but this could mess up my system , could not?
i mean i have my printer drivers installed
thanks
Installing the 9800 driver wont have any effect on your driver for the 3880. It will simply add the 9800 to the printer list and provide the ICC files for it. Un-installing the driver will get the printer off the list but will still leave the ICC files.
These are what you soft-proof to when you are sending out to the print service unless they provide you with their own ICC file to use.

the lab prints are different , they don't look like what i see in my eizo (calibrated) and with proof enabled , and they don't like my photos printed with my epson 3880
they told me to make some adjustaments in photoshop to make the lab print match with my epson 3880 and after save the profile
What they are telling you doesn't make sence. Possibly, they may be suggesting that you set up an "action" or "pre-set" that you could apply to your files to make them look like the prints from the 3880 but that is not the correct path to take.
If your monitor is calibrated & profiled correctly and the prints you are getting out of the 3880 utilizing the correct profiles, ink and paper set-up, are a good match for your monitor, it appears that you seem to have your colour management workflow correct.
If the prints you get back from the 9800 are quite different to what you are expecting, you need to check to see if you have soft-proofed correctly (which, if you didn't have the ICC profile, you could not have) or the other print service is doing some automatic corrections &/or colour space conversions inappropriately.
Your print service should be able to provide you the ICC file, they should also advise you what colour space they prefer, while file type they prefer and advise if they do any auto-corrections. You should request that auto corrections be not applied so that they do not alter the image file you have provided and soft-proofed for.
