Pignon et couleur de la photo

 
 
@Agapo
Welcome to HP Forums, 
This is a great place to get support, find answers and tips, 
Thank you for posting your query, I’ll be more than glad to help you out 🙂 
 
As I understand there’s a slight difference in print quality, almost seems like the vintage filter from Instagram is turned on, 😉
Don’t worry as I’ll be glad to help, however, to provide an accurate resolution, I need a few more details: 

Are you using the genuine HP Sprocket photo paper?
Did you charge the printer?
Is the firmware upgraded?

While you respond to that, here’s what you need to do:
 
Step 1: Use genuine HP Sprocket Photo Paper
ZINK® makes custom photo paper for a variety of printers, such as Polaroid, LG, and HP. HP recommends using HP Sprocket Photo Paper for best results. HP cannot guarantee the quality or reliability of non-HP Sprocket Photo Paper. If you do not use genuine HP Sprocket Photo Paper, the steps in this document might not resolve the issue.
To purchase genuine HP Sprocket Photo Paper, go to the HP Sprocket homepage. You can also purchase genuine HP Sprocket Photo Paper from other retailers.
 
If using genuine HP Sprocket Photo Paper did not resolve the issue, continue to the next step.
 
Step 2: Charge the printer
Check the printer battery level using the HP sprocket app to determine if the printer needs to be charged.

Turn on the printer.

On your mobile device, open the HP sprocket app.

Tap the Menu icon , and then tap sprocket.

Tap Printers, and then select your printer in the list.
The printer information screen displays.

Under the Status section, locate Battery.

If the battery charge is 50% or higher, continue to the next step.

If the battery charge is 49% or lower, charge the printer until the Status Indicator light turns green, and then continue to the next step.

Step 3: Upgrade the printer firmware
HP regularly releases firmware updates. Upgrading the printer firmware might resolve the issue.

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

On your mobile device, open the HP sprocket app.

Tap the Menu icon , and then tap sprocket.

Tap Printers, and then tap your printer in the list.
The printer information screen displays.

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 printer firmware is up-to-date. Continue to the next step.

After upgrading the printer firmware, try to print.

If the print quality is unacceptable, continue to the next step.
