i’ve been cracking my brain about the setting the “1.3.6.1.4.1.11.2.4.3.13.4.0″ value to 2 with an SMTP tool and I just can’t figure it out Could someone help me with this part, step by step. (from a Windows machine). Thanks in advance.

By the way: great job on the application.

Yeah not sure sorry Andre. I guess you’ll just have to give it a go and let us know how you get on

Hi Rhys,
Thanks for the reply. I see Fred uses the Status line as input. And you use Data line as output. What I didnt see is using the Control Line as output. Is it possible? Has anyone tried it?

Regards,

Andre

Hi Andre,

I haven’t done anything except for output so far. But take a look through Fred’s comments below and you should find the info you need.

Thanks for visiting.

Cheers,
Rhys

Hi.
I just found this web and very interested with it. I have some question. Is it possible to use the print server parallel port like LPT port? What I mean is: will I be able to read the status port, write the control port freely like in the LPT?

regards,
Andre

this week my garagedoor remotecontrol was broken, so i implement printer server to remot open trought cellphone
i have tested the busy line as input but when this line whas up the outputs where locked then i tryed the paper out line and it works great with that i can know on my cellphone if the door is open or closed

with this php code:

snmp_set_quick_print(1);
$state = snmpget(“192.168.x.x”, “public”, “1.3.6.1.4.1.11.2.4.3.13.5.0″);
$status=intval($state);
if ($status & 64) echo “”; else echo “”;

Hi Fred.

Thanks again for your comments. This is really great information. The question about inputs has been asked before but I haven’t been able to answer it. I’m planning to add input support to PowerControl for the K8055 so I will try to add input support for Jet Direct too.
Cheers,

Rhys

if you want use the printserver as input you can ask snmp too with this register
1.3.6.1.4.1.11.2.4.3.13.5.0
npPortStatusLines OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-only
STATUS optional
DESCRIPTION
“The state of the centronics status lines from the peripheral. The
value is a bit mask.
Bit Value Signal
0 0×01 nACK
1 0×02
2 0×04
3 0×08
4 0×10 nFAULT
5 0×20 SELECT
6 0×40 PERROR
7 0×80 BUSY”
::={ npPort 5 }
i have tested the inputs respond correctly with snmp client software but i wans’t able to install apache snmp layer on my debian for this time
be carefull by using inputs and outputs while some channels are locking the outputs (select, error and aknowledgement) the others are free i think but i have not tested this configuration)
the next step for me is to add a ne555 on the busy line to have timebase for exemple with 1second timebase if i want to have the 1 bit high for 4 seconds i send 4 bytes and a zero byte
it’s better for automation i need this for my windows shutters
another thing with 3 ports jetdirect

the last zero of snmp adrress ist the port number 0:first 1:second 2:thirdt
(for changing the handshake and asking inputs too)

sorry for my english i’m french, snmp mean simple network management procol
i have used a snmp client softare to change the value of
1.3.6.1.4.1.11.2.4.3.13.4.0 register to 2
this setting would be stored after powerloss

look at google: snmp client , download , give the ip adress of the server and change the value
make only the briges (10 13 15 all connected to 1) on the db25 connector no needs to open the printserver
works great a command the printserver trought asterisk pbx software with my phone by calling a php page so i can switch things simply…
