Another question has arrived on our library wall: 
The PCAS printing system is provided by the Bodleian Libraries, so the Library and the School don’t get to choose the software and printers that are provided.
However, this is really useful feedback, we are hoping that PCAS will improve a lot when the software is upgraded later this year. This should resolve the issues that we currently have with intermittent connectivity and PDF printing.
Also if you are having other specific issues with PCAS, please do ask the Library staff – we may be able to help!
