setup remote printer

Hi, 

I tried several time, but failed to get the remote printer work.  I am
wondering if some experts there could give me some advice.
 
I am using RH6.2 with kernel 2.2.19 ( upgraded from 2.2.14-5.0).  I used
control-panel to configure the printer.    

the printcap is:( where the man_hp8k is also our remote printer name)

//////////////////////////////////////////
[root@treig /etc]# cat /etc/printcap
#
# This printcap is being created with printtool v.3.41
# Any changes made here manually will be lost if printtool
# is run later on.
# The presence of this header means that no printcap
# existed when printtool was run.

I tried followings:
//////////////////////////////
[root@treig /etc]# lpr -Pman_hp8k printcap

[root@treig /etc]# lpq -Pman_hp8k

/////////////////////////////////////////////////


why is there no daemon present?  I can see /dev/lp0, but why "lptest >
/dev/lp0" says no such device.


Thanks
