One of my users has a Brother HL 1440 that used to work fine when printing through citrix. Now the print jobs either fail or contain invalid characters. I've tried various driver mappings as well as the UPD and can't get anything to work. I'm not positive but it seems like this started after we installed SP4. Any ideas would greatly appreciated. The client is running windows xp / Full pn client 7.0 The server is Win2k SP4 FR2 Thanks
