My black ink is very low, can I switch with my color cartridge and fool my printer?  I was gonna just do it, but then I realized that someone here can probably answer the question for me.  I have had to use staples before when my tape ran out unexpectedly!!!!!!  That should be mentioned in the pbs rules - Make sure you have enough materials on hand!!!  Thanks

I don't think so, because aren't the teo cartridges diffrent sizes?  It would hurt to try, but don't hold yourr breath.  I generally buy two B&W cartridges at a time......something to think about!?

You know, I have never had a cartridge run out before-------dry up perhaps, but this site has opened up all kinds of new experiences!  So, yup,  buying 2 black inks at a time is a good idea!

You buy two when you put the second one in or you buy one when you put the first one in. Depends on how effieient you want to be!!

if you have a color cartridge and a black cartridge in the same printer, it will switch to the color cartridge to print black ink. however, it usually looks kinda purple and uses up LOTS of ink. i would avoid that at all costs. it cheaper to replace the black one than the color one

I have done something similar.  The black ink ran out and my printer uses a composite of the color cartridge to make a grayish ink that is similar to black.  You might see if you have an option to print in grayscale or something like that in your print menu.  Mine does it automatically if my black ink is out, but you might have to change your settings or something. 

best of luck!

When you need more ink, try inkgrabber.com. I have to use 4 cartriges - one for each color - and they are normally 15-20 bucks in the store...on the site, they are 5 bucks each. Not all have a good deal, but it doesn't hurt. And shipping is pretty fast :)

Another possibility for no-ink is to display the page, then write the address by hand on the package.

[[Doesn't work for DC or printable postage, of course :).]]]

Thanks, I got the hint and bought 2 this time!
