Using WUPrint advanced options
What are the Advanced Options in WUPrint? They allow you to change settings such as single vs double-sided printing.
Once you've sent a job to WUPrint, log in to the WUPrint release site. Before you send the job to the printer you can alter these additional settings.
Double-sided print: Change to the desired settings. All jobs sent to WUPrint automatically start as Long-side (most common) printing.
To switch the job to single-sided printing choose None from the list.
