General problem with Virtual Printer - first it makes bambulab studio to struggle with connection for printing - couse it sees true bambulab and virtual printer and rotates them ! this lead to communication interruptions and constant asking for ip/access code - when it prints its not clear do it print direct to printer or trough virtual printer ! anyway bambuddy sees the print anyway - but sometimes - says 0 bytes - and in this case all internal functions - like stop print, decrease filament amount, reprint - they DO NOT WORK ! its maybe couse its printed direct to the printer - but as i say u cant guess couse it constant rotates them - like every few seconds.

Yes...you're right, this is the expected behaviour. Since you can reach your printer directly, you don't need VP proxy mode. So the ix is switching it off, or to choose another VP mode.
