Hello vetstudent2017, and welcome to the HP Forums, I hope you enjoy your experience!
I see you are running into issues with the quality of your printer output. I would like to help with that today!
Does this issue occur if you make a copy through the front panel of the printer? If so, I would suggest following this document on Fixing Ink Streaks, Faded Prints, and Other Common Print Quality Problems.
As for the delayed network printing, I would suggest utlizing the steps in this document on Wireless printing center Troubleshooting Issues.
Good luck and please let me know the results of your troubleshooting steps. Thank you for posting on the HP Forums!
