I had a color issue when I went from High Sierra to Mojave and with the shut-down didn't notice it too much since printing was sporadic for many months. On canvas it really became an issue but the head on my Epson 9900 was having issues with Vivid Magenta clogging so I simply cranked in Magenta layer to get it back until the head died.
Once the head got replaced and I was printing a little more regularly, still had print issues with prints looking somewhat but not quite like I was using sRGB as the ICC profile.
First, I trashed my driver but after I did a screen grab of my settings, just in case. Color was working again but the printer driver missing settings and was totally strange, like part of it was missing. So I trashed the print driver again, downloaded the latest driver from Epson (dated October 2014) and reinstalled the driver. Then I added the printer back and...Voila! All is well! Color is fine, all the settings were intact for my various papers and media combos, and I'm a happy camper.
So, go to your Systems Preferences, then to Printers & Scanners and toss your 3880. Download the current 3880 driver from Epson and install it. Go back to the Printers & Scanners and add your 3880 back to the device list and that may fix your issues.
Hopefully your driver problems will be solved like mine were and you'll be printing up a storm again!
