        PSF/6000: ENHANCED TO SUPPORT POSTSCRIPT LEVEL 2 & PCL5E INPUT


 The  PostScript Level 2 and PCL5e transforms for Print Services Facility/6000
 Release 2, described in announcement letter 294-793, are now available to li-
 censed PSF/6000 customers in APAR IX51086.

 With this APAR, PSF/6000 Release 2 now supports PostScript Level 2  and  con-
 tinues to provide the fastest PostScript printing capability available today.
 The  addition  of  the  PCL  transform  enables customers to print PCL5e data
 streams (including GL/2 plotter language) to the wide range of printers  that
 PSF/6000 supports.

 These new functions have been added in response to customer requests.  Inter-
 ested  customers  may obtain the Program Temporary Fix (PTF) U437972 for APAR
 IX51086 through their normal support channels.

 Transform Limitations:
 ______________________

 o   Both the PCL and PostScript transforms  discard  imbedded  device-control
     statements,  such  as  those used for duplex or bin selection. If needed,
     these parameters should be specified in the FORMDEF or using  the  appro-
     priate  parameters  on the command line or through SMIT. (Note that a PCL
     or PostScript job that includes device-control statements to  dynamically
     switch  bins  or between duplex and simplex within a job will not provide
     the same results through the PSF/6000 transforms as it would on a  native
     PCL or PostScript printer.)

 o   Resolution  conversion algorithms may yield degraded appearance when used
     to reduce the resolution of a datastream. For this reason the PCL  trans-
     form  may  degrade  the  appearance of higher-resolution datastreams when
     used with 240-pel printers.  The customer should verify that print fidel-
     ity is satisfactory.

 o   There are subtle differences between PCL4 and PCL5e when it comes to han-
     dling fonts, and while many PCL4 files will work with the transform, some
     may not produce the expected output.

 o   The PostScript interpreter will not properly process embedded binary  ob-
     jects.    If  you are using a driver that generates binary PostScript ob-
     jects, either disable this feature, or use a  more  generic  driver  that
     does not create binary PostScript objects.
