I'm getting a little confused with the P600 firmware choices: AT23FB (released 4/27/15), AT26FB(released 11/26/15) and then there's a release I received from T-Dozer, AT20G4 (released 4/20/16).
I don't know where T-Dozer got that release since it's not on the Epson website.
The first P600 I bought back in July had the AT23FB release. The P600 I bought last month had AT26FB and Dozer is telling me to upgrade to AT20G4.
Now I know certain releases caused errors (for example 0x73, or was it 71).
I'm wonder what releases people are using for their P600 DIY DTG?
