Each printer will vary, please consult the printer documentation for specifics and requirements.) o rename each extracted setup module to a corresponding: LPS$$UNRECOGNIZED_* 5-47 System Management Information o Insert all of the above-renamed setup modules into a newly-created device control library specific to the new printer: $ LIBRARY/TEXT/CREATE – SYS$COMMON:[SYSLIB]HP4050_DEVCTL.TLB LPS$$UNRECOGNIZED* The above assumes the filename HP4050_DEVCTL.TLB, alter as required. o Set up your DCPS startup procedures to include a search-list logical name such as: $ DEFINE/SYSTEM/EXECUTIVE DCPS_HP4050_LIB – SYS$LIBRARY:HP4050_DEVCTL.TLB, – SYS$LIBRARY:DCPS$DEVCTL.TLB o Supp
