          CUT SHEET EMULATION (CSE) AUTOMATIC 2_UP, 3900 DW, PSF/MVS
 
 Cut  Sheet Emulation (CSE), a new feature of 3900 Wide Duplex and PSF/MVS 2.2
 will be available in July.  With CSE, jobs currently  printing  on  cut-sheet
 printers  can  print 2-UP on the 3900 DW1/2 in duplex mode, with no change to
 the job FORMDEF.  The same FORMDEF can be used for printing the job  1-up  on
 the cut-sheet printer, or 2_UP on wide paper on the 3900 Wide Duplex printer.
 The  output, after the 3900 sheets are sliced in half and interleaved by post
 processing, will be identical.  CSE does not force sheet ejects that can  oc-
 casionally create blank half-sheets in FORMDEF-controlled N_UP processing.
 
 CSE  will  require an upgrade to microcode 8.1xx for the 3900 DW2 printer and
 APAR OW19103 to PSF/MVS 2.2.  The 3900 DW2 microcode upgrade will  provide  a
 configuration  option  to enable CSE.   NOTE:  this configuration option will
 have NO effect unless the printer is driven by a PSF that is also enabled for
 CSE: currently only PSF/MVS 2.2 with PTF for OW19103.   Coordination  of  the
 print  driver  and printer CSE code is required for successful implementation
 of this new function.
 
 When CSE is enabled by the printer, PSF will ensure that all  data  sets  are
 printed 2_UP unless:
 
 1.  the FORMDEF for the dataset specifies N_UP.  In this case, the N_UP coded
     in  the  FORMDEF  will  override  CSE.    If  the  FORMDEF  has  multiple
     copygroups, pages printed with a copygroup that specifies N_UP  will  not
     use  CSE,  pages printed with a copygroup that does not specify N_UP will
     use CSE.
 
 2.  or the page size for the dataset is too large to fit on  the  paper  cur-
     rently loaded in the printer.  By default, PSF will not check page size--
     all  data  sets will be printed in CSE unless the FORMDEF specifies N_UP.
     However, PSF/MVS Exit 7 can specify that PSF check page size for  all  or
     selected  jobs.    If  the  page  size coded in the PAGEDEF or in the PGD
     structured field of a MO:DCA page does not fit 2_UP  on  the  sheet,  CSE
     will not be used.  Exit 7 can specify that page size be checked for every
     page  of  a  dataset,  or only on the 1st page and on a copygroup change.
     Datasets with different page sizes can print some pages in CSE  mode  and
     some normal 1-up.
 
 CSE will automatically divide the sheet parallel to the carrier strips into 2
 equal  side-by-side  partitions.    Duplex jobs will print with page 2 on the
 back of page 1 and page 4 on the back of page 3.  The CSE  configuration  op-
 tion  on  the  3900 operator panel allows a choice of different page arrange-
 ments to accommodate different post-processing requirements: left-to-right or
 right-to-left, as well as right-side-up or upside-down (which can  be  useful
 in roll-to-roll post-processing).
 
 When  printing  in  CSE  mode,  each half of the sheet is treated as a single
 physical sheet.  Operations that normally cause sheet ejects (such as  change
 in  medium  overlay,  page copies, suppression, simplex/duplex) will eject to
 the next sheet half.  Multiple datasets printing in CSE mode will continue on
 the next available sheet-half, without forcing a sheet eject.  A single phys-
 ical sheet of paper could contain the job trailer  for  job  1  and  the  job
 header  for  job 2.  If this is not desired, you can force the header page to
 eject to a new sheet by assigning it a FORMDEF that specifies  N_UP  (N_UP  1
 will work).
 
 Note:  FORMDEF  parameters PRESENTATION and DIRECTION, which are normally ig-
 nored on cut-sheet printers, will be honored in CSE mode.  Customers who have
 inadvertently coded FORMDEF options other than  the  default  PORTRAIT/ACROSS
 will  suddenly  see  them take effect in CSE mode.  This could pose a problem
 for customers with incorrectly coded FORMDEFs.  However honoring these param-
 eters will allow CSE to accommodate a wide range of jobs in addition to those
 formatted specifically for cut-sheet.
