Verticle line on left of paper when printing

[Amandalh]

Hello, I've seen posts about this issue but no public solutions posted. 

Printer: HP OfficeJet Pro 7740 Wide

I'm suddenly experiencing a vertical line printed on the left side of my pages. It does this randomly; meaning it only prints on some pages and not on others, but usually the first page. It doesn't matter whether I'm printing from Word, PDF or directly from google docs. I'm wondering if it's a printer driver issue? I need spend 2 hours troubling shooting and downloading multiple drivers for our printers with an agent a couple weeks ago and I think it started around that time.
