Very Weird Printing Issue in PS

I've been at this for quite a few years, but this is a new head-scratcher to me.

A colleague at our studio cannot print any of his PS files correctly-- they come out scaled correct, but everything is cropped in the printer as if letter-size paper was chosen.
Details: He's on a new MacPro laptop (Yosemite) using PS cc. The problem occurs whether the file is sent to my Epson inkjet via ethernet, if I print a copy of the file from my MacPro (Mavericks & PS6) directly to the Epson, if he sends it to a Xerox Phaser laser, and it even occurs if he's printing a screen capture via Preview!

I've disconnected the network and printed from my computer, but it still came out printed in a 8.5 x 11 area on a corner of a 17 x 22 sheet. Problem is the same with choosing Tabloid size paper.
Finally, I imported his file into LR, printed from there and voilà, it printed correctly. An issue with his version of PS? Good luck getting that corrected...

Any help greatly appreciated!

Hummmm..........

Click on the crop tool and see what shows up. Go to VIEW > show all and see if anything shows up which may be cropping it. Go to SELECT> DESELECT to make sure the whole photo is selected. Is the image in layers? If so, flatten it and then print.

Thanks for that (Gil?). Nothing shows up cropped and we've been printing flattened files.

You've looked at every print setting, advanced tab, etc. in the printer dialog box?

I reread your initial post and realized I had misread it, initially thinking that the image was cropped. I see now it is merely reduced in size. I really think the problem must rest within the printer dialog boxes, as I don't think any image is locked into any particular size until it gets to the printer dialog.

Sorry if I didn't explain it well enough. The printed image is indeed cropped. It is SCALED correctly, but it is not printing the entire image, just an 8.5 x 11 section of it. The small part that is printed is at the scale/size it should be, we're just not seeing the whole thing.

I've been printing PS files, flattened files from originals often containing hundreds of layers for well over a decade, custom and standard sizes through multiple versions of PS and never had an issue like this. We've gone over every dialogue option I can see and have ever used.

To make it worse, it happened to me once recently on a file of mine that I was printing. I printed it again, and everything since has been fine. That made me wonder if it wasn't some server issue, but when I printed my colleague's file with the ethernet disconnected, it still had the problem.

Oh, I see. My initial interpretation was correct. Maybe someone else will have some suggestions.

Did your colleague with the new machine download and install the drivers for the printers from the manufacturers' websites? This is preferred to the drivers that ship with the Mac OS. Did the new machine ever print correctly?

What version of PS?

Yes, that was one of the first things I had him do. Remove the printer from his OS printer list, uninstall/remove the driver, get the newest version from the Epson site and add the printer back on to his list. They even tried installing an older driver version.
And it's more than one printer-- the issue first came up on our Epson 3880 inkjet, which has been working just fine for me for a long time (with that one glitch), and then showed up on our laser printer, a Xerox Phaser 7800GX. I have no problem with either, but another colleague had a similar temporary problem that resolved itself after a short while.
He's on the latest cc.
Weird that hid file printed fine from my LR5-- Guess we'll just wait for IT to show up and hope they have a clue. I don't want to be doing all his printing...
