Hello all. I appreciate greatly any help any of you may provide. I'm running Windows 10 and Epson P5000. I'm unable to save a user defined size for roll paper. I'm also unable to save a printer preset. If I create either one, after I click OK and move back to the print dialog box, the print size reverts to 8.5x11. If I go back to print settings, the saved size has disappeared. Similarly, if I create a printer preset and then leave the dialog box, when I return to it the preset has disappeared. Epson was no help. I've tried running Photoshop as an administrator without success. I've tried accessing the printing preferences dialog box from the Control Panel, no success. I've tried shell:PrintersFolder, run as admin, no success. I've tried 3 different version of Photoshop, starting with 23.5 and going back to CS5. I found these solutions on the net. I've also looked at Win10 permissions & ownership without turning up anything unusual or wrong. I've also tried logging on as Administrator and also as a different user. I know that what I am trying to do is possible because with a previous printer, the 4880, I had user defined print sizes and a custom default printer preset. The Epson software appears unchanged from that used by the 4880 (of course it is a different version) but I recall that I set up those custom settings without having to jump through any hoops - it was all straight-forward, just click the boxes and it worked. The only difference is I was running Win7 not Win10. I've spent the day chasing down leads on the internet with zero success. If any of you can help I'd be very appreciative. Regards, Tony
