I did reinstall cups-daemon and cups-core-drivers (2.2.5-2), then removed (purged in fact) fxlinuxprint and then installed printer-driver-fujixerox. But when I try to add printer CP310 it failed because cups claimed "can't copy PPD file". So I removed printer-driver-fujixerox then installed fxlinuxprint. Then cups added a printer CP310 but its printer driver was show as "Local Raw Printer" wrongly. But if I downgraded cups to 2.2.4-7, then cups can add a printer CP310 and its printer driver is correctly "FX Printer Driver for Linux". Further, under this situation, the command cupsfilter -p /etc/cups/ppd/CP310.ppd -m printer/CP310 -e /etc/nsswitch 2>log.stretch produced a line: cupsfilter: Unable to determine MIME type of "/etc/nsswitch". so I doubt this is any problem. I can print a test file with CP310 (under cups 2.2.4-7). It looks to me that cups 2.2.5 has some regression. Thanks for your help and effort.
