yes, quite normal
the output is always different if you use a PCL vs a PS driver
on mac though, you can play with the color corrections, i believe xerox correction is on by default, you can change to other color corrections/profiles if you want
we have issue with wc 7835 , once we try to print the attached file from windows OS the output color is oky , but when we do that using apple mac OS the color output is not correct
we try this on more than one wc7835 machine with the same result .
