My poor printer must be breathing a huge sigh of relief - finished after a little over 8 hours of non-stop printing! What a wonderful workhorse it is!
Just made it too - about 200 sheets of paper left and both my red and black cartridges gave me the 'just about out of ink' warning! Although I still have one black cartridge left, that was my last red cartridge.
Still have to collate and bind it but this is such a relief to get this far.
Just FYI, the printer is an HP Officejet Pro 8600 purchased in July 2012. This is the fifth time I've printed "The Book" using it.
