I think this may help, but I might be over complicating things, you be the judge:
1. Download Windows Server 2003 Resource Kit Tools
2. Use the setprinter.exe to set the attribute keepjobs
for me, on my vmware setup, it was:
setprinter \jbvmsrvepson 2 “Attribute=|keepjobs”
3. From what I can tell, this keeps the .SPL and .SHD files in the C:WINDOWSsystem32spoolPRINTERS.
4. From there you can download a .SPL converter (ActMask or equivalent) to make PDF’s, txt’s, jpeg, etc.
