Hi ArturusDent,
Thank you for using the Support Forum. Please take a look at the solution for sending saved jobs. If this does not help please consider contacting your support centre for further assistance.
I've got a customer with a new WC7845 that wants to print to a mailbox like she did on her incredibly old Canon MFP. I have tried PCL6, PS, and the Global driver. 'Saved Job' seems like its what they want, but it is always grayed out under Job Type.
I set Scan to Mailbox and Print from Mailbox to Enabled in the Remote UI, and also created a separate mailbox/folder in addition to the Default Public Folder.
Any help would be appreciated.
