HP Envy 7855 will not print the lines from graphs or charts

Hi @lilydawn,

 I'd like to help!

To better assist you - 

1) Does the copy print out the same way? 

2) What's the application you are trying to print from? Have you tried printing from a different application or devices? 

While you respond to that, let's print a Print Quality Diagnostic page

Print a Print Quality Diagnostic Report, and then evaluate the results.

1. On the control panel, swipe down to open the Dashboard, and then touch the Setupicon.

2. Swipe up on the display, touch Reports, and then touch Print Quality Report.

Post the Print Quality Diagnostic page here so we can help you further. 

You may also refer to this document with steps to fix " Print Quality Issues" issue applicable for your printer -  Print Quality Issues 

 Also, try updating the printer's firmware - HP Printers - Updating or Upgrading Printer Firmware 

Hope this helps! Keep me posted.
