I made a routine awhile back to display a in hex, it shouldn't be too hard
to make it display hl in hex (if nothing else you could at least call it
twice with h then l).
It probably isn't very well coded, but oh well:

;---------= Display A in Hex =---------
; In: a=number
; Out: a is displayed in hex
; Registers destroyed: af c de hl
dispHex:
 ld c,a
 and %11110000
 rra
 rra
 rra
 rra
 ld d,0
 ld e,a
 ld hl,dispHex_map
 push hl
 add hl,de
 ld a,(hl)
 call putc
 ld a,c
 and %00001111
 ld e,a
 pop hl
 add hl,de
 ld a,(hl)
 jp putc
dispHex_map:
 .db "0123456789ABCDEF"
