Reasons why your HP printer has ink but won`t print

This may seem obvious, but it sometimes happens: first make sure your paper tray has paper in it. Misalignment, clogged printheads, faulty data communication or insufficient ink levels can also be sources of the problem.

Slow prints are usually caused by sluggish or out of date software or a spotty wireless connection. For a quick fix, make sure that all of your printer drivers and printer software is up to date.
Risks of printing too slow

In general, a slower 3D printer print speed results in higher quality. Nonetheless, printing too slowly can cause issues of its own. These issues generally relate to overheating: if the filament stays in the nozzle chamber too long, it can get too hot and cause deformations on the part.

The print spooler slows down if some printers go offline, if some print jobs throw unexpected errors, or if you don`t delete print jobs that you don`t need. To speed the print spooler up, cancel print jobs that are stuck in the spooler.
The Delay Print feature operates within a 24-hour period beginning when you send the job to the printer. If you send the print job after the set print time, the job prints when the set time occurs during the next 24 hours.
The shortcut key to print documents is Ctrl + P.
If your PC or the LCD screen on your printer is telling you that your ink cartridges are full but no ink is passing through to the paper, then it`s most likely that you are dealing with a clogged printhead. Blurry documents and images that appear faded are also signs that it`s time to remove the excess ink.
The most common way that printers are networked is through print servers. Print servers can cause slow printing because they are a single point through which all print jobs are being sent and processed. So if there are inefficiencies in this one point, the printing can become inefficient in the entire network.

Print file sent but no printing occurs
ANSWER : Been working on these since they first were released. Never seen a problem like yours. If it happens again, try doing an engine test, as it bypasses the formatter board. The engine test is located at the right side of the manual tray opening. Look for a hole in the side wall. Stick something like a paper clip into it to actuate the test button. It will then print a lined test page. If it does that, then it points to the formatter board as the cause of your problem.

Prints blank pages, won't print from computer
ANSWER : Don’t know why you replaced the fuser, but assuming you had print before, then it must have been something you did during the procedure. Only thing I can suggest is to recheck your work. Just because you reinstalled a connector doesn’t mean that it is seated firmly enough to work. Any flat ribbon connectors that you removed and reinstalled, check to see that the contacts are all flat and not peeled back.
