Hewlett Packard manufactures a vast family of computer products, including HP laserjet printers. The all-in-one model offers printing, copying, scanning, and faxing capabilities. The single-function laserjet only offers printing capabilities. Laserjets use specialised cartridges for printing. When you replace your empty print cartridge you can recycle the old one through HP's global recycling service using the tools on HP's website.
Check the box that your cartridge came in for materials that can be used to return it. Your print cartridge box should include a return label. If it does, you can follow the directions on the label to return the cartridge to HP.
Open your web browser and go to HP's product recycling page.
Scroll down until you see the heading "HP Inkjet or LaserJet cartridges" under Global Recycling Services. Select your region from the drop down box on the right and click the "Go" button.
Click on the link that reads "Get HP LaserJet shipping materials" on the right side of the page.
Scroll down until you see the title "Choose your HP LaserJet supply type." Choose what kind of supplies you need and click the corresponding link.
Enter your address and the quantity, or product type, in the supply order window and click "Proceed" at the bottom. Confirm your information and click "Submit" at the bottom of the confirmation window. You can now print your shipping label, or wait for your materials to arrive depending on your selection.
Apply your shipping label to the box and put it in the mail to have it recycled. If you ordered packaging materials you will have to wait to receive them before you can package your cartridge and send it.
