+- You need to be in the `kanthaus` network to print.
+- If you use a VPN, you'll need to switch it off for printing.
+- The printer consumes ~15W on standby. It may be left on during the day; it should be switched off at night. The power switch is on the right, vertical edge as you face the printer.
 - On startup the printer may ask for the paper size of a paper tray: choose _"A4 - plain paper"_.
 - Sometimes the printer doesn't wake up from sleep for printing: wake it by pressing the 'power' button on top panel.
 - Pressing the 'eye' button 👁 let's you view the current print job(s) and adjust the paper size.
 - Often pages are printed in _"US Letter"_ format accidentally - but there is only A4 and A3 paper in the printer, so these jobs are rejected with the _"Load paper"_ instruction.
+- Printing a booklet? Install the easy-to-use [bookletimposer](https://kjo.herbesfolles.org/bookletimposer/) (e.g. `sudo apt install bookletimposer`) to convert a linear PDF into booklet format. The default settings are probably what you want (i.e. print 2 pages side by side on A4 -> A5 booklet when folded and stapled)
