Printing protocol

[malay boy]

Guru,
I have LJ8150 which is defined in my server using Jet Admin.
Our network genious need disable some network protocol and
need to know which protocol HP used for network printing.He being so smart that he give
me a list :
ftp-printing
ipp-printing
ipd-printing
ews-config
ipx-config
dlc/llc-config
slp-config
syslog-config
ftp-config
ipp-config

Not being so smart guy , I have to asked the genious people here.

regards

Hi,

Depends on your client software through which you fire print requests.

Are you printing thru lpd or openspool ?

If you are printing from unix then you need not have to use windows 2000 IIS5 IPP (ipp-printing )

OK generally you have to open these ports.

80 or 8000 TCP port for web administration of jetadmin box.

tcp port 443 viz. SSL if want secure web administration through a unsecure network.

161 UDP port for SNMP , if you are monitoring jetadmin box using HP Openview or Ciscoworks .

OK now these are service ports to be opened used for printing.

515 TCP port for LPD daemon
1782 TCP port in case you are using jetsend software

9100 TCP port for LPT:1 9101 for LPT:2 and 9102 for LPT:3

Siva,
Thanks for the reply.We are using lpd to print.

Then ask the network admin not to disable these protocols.

lpd-printing port 515
http port 80 or 8000
https port 443

I just talk to our genious guy.

He was saying that he disable this in the Jet Direct card not port.

ftp-printing
ipp-printing
ipd-printing
ews-config
ipx-config
dlc/llc-config
slp-config
syslog-config
ftp-config
ipp-config

After disable all this thing,lpstat -o was showing the printer down.

p/s:sorry may be my first posting is bit ambigous.

Siva,thanks for the reply.

regards
mB

In case you ever wondered what ports a JetDirect card listens on . . .

http://www.hp.com/cposupport/networking/support_doc/bpj01014.html


20 TCP port for FTP printing. This port can be use to FTP files directly to Jetdirect print servers. HP Jetdirect listens on TCP port 20 for FTP connection requests. Up to three simultaneous FTP sessions can be active at the same time.
23 TCP port for Telnet. This port can be used for remote configuration of the HP Jetdirect device when there are no other configuration methods or to can be used to check the current configuration.
67 and 68 TCP ports for DHCP and BOOTP (they use the same client and server ports). Port 67 is the BOOTP Server and port 68 is the BOOTP Client.
69 TCP port for TFTP. This port is used for configuration and upgrading the Jetdirect firmware.
80 HTTP port for EWS (Embedded Web Server). Newer HP Jetdirect devices have an embedded Web page in the firmware which can be accessed through this port. The Embedded Web Server page allows a user to configure the HP Jetdirect using a supported browser.
161 UDP port SNMP. This port can be accessed by any SNMP Management utility. HP Jetadmin and HP Web Jetadmin use SNMP to configure and query the status of HP Jetdirect devices.
162 UDP port for SNMP traps. This port can be used when the network is configured to capture trap information. Many SNMP Management utilities can be configured to capture traps. HP Web Jetadmin listens for traps in its Alerts configuration on this port.
427 UDP port for SLP (Service Location Protocol). Newer HP Jetdirect devices use the SLP (Service Location Protocol) packet type for advertising their services. Some HP software utilities use multicast and SLP to automatically discovery and automatically install a printer on the network.
443 TCP port for SSL. When enabled, SSL/TLS provides confidentiality, data integrity, and authentication for the communication between a Web browser and the Jetdirect Web server. Although ports 80, 280, or 631 continue for IPP (Internet Printing Protocol) use, other insecure communications are ignored.
515 TCP port for LPD. This port can be used when printing with LPD (for example, from UNIX (R)) or using the Microsoft (R) LPR port monitor. While port 515 is the listen or destination port, TCP ports 721-731 are the source ports on the host machine.
631 UDP port for IPP. IPP is a new Internet Printing Protocol implementation available on newer HP Jetdirect devices. It is used when printing from Windows NT using the HP IPC Internet Printer Connection software.
1782 TCP port for Jetsend. HP has implemented a proprietary process wherein documents or digital pictures can be sent through the network to a printer for automatic printing. This requires proprietary Jetsend software with newer HP Jetdirect devices.
9100 TCP port is used for printing. Port numbers 9101 and 9102 are for parallel ports 2 and 3 on the three-port HP Jetdirect external print servers.
9280 for scanning with the Embedded Web Server (9281 and 9282 for parallel ports 2 and 3 of the multi-port print servers). When attached to a device with scanning capabilities, the Embedded Web Server will allow a user to remotely scan documents.
9290 for raw scanning to peripherals with IEEE 1284.4 specifications. On three port HP Jetdirects, the scan ports are 9290, 9291, and 9292. (When you connect to a raw scan port, the scan gateway sends back "00" if the connection to the peripheral's scan service was successful, "01" if somebody else is using it, and "02" if some other error, for example, the supported peripheral is not connected. Ports 9220, 9221, and 9222 are the generic scan gateway ports currently only usable on 1284.4 peripherals.)

I think, at the minimum, you need:

TCP/IP PRINT OPTIONS
9100 Printing : Enabled
LPD Printing : Enabled
