In such cases the first thing that you should do is to call a printer technician and not just any technician but a certified HP printer technician. A certified printer technician will have a complete understanding of the product and the intricacies involved in it. Make sure that the person that you are calling has enough experience and will not cheat you. On the other hand the following points will help you reach to a solution of whether to replace the printer or to repair and stick with it:
If the machine requires consistent repairs then it is about time that you should go for a new one. Sometimes it happens that you have to call the printer technician every month which becomes quite a pain. You should check the machine for a period of four months and if any kind of problem still persists then you should simply replace it with a new one.
It also depends on the type of printer that you own. There are different kinds of printers available in the market and all of them have a different shelf life. It is very important for you to know that the inkjet printers were not designed to be repaired hence whenever an inkjet printer starts giving some technical problem hence you should understand that it is time to change the machine.
If you own a printer that is manufactured with an outdated technology and it has started giving problems as well then you should definitely look for another because it is always better to have a product which is built using state-of-the-art technology.
The last thing which should be considered before deciding whether to replace or repair the printer is the amount of supplies that you have with you. Some people tend to buy a number of printer cartridges before hence you should calculate the amount of loss that you will incur if you will dispose the old printer.
After considering all the above mentioned points it is very difficult that anyone will take a wrong decision.
