Hello
I found the option of the printer to set the negotiation, set it to auto and now does not lose packets via ICMP (from desktopA to the printer).
I also verify that setting autonegotiation = not in the printer, the switch is set as Half-duplex.

I went back to configure the network as before.

switch B (1GB) <---> switch A (100Mb)  -----> Printer
                        |
                        |  ---> Desktop Z, X, Y
                        |  
                        | ---> Some desktop and server



Now "tcp.analysis.retransmission" the desktop Z, has a loss of 0.25%, while desktop Y, X has a 0.9%
I guess that 0.9% should remain much .. but I think I'll leave.

I thank you all the writing in this post, I really learned what I owe to you.

Greetings.
