After 802.1X goes to closed mode, laptops work but printers stay offline

Last night the second floor switch ASW2 moved from monitor mode to closed mode: authentication open was removed from every access port. Laptops authenticate with EAP-TLS and work. The four network printers on the floor have been offline since the change. Printer PRN1 is on Gi1/0/22 in VLAN 20, MAC 0026.73aa.10f2. The RADIUS server is Cisco ISE at 10.10.50.11.
