Following the Tutorial for USB-Printers, I noticed the following problems:

# opkg install kmod-usb-printer
Installing kmod-usb-printer (3.18.23-1) to root...
Downloading http://downloads.openwrt.org/chaos_calm ... _24kec.ipk.
Multiple packages (kmod-usb-core and kmod-usb-core) providing same name marked HOLD or PREFER. Using latest.
Collected errors:
* satisfy_dependencies_for: Cannot satisfy the following dependencies for kmod-usb-printer:
* kernel (= 3.18.23-1-245faaffbc60cabe96a158cae13c1cc3) *
* opkg_install_cmd: Cannot install package kmod-usb-printer.


Installing the driver with -nodeps works, but the module is not found, because it is installed in /lib/modules/3.18.23/usblp.ko, but the running kernel is 3.18.29. After copying the module to /lib/modules/3.18.29/usblp.ko it works.

Recompile the full openwrt will fix such issue, or you can try to directly load module to avoid that warning.
It is openwrt checking the driver version, but should not be a big issue.
