It doesn''t matter whether I click on "Print One" or "Print..." - the progress bar shows up in the top left of LR (as usual) but only for about 5 to 7 seconds, then it disappears without any "progress" showing. There are no jobs in the Print Queue and the printer is not paused.
I then checked the Epson site and installed the latest drivers for 10.8 (driver version 8.64) and restarted the MacBook Pro and restarted the printer - LR still does not print - same progress bar with not progress.
BTW, when I check the print driver version in System Preferences... > Print & Scan Settings > Options & Supplies, the printer driver version shows as 6.6.Update
I just deleted the printer from the printer list then added it again. The driver version updated to 8.64.
Now it is
- the interface has changed to a rather small Printer Queue window, not the usual, large printer interface showing the supply levels and alerts.
- the icon next to the progress bar in the Printer Queue window has a small "PDF" at the bottom of it. Strange.
- I was printing a "test strip" showing only a portion fo the final photo (I do this to check colour balance and exposure prior to printing a full page – as per darkroom test strips). What printed was not the cropped portion showing in the LR Print Module, but the portion just tot he left of the portion showing in the Print Module. Weird.
If anyone has anything to add or can clarify all of this, I would appreciate it.
