Hello Social_GadFly,
Welcome to the HP Forums!
I understand when printing Avery 5160 30/sheet labels, the alignment is off. I will do my best to assist you! Have you tried a different program on your computer to verify if the label is printing off?
I am going to recommend following this HP document on Printing Instructions. Try printing Avery labels from these programs, if they are installed on your computer. I will provide another HP document on Printing on Avery 5160 Labels when Text is not Properly Aligned.
Make sure this printer is plugged into a direct wall, not a surge protector. Also, try aligning the printer again to see if this makes a difference.
Please post your results, as I will be looking forward to hearing from you.
