Microsoft Windows NT, Beta October 1992 
Problem Printing to Hewlett-Packard DeskJet Printers


The Microsoft Windows NT product group has recently identified a printing  
problem on some systems when printing to Hewlett-Packard DeskJet, 
DeskJet Plus and DeskJet 500 printers from Windows NT.  Error 21 is known 
to occur when attempting to print unless the printer was powered off when 
the system was booted.  The problem occurs due to a failure on the part 
of the parallel port driver to reset if the printer is turned on at 
initialization of Windows NT.  If you print to one of the aforementioned 
printers, you may encounter this problem. 

If you encounter this problem, please take the following steps to replace 
the driver as instructed below.  We appreciate our customers efforts in 
reporting problem areas and encourage you to continue working with us to 
improve the product.  If you continue to encounter similar problems please 
let us know.

To retrieve the corrected files from the WINNT CompuServe forum:

    Connect to the WINNT CompuServe forum, Library 2 where you will find 
    WNT003.ZIP.  This file was created using the PKZIP file compression 
    utility.  You will need the PKUNZIP utility to extract the files to
    a directory on your hard drive.  PKUNZIP can be found as PKZ110.EXE 
    in Library 2 of the IBMCOM forum.  Download PKZ110.EXE and execute 
    the file to extract the PKUNZIP.EXE utility.  Create a directory on
    your hard disk where the extracted files can be placed.  For example, 
    C:\WNT003.  To extract the WNT003.ZIP file, type: 
	PKUNZIP WNT003.ZIP C:\WNT003
    to decompress the files into the directory.  The following files can 
    now be seen:

	PARALLEL.SYS
	README.TXT
