I have Epson 7800 and have driver version 9.33 installed and use Mac os 10.10.2 OS. Trying to print borderless print and have settings in dialogue box set to support printing using custom setting of 24.37 x 36 custom paper size using the roll paper - retain size setting. The printer consistently begins printing the image as an 8.5 11 size. The print settings did not change and the default is set to the custom settings for this printer. I have deleted the printer from the computer and reloaded after ensuring I had the latest printer driver. Any suggestions?
