I don’t know about you but I hate reading off the screen, and print everything I want to read. When my printer is out of action it is a nightmare!! I have two HP printers and on these I can go into properties and change the quality to fast /draft, this is still a good quality of print, very readable but not so black and because of this it uses much less ink and your ink cartridge last longer. I can also change the print settings to have it permanently printing fast /draft. Not all printers offer this facility but it’s worth trying yours and see what you think. Where do you buy your ink? Supermarkets and Argos now sell ink cartridges,which may be cheaper than the stationers you are using. Some also sell their own brands. Or you may like to try compatibles, there is a variety in quality to these, some are guaranteed.
