[SOLVED] Swapped printers with colleague. Their print jobs are now double printing to both printers.

[TQZ91]

After being swapped, both printers were added by TCP/IP. Is there something I need to "release" from their computer for this to stop happening? Thank you.

Are they truly networked printers (connected to the network router) or shared printers (attached to a computer USB port)?

Make and model printers?

Question: "added by TCP/IP" - does that mean that static IP addresses were assigned to each printer?

Verify that each printer has a different IP address. Were those static IP addresses reserved on the network router for each printer via the printers' respective MACs? The static IP addresses should also be outside of the DHCP IP address range established within the router's configuration settings.

They are networked printers. One is an HP M601 and the other an HP M605.

Yes, static IPs were assigned to both printers.

Both printers are outside of the DHCP range. Both printers were statically assigned those IP addresses.

Each printer seems to think that when a print job is sent that it, the printer, is the one to do the work. Something is being duplicated...

Three things to do:

1) Go to each printer and print out their respective configuration pages.

2) Go to the router's admin pages and determine if there is some listing or diagram of connected devices.

3) Work with some command line utilities:

arp -a via the command prompt may prove helpful. Likewise for netstat.

Powershell can be very helpful: E.g. Get-NetIPAdress

Verify that all the configuration settings and IP addresses are indeed as required and expected.

Next try "reverse engineering" as if you wanted to have duplicate printouts on two printers.

E.g.:

Broadcast, multi-printing.

Pick and chose from the above as applicable to your overall situation.
