Printing Output from PSD or JPEG?

[Geoffrey]

Hi
Please can you help/advise?

After lots of book and article reading, web and forum searching, I have patently failed to get a definitive answer to this question:
When 'home printing' (currently with an Epson 3000) Is there an output difference between using:
- A saved 16 bit PSD, either a layered or flattened, file and
- A full sized maximum quality, with no further processing, JPEG file, albeit that the inherent nature of the JPEG file will is 8 bit.
I think I vaguely understand that this printer should give a wider colour space than sRGB?, say Adobe RGB, but not sure about ProPhoto RGB? - and is this relevant?
And that any 'home printer' will print to 8 bit.
Is there a relationship between the embedded colour space in a file and the print output?
(As we know, for example, Lightroom operates by default with the ProPhoto colour space, and if the PSD is printed from Lightroom it will also be flattened as LR does not 'do' layers).
Sorry if the query is a little wordy (it is my first post!) - but hope it makes some sense?

Thanks for any help/confirmation.

The short answer is that it depends on the software you are using to print with and whether you have set the printer to manage colour or the software to do the management.

+1 to Paul's comments.

The Epson 3000 is not a photo printer and uses just the four basic C,M,Y and K cartridges, so the best you will do is the AdobeRGB colour space. I don't know how variable the dot size is, but basic printers like yours are likely capable of reproducing perhaps 200,000 distinct colours, so I would be surprised if you saw any difference between an 8-bit or 16-bit image.

I normally print directly out of Photoshop and let it manage colours. I doubt very much that you will see any difference if you printed directly from your PSD file or a jpeg. Again, I suspect your printer is the limiting factor here, rather than anything else.

Hi Paul/Manfred
Thank you for your responses, appreciated.

Sorry for any confusion, but for completeness, the printer is the 'Epson Stylus Photo R3000' it has 9 x Ultra Chrome K3 Inks (including alternative Photo and Matte Blacks). The Maximum Native Print Resolution is stated as: 5760 x 1440 ppi.
I print using Photoshop and Lightroom, set up with the software managing the colours and apply the paper profiles that I had done through the paper manufacturer (I use PermaJet paper from the UK).
Cheers

Manfred - Don't think you've got this right. I have one and it's got 9 cartridges and is sold as: "Epson’s Stylus Photo R3000 sits at the top of its range of dedicated, medium format photo printers .....".

There is no reason to throw out information and print from a jpeg. At most, the results would be similar to printing from the PSD (or other 16-bit) file. At worst, the output would be inferior.
