Wide format printing

[Styloid]

I'm got no experience of Photoshop.

I work on wide format HP designjet printers and can fix most problems.

One of my customers is struggling to print good images.

They have at least 2 problems.

They are printing to a Designjet z9 and z5200. Both machines are postscript

1) When I print a jpeg from my laptop to the z5200 things come out great.

When they print from photoshop the colours are off.

They are printing PSD files.

2) the image they are trying to print is 550gb. ( Its a 2m x 0.5m long price of wallpaper which is mostly white with a few simple flowers)

When going to print Photoshop gives a warning that the print file exceeds 2gb.

Their IT man says this due to postscript being old tech and not supporting modern large files.
I doubt this. But I fix printers and he's the IT professional

They are printing via an HP Aruba network. Which is very secure and complicated and may be introducing problems.

They are also printing from a clunky old laptop which is flagging up scratch disk full messeges from time to time.

And they insist of printing from PSD files

I looked at the tutorials section but could not find a guide to printing

We support any customers using this printer without issue.

Any advice ?

Hi @Styloid

This is what is called a color management issue.

This link is old yet I believe is still valid.

The color management path that one is taking with the Postscript is different than what the person using Photoshop is doing.
The attached article talks about how to set it up for good color mangement.
Even with postscript, settings are chosen or using default values. That would be helpful to know how the Postcript path is doing it to make sure the Photoshop path is using the same color profiles:

I think this would be a good starting point for you. You can always come back with more questions.
