SUBTTL LPTLAX - Dispatch table
; This module will drive either an LA120 or LA180 hard copy
; terminal as a printer. It is by far, the most simple of
; all the printer drivers for LPTSPL, and as such provides
; the customer with a template for writing drivers for other
; types of terminals (i.e. DIABLOs, etc.).
