Traditionally, printing is usually done with black ink on white paper, but there are ways to reverse this. How you do so depends on the software and hardware available to you. The hardware that is most relevant in this case is your printer, as some printers will already have white ink, and some will require a cartridge change to enable them to print in white.
Open your printer so that you can see the compartment with the ink cartridge.
Remove the black ink cartridge by following the instructions for your specific printer. Insert the white ink cartridge in place of the black one.
Remove the white paper from your printer tray and insert the black paper.
Type the text you want in standard black font. By doing this first, you will be able to check over your document and adapt the layout of the page.
Highlight your text by clicking your mouse next to the text and dragging the mouse so that all the text is highlighted.
Click the "Home" tab at the top-left side of the document. You should see an icon of the letter "A" with a small down arrow next to it.
Click on this down-arrow button. You will be presented with a palette of different-coloured squares. Select the white square. Now it will look as if your writing has disappeared.
Click the "Office" button at the very top-left corner of your screen. Select the "Print" button and choose your print options from the pop-up screen--the number of copies you want, pages per sheet and so on.
Click the "OK" button, and your document will print out.
Check the ink cartridge in your printer. If you have a colour printer, you may see that you already have white ink. If this is the case, then there is no need to change cartridges.
Be sure to refer to your printer's instruction manual to check the correct method for removing and inserting ink cartridges.
