connect a printer to nwsp2 usb port

[fvdw]

edit-- fvdw-sl-12-0 and higher has this feature already build in for all devices

With thanks to bozo29 below an instruction how to setup the nwsp2 as print server using an usb printer connected to the front side usb port.

In future release it will be integrated in the firmware.
Currently it is only supported on th nwsp2, we need to test if it vcan be used on nwsp1 and sp8020 as well but there the system memory might be too small.

Instruction for nwsp2

the install can be made using putty

You must have fvdw-sl-11-0 running with the 2.6.39.4 kernel

p910nd.zip

In the attachment you find two files:

p910nd (this is the daemon)
usblp.ko (this is the kernel module to enable printer support on usb port)

Put both in the share with name "public" on the nwsp2 (assume you have this share)
This can be done using windows explorer.

Now access the Nwsp2 with putty.
At the command line give following commands:

install kernel module

Code: Select all

cp /share/1000/public/usblp.ko /lib/modules/2.6.39.4/
chmod 755 /lib/modules/2.6.39.4/usblp.ko
busybox depmod
modprobe usblp


now the module should be loaded check it with command

Code: Select all

lsmod

the list you get should mention the module usblp and that it is "live", this is the output on my system

Code: Select all

# lsmod
usblp 9896 0 - Live 0xbf023000


Next, install the daemon

Code: Select all

cp /share/1000/public/p910nd /usr/sbin/
chmod 755 /usr/sbin/p910nd


create a directory that the daemon needs to run, if you don't make this one it won't start

Code: Select all

mkdir /var/lock
mkdir/var/lock/subsys


Now connect your usb printer and see if it is detected
You can use commands "dmesg" (without quotes) to see if the printer is detected by the nwsp2.
If so then the daemon should also be able to detect it
You can start it by simply giving the command (see internet for more options you can use to start p910nd)

Code: Select all

p910nd -f /dev/usb/lp0


to see if it is in memory and running give the command

Code: Select all

ps -ef

the list that you get should have a line like this

Code: Select all

root      5292     1  0 22:25 ?        00:00:00 p9100d -f /dev/usb/lp0

Now you can try if the daemon can talk with your printer.

using the guide prepared by Bozo29

printer_setup_tutorial.pdf

ps the directory that you created will be deleted at boot and also the kernel module will not be loaded by default during boot. So you will need to repeat that after a reboot. To avoid it we need to change the boot scripts. That will be included in next release.
Also be aware that this folder is created on the relative small system partition. I don't know what the daemon will put in there and if it will be big files or not. If they are big then the partition might run out of space.

Bozo29 successfully installed it and reported that it is working

success and let us know if it works ;)
