Old printers can go bad in a number of ways, including print heads, cartridges, and more. Here are a few troubleshooting steps to go through.
When I try to print something, it comes out blank only in the middle. Yea, my hprinter is very old and I've changed the ink but there's still no solution. Until I get a new one, what's wrong with my printer?
In this excerpt from Answercast #26, I look at an old printer that is leaving a blank area in the middle of the page; this could be caused by a number of different things.
Well, like you said, it's kinda old. There could be a bunch of different things that are wrong with it. You also haven't indicated whether it's a laser printer or an inkjet printer, which can actually make a difference depending on which of those it is.
The kind of scenario that you're describing, where things are blank in the middle of a page, are typically (to me at least) the signs of an aging laser jet printer. It's where I've seen it the most often.
What you have done so far: changing ink, changing the cartridges, changing the laser jet cartridge, those are all good things to do.
The other thing I would suggest you do:
Most printers have a mechanism for cleaning the print head, or for cleaning the drums;
Find and run that.
I would suggest you look up the documentation for your printer. See if you can get that process to happen. It usually requires running a small application on your PC: an application that typically came with the printer. Since your printer's rather old, you may have to go find it on the printer manufacturer's website.
That application will initiate a cleaning cycle on the printer, which will cause it to do a few things internally: to clean print head; and to clean the internal mechanism of the printer.
Outside of that, I don't really have a good solution for you.
That typically takes care of it like nine times out of ten.
That, and changing the inkjet cartridges or the laser jet drum.
Other than that (since you look like you are in the process of getting a new printer), that would be my recommended solution. Printers these days are so incredibly inexpensive that you could spend a lot more time and energy on solving this particular problem than it's really worth.
