.also check if there is still ink on it try printing a self test page

Method one: Print the page from the control panel

1. Load letter, A4, or legal, unused plain white paper into the main tray.
2. Press the OK and Help buttons at the same time and then release them. The self-test diagnostic page prints.

Method two: Print the page from the computer

1. Load letter, A4, or legal, unused plain white paper into the main tray.
2. Open HP Solution Center.
   • Windows Vista: Click the Windows icon ( ), click All Programs , point to HP , and then click HP Solution Center .
   • Windows XP: Click Start , click All Programs , point to HP , and then click HP Solution Center .
   • Windows 2000: Click Start , click Programs , point to HP , and then click HP Solution Center .
3. Click the Settings menu, point to Print Settings , and then click Printer Toolbox .
4. Click the Services tab, and then click Print test page . The self-test diagnostic page prints.

You may clean the cartridge by following the steps given below:
1. Go to the "Lexmark solution center." This can be done by clicking on "Start," go to "Programs" and Lexmark printer group. Click on the "Lexmark Solution center." Next click on the "Maintenance" Tab.
2. Select "Clean and Fix Horizontal streaks." Click on "Print". This will produce a printed page.
The colors that you should see here are black, yellow, magenta (a reddish purple) and cyan (a dark sky blue). You should notice the diagonal lines above and below the solid horizontal lines. These diagonal lines should be solid from left to right with no gaps.
If there are gaps in the lines or the print diminishes across the page, you should run the "Clean Print Nozzle" page a couple more times to try and clear it up. If you still have gaps at the top and bottom, you should "wick" the cartridges by following the steps given below:
1. Please open the "Solution center" again and go to the "Maintenance" Tab.
2. Select "Install color/black cartridge" and remove the cartridge or cartridges from the printer.
3. Get a damp paper towel.
4. Set the ink cartridge right side up on the damp paper towel so that the ink nozzles are against the towel and hold the cartridge in this position for about 15 seconds.
5. Now wipe the print head (on the bottom where the ink comes out) across in one direction only (left to right) until it looks clean.
6. Next dab the cartridge on the towel to make sure that the ink is flowing.
7. Snap the cartridges back into the printer.
8. On your computer, select "Old Cartridge install."
9. Repeat the "Clean Nozzle Page" one more time. If this fails to address the problem the entire procedure may need repeating.

Next, try this printer self-test by following the steps given below:

1. Turn the power to the printer "off."
2. Press and hold the "Paper Feed" button.
3. Press the "Power" button once while continuing to hold the "Paper Feed" button.
4. Keep holding the "Paper Feed" button until one sheet is cycled through.
5. The test is continuous.

The self-test should at least print out a set of either a solid black or solid color bars, if not both (if you have a printer with both color and black installed simultaneously). Should this test fail, try it again without cartridges installed. If the self-test still fails to take paper in and make sounds like the carrier is moving across the paper, this is a hardware issue, and the printer will require service. If the self-test completes without any cartridges installed, run the self-test again with only a color cartridge installed. (If you have both black and color cartridges, after this test, run the test again with just the black cartridge installed.) If you find that either cartridge causes the self-test to fail, please let us know.

If the self-test prints, but has lines or smudges or other print quality issues, let us know.

First of all we need to check weather it's a hard ware problem or software so try to copy something or press a self test page by pressing the x button and the colour copy button together if that prints fine then it means that its a software issue now click on the start button go to control panel then open printers right click on printers and go to properties print test page from there if it prints a blank page then go to the advance tab of properties and go to print processor then select "winprint" and in next line select RAW now try to print
if still the same then check the operating system if its windows Xp then it should be service pack 1 and above if you do not have service pack download the windows xp service and install it now try to print if still the problem persist then please post the exact model number of the printer and the operating system on your computer

Try running couple of these test, to see if it might be another issue.
It should be printing these test at 1500 Line Per Minute... ?
1500LPM is at 10CPI if you have (Font size: 6, 8, 12, 14) it will make a difference.
Change your driver to Generic/Text, rerun your report... any difference?

Does it seem to print the Windows test page faster than the self test print? If so it is probably printing the self test in a higher resolution than the Win test print (Win test prints are usually printed in low res)

Try printing a simple graphic or document from a piece of software. First in DRAFT mode and then in the HIGHEST Quality setting. See if you notice the "jerky" sensation in the DRAFT mode.

It could be normal for you printer.

First of all what is your printer model and manufacturer? What is your computer's operating system? What program/application are you using when printing?
If you are using windows xp or any Microsoft windows operating system, try to print from notepad to check if this happens as well from a generic windows application.

Click Start > Run > type in the box notepad then press ok

from there type a couple of lines about 10 - 15
example:
test
test
test
test
test
test
test
test
test
test
test
test
test

and check if the issue occurs. If it occurred as well in notepad then it is just a format setting in your application.
