Mac OS 10.4.11 using HP5150 printer: not connecting

[chitownchic]

My printer was working fine until I changed the Tricolor cartridge (it's official HP brand #57).  It never printed a test page, and won't do so, even with manual command.  At each attempt at printing out anything (in black/white--b/w cartridge is sufficiently full), computer does not seem to make a successful connection with the printer.  All cords are plugged in properly.  Have tried unplugging and waiting.  No improvement.  I guess the printer diagnostic utility does not work on Macs?  Any suggestions?

I have a 1.42 GHz Power PC G4, in case that is relevant.

Let's reset the printing system:

- Go to System Preferences > Print & Scan
- Hold Option while clicking the '-'- sign below the rectangle listing your printers and select Reset Printing System.
WARNING - this will delete ALL of your printers!
- Select the plus sign to re-add a printer. Select the Defualt tab on the top of the window. Look for the printer, select it and wait until the "Add" button becomes available. Click it.

Thanks so much for responding.  I'm going to save that info for the future.  It is working now.  I suddenly got a flash that maybe the lid to the printer needed another really good hard bonk, or two or three, and that seemed to be what got it going again.  I had tried that before, but not as hard as I did this time.  Finally, it came to.

Thanks again!
