lprng and tty's

I have a problem making lprng work with a printer attached to a serial
line. First I had to change the permission to root.lp, this was simple and
sensible IMHO. But then it refuses to print, only sometimes the old needle
printer spews out a few characters or a newline.

I tried to fiddle with the :ty=: settings in /etc/printcap, but to no
avail. Just cat file > /dev/ttyS3 works just fine.

This is the output of stty -a < /dev/ttyS3:
speed 9600 baud; rows 24; columns 80; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
eol2 = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W;
lnext = ^V; flush = ^O; min = 1; time = 0;

isig icanon iexten echo echoe echok -echonl -noflsh -xcase -tostop -echoprt
echoctl echoke

I now print to /dev/null using a filter that cat's to /dev/ttyS3, but this
is a bad workaround.

Old lpr had no problems just specifying lp=/dev/ttyS3

What did I do wrong?

Nils
