I have an epson printer that has been happily printing under RH6.2 via
the USB interface. (with recent 2.2 kernels and the latest lpd RPM)
I have upgraded to 7.3 (that was a saga in itself that I have no desire to
repeat)
and cannot get anything to the printer.

If I use the parallel port it still works (I have two printcap entries),
if I plug it into a Win-98 machine the USB works.
The pll port is far too slow and cpu-intensive for printing photos - I need
the USB.

The LPRng documentation installed in /usr/share/doc from RH7.3 says that
LPRng does NOT support USB printers, but the RH guide (cg chapter 21) says
that it does.
Which is right?

If I try printconf-tui it seem happy until I try the test page, then it
tells me
"There was an error". Thanks. Somebody has been to the microsoft error
message school.
On second thoughts, at least it didn't offer a suggestion that was obviously
wrong.

The printer registers when I plug it into the USB port.
But, there is a message that did not appear under
the 2.2 kernels: the one about "ignoring set_interface...". Is this
important?
The printer driver seems to think the relevant device number has been set.

snippet from kernel log file:
hub.c: USB new device connect on bus1/2, assigned device number 3
usb.c: ignoring set_interface for dev 3, iface 0, alt 0
printer.c: usblp0: USB Bidirectional printer dev 3 if 0 alt 0 proto 2 vid
0x04B8 pid 0x0001
... and later
usb.c: USB disconnect on device 3
printer.c: usblp0: removed

Once I send something to the print spooler, lpc.LPRng reports that it is
printing.
But nothing ever gets printed.
(yes, the old lpd package stuff had been all removed)

Please can somebody point me in the right direction?
