I don't think so. You would have to compile a new firmware that supports USB host protocol and USB printers. And you would have to add drivers that translate the USB data to TCP/IP (or UDP/IP) and drivers for your PC. Maybe even do hardware modifications.
Have a look at the new 7170. It is the latest model in the FBF series and includes most of the features of the 7050 plus
USB host support for one non-GDI-printer and three FAT-formatted USB hard disks
a four port LAN switch instead of two ports
hardwired switch for WLAN on/off
USB-client support has been kicked out - no more room left for the port.
