I have no clue about whether the AOL update has anything to do with your printer problem. It seems unlikely, but I'm not an AOL user, thank goodness.
Did this problem start right after the AOL update? Does the printer behave the same way, regardless of what application (word processor, spreadsheet, etc.) you try to print from?
I have two BJC-2000 printers. I bought one and the other used to belong to my mother. Only one works now; however, I can remove the print head unit with the ink cartridges in it and put it in the other printer and then the printer works. This a clear indication that, indeed, the printer head unit in these printers can become faulty and need to be replaced. In the case of the printer that used to belong to my mother, I suspect months of non-use contributed to the demise of the printer head unit in it; long periods of inactivity are not good for printers.
The BC-21e package contains the printer head unit and the two ink tanks. From what I've seen, it retails for about $50. However, you might want to check for them on ebay. I just bought a new BC-21e on ebay for $25 (free shipping).
