The script executed correctly when printing from a number of different devices on my network. I tried printing from a device which used an unusual username (contained brackets and spaces). The post processing script failed to execute. Modifying the script and using very simple scripts had no effect. I enabled full debug logging in cups-pdf and experimented with ipptool. Could not resolve the issue or find any workarounds. I discovered the bash command used to execute the script contained errors: special characters contained in the username were not escaped. This was causing the script execution to fail due to a bash syntax error. I'm not sure I get what or where the bus is. Was your script not capable of escaping special charachers? Something else? Martin-Éric CUPS-PDF itself is not escaping special characters in usernames when calling external scripts. This needs to be fixed upstream and is on my list. Cheers, Volker
