Question about HP OfficeJet Pro k550 Printer
Inkjets and Officejets has a foam sponge inside. When the cartridge runs out of ink, there is a tendency for the sponge to dry up and go hard. When you don't fill up your cartridge right away, the ink will dry and clog the micro holes at the outlet of the printer head.
Try to clean the print head properly and carefully. Put it back in and try to print. If same problem occur, then you may need to replace the print head of your HP Officejet Pro K550.
Thank you and good luck!

Are you sure that there's air? Well, i have to ask you few more questions so that we can troubleshoot this better and easier. Is the cartridge new or old? Have you ever refilled it?
Please don't take it otherwise, before i know these, it's impossible to provide the solution for you. Hoping to get a quick and positive reply from you.
