How to setup VLANs / Questions about configuration

Dear Community,
I have troubles setting up VLANs, maybe you can tell me how to do it correctly.
My Infrastructure is:
Modem in Bridge Mode wired to Router
Router with enabled DHCP wired to Port 1 - TL-SG608E
Thus, TL-SG608E works with one UpLink.
Ports 4,5,6,7,8 are connected with different Devices, I would like to Setup a VLAN like:
Vlan1:
Ports: 1-8
Vlan2:
Ports: 4,6
Vlan3:
Ports:
5,6
Vlan4:
Ports:
7,8
Port 6, is a printer, which I would like to use in both VLANs for 2 Pcs (connected to port 4+5)
I have tried:
Untagged Vlan1: Port 1,2,3
Untagged Vlan2: Port 1,4,6
Untagged Vlan3: Port 1,5,6
Untagged Vlan4: Port 1,7,8
How to set up VLAN so that I can use the UpLink (Port1, Internet) for all VLANs?
If I additionally add a VLAN1 with 1-8 then I can access internet, but then the VLAN would make no sense anymore (?) as all ports still are in the same network as the other ports.
My attempts ended up in having no Internet for at least one of the VLANs
Thank you

How to Configure VLAN on TP-Link Switch
Common Questions About 802.1Q VLAN
There should only be 1 untagged VLAN on your port. And based on that, you set the PVID and which determines what VLAN you transmit back.

@BerNet
First of all, thanks for both replys.
I already tried to setup a VLAN like in https://www.tp-link.com/de/support/faq/788/ explained, but it does not work.
I wonder a bit why, cause this is basicly a similar setup (1 Router, 1 Switch with 1 UpLink and 2 Vlans with Devices).
I also dont understand why in this Configuration Schema, Port 1,2 and 3 stays in VLAN 1, cause then the VLANs / Ports are stilll not seperated or ?
You worte, only one Port should be untagged, but which one?
How should I setup the PVID for the Port 6 which is in both VLANs ?
If I do a schema like the example, I soon lose the connection to UpLink when I setup the PVIds like in the example.

Port 6 is what I wanted to say because that's the port you specified with the details.
The uplink should use a tagged VLAN of all other VLANs except for VLAN 1(the default should be untouched).
