顺便说一下，我的 sprocket 不会打印我有 2 合 1。当我尝试打印时，它开始打印，但是，

Hi @Raelyn Welcome to the HP Support Community. I’d be happy to assist you with the printing issue.  Let’s try resetting the mobile devices and sprocket -  1) Turn off your mobile device, and then turn it back on.
2) Turn on the Sprocket.
3) Remove the Paper Cover, and then use a narrow object, such as a pen or paperclip, to press and hold the Reset button for 3 seconds until the Sprocket turns off.  4) Turn on the Sprocket. Also, try updating the 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) 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.

 
Hope this helps! Keep me posted.
