Can't print from Picasa under Crossover Office
 

I'm running Picasa using Crossover Office Standard version 5.0, using a Windows 2000 "bottle".

Picasa works fine for importing, reviewing etc my photos. But when I try to print pictures, the print dialogue box seems to close prematurely (while the progress bar is only halfway across) and then all the printer does is send a sheet of paper through without printing the images, though occasionally with some text (eg when trying to print a contact sheet).

I'm using CUPS to run an Epson Stylus Photo R300. Picasa is finding the printer, as its listed in the print dialogue on Picasa. Other applications print out OK from Crossover Office. Any ideas what the problem might be?
