Kprinter has stopped working - Unable to start child print process

[Andrew Myers]

For some reason Kprinter has stopped working correctly. the error 
message is:

"Unable to start child print process. Check the command syntax: 
cupsdoprint -P 'Oki' -J 'envelope.ps' -H 'localhost:631' -U 'andrew' -o 
' copies=1 multiple-document-handling=separate-documents-collated-copies' "

If I try to run the command at the command line I get:

"This utility doesn't support printing from STDIN "

Cupsd is running, I can look at the admin system on the web, the test 
pages print correctly through the KDE control module, and there are no 
apparent logged errors, just the error marked above. I can print the 
file from the command line using lp/lpr.

If I change the print system to lpr I get a similar error message from 
Kprinter.

"Unable to start child print process. Check the command syntax: 
/usr/bin/lpr -P 'Oki' '-#1'"

Googling indicates that it may be something to do with an update I may 
have installed recently, but restarting the system certainly makes no 
difference.

Does any one have any ideas as to why this might occur?

All the best
