Printer server not working

[yhq34]

Hi,

I connected an epson printer to the openwrt router. but I can't print at my computer via it's share printer.
conf:

uci show p910nd
p910nd.@p910nd[0]=p910nd
p910nd.@p910nd[0].enabled='1'
p910nd.@p910nd[0].device='/dev/usb/lp0'
p910nd.@p910nd[0].bind='192.168.1.43'
p910nd.@p910nd[0].port='0'
p910nd.@p910nd[0].bidirectional='1'
root@OpenWrt:~# ls /dev/usb
lp0

can't print ?
can't access ?
can't see it at all ?

[yhq34]

there is no place I can see the printer in the router's web page.
I just add the printer in the Windows like below guide;
https://openwrt.org/docs/guide-user/services/print_server/p910ndprinterserver
Configure clients
Windows

I meant from the clients, not the router. I assume you have installed all the required packages on the router.

You probably have to install the luci-app-p910nd package to get the UI in Luci.

[yhq34]

I already installed the printer from the clients.

[frollic]

wow, go easy on the information sharing ....

and you've installed all the required packages on the router side ?

[yhq34]

sorry for that，
already install kmod-usb-printer and p910nd

[frollic]

well,

if you've followed the router side instructions, verify that you can connect to the p910nd using telnet (in for instance putty).

[yhq34]

tenet to router's port 9100 was OK.

[frollic]

then you have to start studying the logs for the p910nd.

[yhq34]

system log full of below two lines:

Thu Feb 11 19:00:49 2021 lpr.err p9100d[1300]: /dev/lp0: No such file or directory
Thu Feb 11 19:00:49 2021 lpr.err p9100d[1300]: /dev/lp0: No such file or directory

will try opening later

[frollic]

well you wrote /dev/usb/lp0 in the 1st post, so there's a configuration error somewhere.

I'm sure you can figure out the rest.

(or be lazy, and create a softlink between the two locations)
