multiple fixes -- now prints successfully to a PT-2450DX.
FIX: job options were being set in GetStatus, now moved to their rightful home in Initialise()
REFACTOR: small mods to structure of Initialise, now uses PT_ERR_* consts, calls pt_Close on failure, exit logic slightly changed.
FIX: debug options should NOT have been set in Hg source (especially SKIP_STATUS_READBACK), now fixed.
