@JCM111,
 
Thanks for reaching out on HP Support Forums. I’d like to be of your assistance!

I understand that you are having print quality issues with your new HP Sprocket. I will certainly do my best to find you a solution!
 
Splendid effort and fabulous description of the issue before posting. Kudos to you on that score. You are a valued HP customer and it is paramount to assist you here. I take it as a privilege to share this platform with you. I understand you have already performed all possible troubleshooting before posting this on HP Forums. However, I would like to ensure if you have followed these steps before contacting our HP phone support for further assistance. 
 
Let’s first try to update the printer firmware. On your mobile device, make sure it is connected to the Internet, and then open the HP Sprocket app. If there is a firmware update available, a firmware update screen displays. Follow the on-screen prompts to complete the update. Restart the Sprocket and then try printing.
 
If the issue still persists, go to  HP Sprocket Photo Printers – Improving Print Quality and perform the steps mentioned under “What can I do to improve print quality?”.
 
Alternatively, you can go through this link: HP Sprocket Photo Printers – Frequently Asked Questions (FAQs)

The last step is to completely reset the sprocket. On the printer, locate the reset button near the charging port, insert a straight pin into the reset button access point, and then press the reset button for 3 seconds to reset the printer.
Once done, reconnect the printer via Bluetooth and then try to print.
 
If you have followed these steps and still having the issue, I would personally suggest this could be a possible hardware failure with the printer. I would recommend you contact our HP phone support for further assistance.
