How can I print a binary value as hex in TSQL?

DECLARE @binvalue binary(4)
SET @binvalue = 0x12345678
PRINT CAST(@binvalue AS nvarchar)

print master.sys.fn_varbintohexstr(@binvalue)

DECLARE @binvalue binary(4)
SET @binvalue = 0x61000000
PRINT @binvalue
PRINT cast('a' AS binary(4))
PRINT cast(0x61 AS varchar)

DECLARE @mybin1 binary(16)
DECLARE @s varchar(100)
SET @mybin1 = 0x098F6BCD4621D373CADE4E832627B4F6
SET @s = 'The value of @mybin1 is: ' + sys.fn_varbintohexsubstring(0, @mybin1,1,0)
PRINT @s
