I have a Canon all in one(printer + Scanner) and a samsung laser printer connected to the two different USB ports of the Asus RT AC66U.
If i switch on the Canon all in one before the Samsung laser, the canon becomes the default printer wheareas i want the Samsung printer to remain as the default.
Any ideas on how to do this?
I have DDWRT version v3.0-r43192 giga (05/19/20)
alongwith Entware K3.4
AFAIK, the concept of the "default" printer is not a function of the router or USB. It's a function of the client OS (e.g., Windows or Linux).
By default, the first USB printer is assigned port 9100. All subsequent printers get assigned sequentially from there (9101, 9102, etc.). But the problem is that you can't control which USB port gets assigned to which USB printer, and in which order. So the choice of network port assignment (910x) becomes arbitrary. Even if both printers are ON at the time the process begins, there's still no guarantee which printer gets which port. And when that happens, *then* your references to those ports in the client's OS seem to change the default printer.

To show more than one USB printer on the router, you have to have a second instance of the p910nd running, if memory serves. It does not automatically happen (anymore). _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"

Good point, although I assume if the OP has multiple printers working already, this was already understood.

Right. By default, the first one will be lp0, the additional ones via startup would be lp1, etc. A single printer instance is (now) working again, it's the 2nd printer that goes awry. I found the thread I was thinking about, as I was engaged in the discussion, finally:
