@Anushabekal, Welcome to the HP Support Community!

From which device are you trying to print?

Have you tried printing different photos/pictures and check if the issue persists?

Use genuine HP ZINK photo paper

Upgrade the Sprocket firmware

1. Make sure the Sprocket is on and your mobile device is connected to the Internet.

2. On your mobile device, open the HP sprocket app.

3. Tap the Menu icon , and then tap sprocket.

4. Tap Manage Printers, make sure your Sprocket is selected, and then tap Printer Settings.

5. Under the Status section, locate Battery.

   • If the battery charge is 25% or higher, continue with these steps.

   • If the battery charge is 24% or lower, charge the battery for at least 30 minutes, and then continue with these steps.

6. In Printer Settings, look for a firmware upgrade.

   • If a firmware upgrade displays, tap Get Firmware Upgrade, and then follow the on-screen prompts to complete the update.

   • If a firmware upgrade option does not display, the firmware is up-to-date.

Send a print job. If the print quality is still unacceptable, continue to the next step.

Perform Step 3 and step 4 from this document.

Let me know how this goes.
