6122 deskjet prints test page fine but only prints one line on the paper for all other print jobs.. what is wrong?

Yes.Tell it to print a dot short word and when it starts printing unplug the power cord so it stops with the printhead somewhere to the left. Then do your cart change. It won' t know you did anything.
The 6122 will print from the HP 920, 930, 932, 940 & 950 drivers also - (which are included with your Windows XP and Vista systems). If you chose the 970 driver it will want a second sheet of paper to print a test page, which you can ignore and it will stop trying. All drivers seem to be the same print quality in my systems. I do not use the 970 or 6122 driver at all so I don't have an ink level monitor or any possible related potential glitch. I wet and slap stubborn old ink cartridges to un-stick dry jets. sometimes I use a small clear silicone tube to suck a bit of ink to get them started as the jet holes need priming sometimes if they are old.

Put back the old cartridges try if print sucsess swap the cartridges find which was faulty.

Go to start->control panel->printer->right click on the default printer(your mut be deskjet 6122)->go to properties..there you will see print test page

in office adjust the page settngs from here file - page setup and make it default

This might be a problem with the connection or corrupted file, try to cancel the print job and try again. -if your using USB connection try to unplug and replug the cable from the PC and the printer side.

I downloaded the driver for hp deskjet 990c and reinstalled my printer manually. It now prints just fine--it just thinks it's a 990c as opposed to the 6122 that it really is.

Hi Ken,
The user manual says this:

1. Verify the following:
There is sufficient paper in the paper tray (at least ten sheets).
The paper tray is not overly full.
The paper stack is touching the back of the paper tray.
2. Slide the paper guides so they fit firmly against the edges of the paper.
3. Press the Resume button to continue printing.

Sometimes my printer won't print if it has too little or too much paper in the slot. It's a relatively common sensor problem.
Try that.

If all else fails, here's a link to the user manual in pdf form:

Good luck
