Now I have managed to install and configure all like it says in the ubuntu wiki, but command captstatusui -P LBP2900 starts LBP2900 front end that says: printer error, check the devicepath of /etc/ccpd.conf. Now I don't what can be wrong there.

# CUPS configuration file path.

# Printer entries.
# Mapping each "Printer Name" to each "Printer Device Port".
# The "Printer Name" has to be identical to the CUPS printer queue name.
#
# For example, if you prepare a printer named "LBP3200" as a CUPS printer
# queue name, and the printer is connected to the USB port "/dev/usb/lp0",
# you can use the following three lines example just by removing the
# comment symbol "#" of each line.
#<Printer LBP3200>
#DevicePath /dev/usb/lp0
#</Printer>
<Printer LBP2900>
DevicePath /dev/usb/lp0
</Printer>
<Ports>
# Status monitoring socket port.
# Default 39787
