Thank you for using Syncfusion products.
You can use SfRichTextBoxAdv control to load Word documents. Using GetPageAsImageAsync() method, you can retrieve the page in SfRichTextBoxAdv as BitmapImage by specifying the page number. You can then print these bitmap images using PrintManager. We have prepared a sample to demonstrate the same. Please do find the sample from below link.
Please let us know if you have any other queries.

I just wanted to know if it was possible to do the same ( print word document ) but with an Excel document ?
I know that SfRichTextBoxAdv can't open Excel document but maybe an other control could and would allow me to print it ?
