Prints complete lines with occasional lines half height of letter

Printing half a page with an Inkjet machine is not normally a computer issue. So windows 10 would not normally have any effect on the printing for a printer that has been accepted by the Windows 10 Operating System. If there was an issue in the software it would be printing gibberish or not printing at all.

Printing half a page is quite possably something stuck in the printer stopping the ink from getting to that half a page if it is printing down once side but not the other.
Printing half a page being that the top half is printed but not the bottom half (Or the other way around) it could be an air bubble in the feed line which can be cleared with a printhead clean or two.
Printing half a line rather than a full line such as the top half of each letter is clear but the bottom half of each letter is not visable is a blocked printhead. A couple of printhead cleans can also fix this.
Also check to see if the printer is not confused and actually has empty cartridges even if the printer thinks they are full. Brother printers can easily get confused about ink levels. If the cartridges are actually empty, replace them and away it should go again.

Hope that helps

The printer driver is corrupt. Uninstall it from the computer before trying to reinstall the driver. If you don't have the driver CD you can go to HP's website and download it.

To answer your question yes the print wheel can be changed, BUT that is not your problem. The machine needs to be reset or the reset tab needs adjusting.

Background;

When you turn on the machine the print head moves to the right side, the print wheel spins, and the ribbon jumps up and down, that is the machine resetting its self.

I would

1. Power it off and then turn it back on and test to again.
2. If it's still typing the wrong or unreadable letters then turn off the power open the lid. On the bottom of the case there is a metal frame on the right side of the frame you will see a small metal tab pointing towards the print head.
1. (When the machine resets its self, it uses that tab as a reference.)
3. That tab is easily bent which causes the reset to be wrong. Most people can bend it by hand, DON'T use a pliers! The tab can break off completely. It doesn

reinstall the printer driver software it will fix the problem.

This usually indicates a need for a new print cartridge or the printer head is dirty. You can run the automatic printer cleaning utilities. Note: do them several times.
Also, if you are a little handy, use Qtips and rubbing alcohol and clean the print head.

the problem no on your printer, that is your computer problem, when you click print on your computer you have set up size or direction, try it ,

Do a printer utility deep cleaning and possibly be prepared to replace the cartridges

I had the same problem. This is what The Geek Squad recommended:
1) Make sure your ink cartridge isn't low.
2) Go to Setup on the printer, choose Tools, then choose Clean Print Cartridges
3) Then, go back to Tools and choose Align Print Cartridges

This worked for me -- good luck

check the position of your paper drum maybe he is little uper or not on the place.

it could be that the page lenght or papaersize is incorrect, you could try to adjust the paper size to A4 / letter size depending on the paper that is standard
