Hi Hans,
Here are the changes I've done in the /usr/src/sys/dev/usb/serial/ulpt.c
source. This works both now with my Epson TM-U220B and Xprinter printers.
It can detect either or both in 14.0-CURRENT. So far I haven't encountered
any strange behavior while printing using this ulpt(4) driver.

In the /usr/src/sys/dev/usb/usbdevs, I think there's a need to include the
undefined TM-U220B.
