Its a HP Deskjet 6980. The only different thing is I changed the colour
cartridge yesterday
Definitely run the alignment setting procedure.
However p 118 of the manual says that alignement is automatic after a
cartridge change:

Align the print cartridges
The printer automatically aligns the print cartridges after a new print
cartridge is installed.
You can also align the print cartridges at other times to ensure optimal
print quality.
To align print cartridges:
1. Load Letter or A4 plain, white paper in the In tray.
2. Open the printer Toolbox.
3. Click Align the Print Cartridges.
4. Click Align, and then follow the onscreen instructions.
But elsewhere I did find the warning that things can go wrong if you have
the printer powered OFF when you change a cartridge. It says the printer
will not release the cartridge but if you do get it out then ....
If you don't know how find out how to make the two kinds of test print:
-- one involves the PC and is usually a Test Print button in the
properties of the Printer icon in the Printer folder
-- while the other is independent of the PC and involves a combination of
buttons or turning on the printer while pressing a button or buttons
These are great help in troubleshooting so it's a good time to locate
them.
Assuming you are running VISTA since this is a VISTA newsgroup, check that
you have the fully featured software for it from the HP website including
the update to stop unexpected uninstallation. Again, it's good to know
where those things are.
