Envy 4500 not printing every line

[Wazzy2]

I am having the same problem, albeit the printer is printing half a line in places.

if I take out the black cartridge, it prints OK. As soon as I put it back in, the problem reappears.

i have tried cleaning the printhead and cleaning ink smear but still not right

Hey there! @Wazzy2, Welcome to HP forums.

I understand when print from your printer it is printing half lines.

Don't worry I'll try to help you out.

Did you make any changes to your printer?

Does the issue persist when you make a copy from your printer?

Have tried checking with a different ink cartridge?

Have you tried printing using a different brand paper?

Please provide the operating system you are running on your PC to assist you better.

Splendid analysis and remarkable patience shown. It is immensely appreciated.

Try few steps recommended below.

As you mentioned when you remove the black ink cartridge the printer prints fine.

It looks like the black ink cartridge has gone faulty. Replace low, empty or faulty ink cartridges on your printer.

Check the print settings for your print job in Windows.

1.In the program, you are trying to print from, click File, and then click Print. 

The Print window opens.

2.Open the Properties dialog box. 

Depending on the software program, the button might be Properties, Options, Printer Setup, Printer, or Preferences.

3.Depending on your print job, you might consider modifying the following settings:

• Paper Type: If you are printing on photo paper, select the type of photo paper you are attempting to print on.

• Print Quality: If you are dissatisfied with the quality of your printouts, increase the print quality. To print more quickly, decrease the print quality. These options typically include Best, Normal, and Draft modes.

• Paper Size: If you are printing on a different size of paper than you normally print on, select the correct paper size.

• Black and White: If you want to print in black and white only, select the grayscale option.

4.After selecting the print settings, click OK to apply the settings, and then click Print.
