   My router(s) are configured to use DHCP and set with a small range of   
   starting and ending ip addresses. The printer(s)[two printers, each in a   
   different geographic location, one on each router] are assigned a fixed,   
   DHCP dispensed ip address.   
   - Mac Filtering(Access control) is also enabled(for those printers and   
   all other devices) with an 'Allow' control, but new devices are not   
   allowed until configured(assign ip with its MAC, allow in Access   
   Control/Mac filter).   
   - Guest network is almost always disabled unless necessary for visitors.   
      
   The printers are shared on the home network, across my three devices,   
   each device with 3 different but exact same Windows logons(two MSA[mine,   
   spouse]; one Local admin). Other devices(children, grandchildren laptops,   
   phones, iPads with assigned ip address and access control allowed MACs   
   all have use of the printers in each geographic location).   
      
   Never had an issue/problem with any of the printers - one is wifi   
   connected, the other a lan connection).   
      
      
   The only issue that I've come across are iPhones which rotate MAC   
   addresses via their default enabled Private Wi-Fi address. Fortunately,   
   for those, it can be disabled specifically, and only for their wifi   
   connection to my two router/networks and not impacting the use of   
   Private-wifi on their other networks(Home, work[some with extra security   
   control for intellectual property protection]).
