Printer IrDA Conneciton failure

I have a HP450bci that have IrDA connection.

I'm trying to connect to it via a .Net application. I can detect the printer but when i try to connect to i get the following error:

"No connection could be made because the targer machine actively refused it"
the code is the following:

IrDAClient irdaClient = new IrDAClient("IrDA:IrCOMM");

I have also tryed with the connection string : "IRDA_SOCKET_CONNECTION", but with the same results.

However i can connect to a PC with "IrDA:IrCOMM".


I would like to know what is the connection string to the HP450cbi printer.

Thanks

Re: Printer IrDA Conneciton failure

Thanks, but i already know the URL you send.

The dificulty i have is to know what is the IrDA protocol of the HP450cbi printer.

I have tried several protocols (IrCOMM, IrDial, IrLAP, IrTran-P, IrLMP, IrIAS, IrIAP, IrLPT, IrOBEX, IrLAN, OBEX:IrXfer, Nokia:PhoNet) but all with a refused connection error.

I have already get a connection to a PDA when it is listening to a given protocol. I suspect that the printer i listening to a specific protocol but i don't know which one.

Joao:

It's not much but this is all I could find: http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=bpd50491&locale=en_US&taskId=135&prodSeriesId=81913&prodTypeId=18972
Look under IR Specifications.

Make a great day!
