Thank you for your answer.

I will try to connect only one terminal from each network to the SG2008 switch as well as a printer to see if it prints.

And I will configure the ports according to the vlans of each terminal.

Good morning again

I connected a printer and a computer to two free ports on the SG2008 switch. I set them to two different vlans. One vlan is the one that has the printers, so I put the printer in it and connected the computer to the vlan from where I want to print.

The result was exactly the same, that is, it does not see the printer. It shows the printer as offline.
Well, it doesn't matter that the switches I've used don't support vlan configuration.
Can someone help me with this problem?
Thanks

  @MYN Does it work if you put the PC and the printer on the same vlan?  If so, make sure the printer has the proper default gateway set.

Also, how are you connecting to the printer?  Are you using an explicit IP address or some other method?  Have you tried removing and re-adding the printer since you changed the network topology?

  @MYN I'll say again that some of your switches ARE NOT vlan compliant & will not function in transmitting vlan specific data in your setup.  Without some schematic diagram of how you have things connected, it is not possible to advise you further.

Hello again

When the printers are on the same vlan they work fine.
The gateway is the right one. As you will see in the diagram, there is a problem between vlan10 and vlan20.
When I try to print from vlan10 the printers are offline. I haven't tried uninstalling and reinstalling it. The printers get IP addresses from DHCP and not static ones.

I am sending you the diagram of the network with the switches and ports I use.
This morning the test I did was to put a printer on port 4 and set to vlan20 and on port 5 a laptop and set to vlan10. I didn't use these two ports, but nothing worked before either.
Thank you

So when you add the printers to the workstation, how are you doing that?  If you using some kind of broadcast protocol that won't work across subnets on it's own.

I would try changing the printer settings on one of the workstations to use the IP of one of the printers and see if that works.  If so, you can use dhcp reservation to make sure the IPs don't change.

  Hello again.

I want to inform you that the problem I had with the prints has been solved. 
As user alex789 had mentioned, I reinstalled the printers with the new ip address of the vlan and they are now working properly. 
Thanks for the help.
