you can convert a FlexGrid into a table element suitable for printing with the PrintDocument class.
