I need to adjust my rule set to allow shared printing, file shares, RDP and pinging. Printing and pinging are not working

My current set:
accept ethertype arp; # so nodes can find each other
drop not ipprotocol tcp;
accept dport 3389; # Destination is RDP
accept dport 9993;
accept dport 445;
accept dport 53;
accept dport 9100;
drop chr tcp_syn and not chr tcp_ack; # No new TCP connections (except RDP)
accept; # Accept what’s left, returning RDP traffic##
