Are the RL2678TW rolls compatible with Brother QL-800 printer? Thanks, Julio

The RL2678TW can be used with a thermal transfer Zebra model but is not compatible with Brother printers. At this time we do not carry any thermal products compatible with Brother printers. Below is a link to our thermal rolls that are compatible with Zebra printer models as well as a link to our DYMO compatible labels page. https://www.onlinelabels.com/roll-labels.aspx https://www.onlinelabels.com/dy-cross-ref.htm

Do these work for a SATO WS408TT Thermal Transfer printer

The RL2678 is a 2.25" x 1.25" thermal label on a 3" core with an 8" outer diameter. Since SATO's WS408 model requires a 1" core roll, this would not be recommended. However, we also offer this label size on a 1" core which can be found at the link below. https://www.onlinelabels.com/products/rl2676

Can these be used with zebra printers? S4M or ZT220

The RL2678TT is a 2.25" x 1.25" thermal transfer label on a 3" core with an 8" outer diameter which meets the specifications for both of Zebra's S4M and ZT220 printers.
