Printer Setup

HP Recommended
HP Designjet T790ps 24 in
Microsoft Windows 10 (64-bit)

I recently acquired a plotter for my office. I don't print much but really need to be able to every once in a while. 

 

It prints horizontal lines (ones in line with the printer) straight but diagonal and vertical lines are broken. It is very consistent. I have bought new printer heads, cleaned it, and aligned printerheads. Below is a snip of what is going on. #1 from printer and #2 from autocad.

Thank you for any help.

Have you performed the paper feed calibrations. I do not see a picture attached so I am kinda guessing. You may also need to print at a higher quality setting depending on media.

If you find the information provided useful or solves your problems, help other users find the solution easier by giving kudos and marking my post as an accepted solution.

Here's an update. If I save my Cad drawings as a PDF and use a thumb drive directly in the printer, it prints perfectly. If I print in any format from my computer, I get the hashed lines.
