Whether your printer is out of black ink or the assignment requires blue ink, you can print your documenst in blue ink. Word processing programs such as Microsoft Word let you change printer settings to blue ink. To print a document that you cannot edit first, such as a web page or .pdf document from an e-mail, the process is longer.

Click "File" and select "Print" from the drop-down menu. Click "Print" when the Print Options box opens.
Printing Documents You Cannot Edit
Purchase ink in your desired shade of blue.
Open your printer and replace its black ink cartridge with your new blue ink cartridge. Remove the colored ink cartridge if the printer has one.
Open the document. Click "File" and select "Print" from the drop-down menu. Click "Print" in the pop- up Print Options box. Although your document was created in black (or some other color) your printer will use the blue ink to print it.
