I've exchanged a few emails with Tim Waugh about this already, but I looked on
the archive and saw there have been 2 similar problems posted to this list, but
with no solutions posted. In addition, there have been posts on
comp.linux.setup with no solution posted.

Anyway, the problem is this. I have an Epson 740 printer, Dell DImension 8100
PC, and Red Hat 7.1. The printer prints fine (text and graphics) when the Dell
is running WIndows 98 (so it isn't the Dell hardware or the cable). It prints
fine when I connect it with the same cable to another box running a Linux 2.4.1
kernel (so it isn't that the driver doesn't work at all with the printer).
However, with the combination of the Dell PC and 2.4.2-2 kernel, nothing
prints. I cannot print graphics NOR text. I can't even get the printer to
produce anything by sending bytes directly to /dev/lp0.
Neither the LP daemon nor driver spew any errors when this happens, so I hooked
up a breakout box to the printer port, and I can see lines going high and low,
but the printer sees nothing. I suspected maybe it was a timing issue, and
tried to use tunelp, but tunelp doesn't seem to affect the operation of the
driver ("tunelp -w 1000000" should, I think, cause data to be sent at one byte
per second, but that's not the case).
I figured since I am the fourth person to note this problem, and since the
other three aren't still complaining, the solution must have been discovered
three times. I would appreciate it if anyone can help me with this.
