Any solutions to Snow Leopard 10.6.1 R2880 total failure on iMac

Question

Everything was fine on Snow Leopard 10.6, but now - on 10.6.1 - I can print nothing to the Epson R2880 from my main desktop machine. When I went to print, the Epson Printer software had been removed and I had a message that new printer drivers should be downloaded from the manufacturer.
Having done this, I had various error messages culminating in the one shown below.
Hours of searching the forums, and telephone help from first Epson then Apple, have not solved the issue. in spite of removing the printer, uninstalling Epson software, drivers and library folders, reinstalling current drivers, making sure Rosetta is loaded et cetera.
Strangely, the printer works OK from my laptop, which is running 10.6.1 and identical Epson drivers.
The problem is caused it seems by rastertoescp in /Library/Printers/EPSON/InkjetPrinter/Filter/rastertoescp.app/Contents/MacOS/ra stertoescp
Epson blames Apple, and Apple tech support has tried all it knows or can think of. The case has been escalated,and I should hear back 'within the week'. In the meantime, can anyone help?
The error log file, which has gone to Apple, starts as follows:

Click on the file it downloads and uninstall Gutenprint.
2. Power off the printer
3. Remove the printer driver from Print and Fax
4. Delete the Epson Folder from the following location
