ports to open for printers

hi all,

 

what ports do you need so you can connect to the printer and print to it

 

atm i have added these ports,

 

IPP which is port TCP 631

 

LPR/LPD - TCP 515

 

Raw - TCP 9100

 

do you need anymore to print to a printer

Re: ports to open for printers

From a print standpoint, those cover most bases assuming the client is a PC.

Airprint/MOPRIA/Cloudprint add more, of course managing the device needs port 80 and 443 (Web server in it)

Bi-Directional communication is via SNMP (161-162)

Re: ports to open for printers

Im seeing a great number of pcs that are accessing something thru ports 443 and 80 from our firewall.  They dont usually access the web page of the machine is there any thing else that uses these ports.  We have also turned off bi-directional communication and snmp to clear up more traffic but these pcs still connect on these ports.  Is there someting im missing?

Re: ports to open for printers

443 is used in a lot of things.

CWIS/EWS

Centreware Web

XDA Lite

EIP apps (App Gallery and App studio obtained)

Xerox direct

Smart eSolutions/Remote Services

Remote Control Panel

Web based Print Driver installer

File repositories (HTTPs as protocol)

Firmware upgrade tool

Only why to know exactly what it is that causes it is to set the printer to Wireshark everything for an hour, then look at that and compare it to the Event logs of the PC/PCs doing it

Re: ports to open for printers

There are many users pcs continued to be connected I dont see why any of the end users would be using anything that has been listed, anything else is disabled from the mfc.  There is someone telling me that the job notification of the driver also use these ports.  This is the only thing that would make sense for the end users pcs  to be connected to the copiers ip address for extened amounts of time.  It also would explain when i turned off the bi directional communication it stopped as well.

 

Thank you for you time and extended list as well
