The printer is an Epson C86 actually connected to a remote Windows 2000 PC. I print from my local Vista PC and this has worked OK for the last couple of years.
NOW when I send a print from my Vista PC I get a Interactive Service Dialog from the Epson driver (on the vista PC) saying there is "Insufficient disk space", and the document is not printed. This happens whether or not the Windows 2000 PC is switched on.
There is over 1GB of free space on the Windows 2000 C drive, and several GB free on my Vista PC C drive, so the error message is inaccurate.
My guess is that one of the diagnostic programs I was asked to run has changed something on my Vista PC (perhaps a folder removed or its permissions changed, or maybe the privileges of the printer driver changed, etc) which is preventing the epson driver creating or writing to a file, and the driver is just displaying a blanket error message.
I guess if I knew which folders/files the printer driver tries to write to then I might have a chance of fixing the problem.
I noticed that when I send a print from my Vista PC, 3 files get created in C:\windows\temp which are all 0 bytes in length. I don't know whether this is significant.
Has anyone seen this problem before, knows how to fix it, or knows what folders and permissions to check for?
