I have had this issue with 2 different computers where I download the L7780 driver which ends up translating to a L7700 driver for my Windows 10 64bit machine and when I go to print a PDF document or an Adobe Illustrator document, the printer spits out a blank page then goes offline and throws all my other printers I have set up on this computer offline. The only way to resolute the other offline printers is to restart my computer. Why would this be doing this? I curretly have no IT person to reffer to and need help. Please.
Thanks for reaching out to the HP Support Forums for a solution to your printing issue.
I understand that you have installed an HP Officejet Pro L7780 All-in-One Printer on a couple Windows 10 computers and when you try to print PDFs the printer prints a blank page and throws the other printers offline. I would like to help.
You mentioed that you currently do not have an IT person. Is there usually IT personell that work on, or maintain the network?
I would start by making sure all the Windows Updates are up to date on both PCs.
