When I create multiple lines in Photoshop only one line prints

[DaveRado]

I am using PS CS6 v13 with Windows 10.

If I create more than one line in Photoshop using the Line Tool, only one of the lines prints. All of the lines are visible in the Photoshop file, but even in Print Preview only one line is visible - as you can see in the attached screen capture in which there are four grey lines in the Photoshop file forming a box, but only the bottom line is visible in the Print Preview, and only the bottom line prints.

What's going on and how can I fix this?

Can you select one of the non-printing lines with the Path Selection tool (black arrow) and share a screen shot that includes the options bar and Properties panel

Hi Jane

Screen capture attached.

PS - the printing and non-printing lines have identical properties to each other.

PPS - I forgot to say @jane-e in my previous replies so I'm including it here just in case Jane wouldn't have been notified of my replies otherwise?
