Hi folks,
I couldn't make my USB R300 work with bi-directional communications :(
It does print anything but I cant get info on paper out or ink level...
Any clues?

Fábio.
Ps:I'm using Oleg's 1.7.5.9-2

Bidir communications is NOT SUPPORTED by these protocols. Connect directly to your PC if you need this.

Humm thats bad...
I thought that raw communications could be bi-directional, wasnt that the reason to leave the lpr protocol?
I should read old posts for sure ;)

Thanks Oleg, Thanks Antiloop!

Ps: I have used the search Antiloop, but couldn find a answer, sorry.

**Late Edit**
I'm clarified now! For those who want to know why, check out Oleg's place, at http://wl500g.dyndns.org

Actually that's not true. The JetDirect protocol can be bidirectional. It can also include a few more ports.
The p910nd daemon used in the firmware is unidirectional, tho, so I've asked the author if there's
a chance he could make it bidirectional.
He sent me a pre-test of 0.7 with bidirectional support but haven't had the occasion to try it yet
to see if it enables ink-level reporting again.

we know there are a few ways of doing this..

also snmp could be used for this, and yes jetdirect does support bidirectional(otherwise my laserjet2200dn couldn't notify me of things)

please send me and oleg the pre-test of p910nd

Hello,

I looked at the sources for wl500g-1.9.2.7-3c and found
in the src-package the patch for p910nd-0.6,

on the webpage the p910nd-0.7 is available and
there is bi-directional mode support.

Any progress with the program ?
