I think this is specific to High Sierra because I never had this problem before. I eventually (after wasting 4 sheets of expensive paper and lots of ink) printed through Photoshop. No problem there.
The whole adobe package is quite buggy with High Sierra. Takes ages to start Lightroom and photoshop, even with my maxed out 2017 MacBook Pro.
Would be great to see this all disappear in the next update. I have an important shoot next week, hoping the software pulls through.
I am completely unable to print from my Epson WF-3620 printer anymore. I don't print often but it used to work and now it doesn't. I can't specifically tie it to High Sierra update but it's possible. I export a file and print it with other software that works fine. The "Print" option is totally grayed out for me.
I have problems with my Epson R3000 and Lightroom. Since I updated to High Sierra my print presets don't work properly and it's impossible to change from portrait format to landscape format. My black and white prints have a green colour cast too. With Sierra everything worked fine but with High Sierra it doesn't. I do hope there will soon be a bug fix for this.
I recorded a video showing that my landscape format-preset always results in a portrait format-output (print oder pdf) now. Hope the information helps to solve the problem. https://www.dropbox.com/s/bn6qn5t9cwuzvqj/PrintingissuewithEpson%2CLightroomandHie... Of course I cannot show the problem with the colour cast as it is only visible on the print. I can only tell that before High Sierra I got a very neutral black and white-print and now it's slightly green.
I am also having this problem with my landscape presets switching over to portrait when printing. I had to use a portrait preset to get it to work and just contented myself with looking at the image sideways in the print module and turning off my watermark.
Exactly the same - Epson PC-600/Lightroom/Photoshop/ - mostly printing on A3+ Hahnemuhle PhotoRag. Landscape format print settings do not work, however you set page orientation. Once you realise this, ditch the landscape portrait setting and accept previewing at 90 degrees for landscape shots, it ceases to be expensive - just incredibly irritating. I've also found communication between computer and printer (NOT wireless) has become much slower.
