Network Printing with HP deskjet 3600 series

Hi all,

Problem:
OS : Win XP
Platform: VB.NET(Web Application)


My application enumerates all the printers in the network.
Currently there are only 2 network printers here.
1.EPSON TM 210(A) Receipt Printer.
2.HP Deskjet 3600 series.

I added these n/w printers in my local machine .

When i try to access through application it gives :
:Trying to access "\\,,<servername>,<printername>" with invalid
settings


Later added the registry settings as :
"HKEY_USERS\.DEFAULT\Printers\Connections\,,<serve rname>,<printername>"

for both pritners.

Now when i try to print with :
1.EPSON Printer it works fine.
2.HP Deskjet 3600 series it throws exception as:"External component has
thrown an error"

Any resolution regarding this will be very well appreciated.

Cheers,
Bhaskar.
