I need to get the factor score weights used by Mplus to calculate the factor scores.
I need to give the factor scores' computation formula to a colleague so that she can estimate the factor scores from each of the item scales. In SPSS AMOS I just ask for the factor score weights. But I can't find a way to do it in Mplus. Is it possible? If yes, how?

See the FSCOEFFICIENT option in the user's guide.

Why don't you just save the factor scores in Mplus.

Dear Linda,
Thanks for your prompt response.
We are giving a formulae to colleagues who use our scale for them to calculate the scores for each factor.

... but, I still have a problem: The FSCOEFFICIENT is "It is available only for
TYPE=GENERAL and TYPE=COMPLEX with all continuous dependent variables". Thus I got this error message

*** WARNING in OUTPUT command
FSCOEFFICIENT is not available for analysis with at least one categorical
dependent variable. Request for FSCOEFFICIENT is ignored.

All my variables (itens) are ordinal (3-point rating scale) thus I am using CATEGORICAL ARE ALL and WLMSV...

Is there a way to get these factor weights from Ordinal variables? Some type of ordered logistic coefficients?

You cannot compute factor scores for categorical outcomes by hand. An iterative process is used.
