                      ' Value9'
                    ],

Notice that 'space Value1' is not the same that 'Value1'. Is that a copy and paste from your output?
If that is the case, $hash1{$y} or $hash1{"$y"} is undefined, since it would be equivalent to $hash1{' Value1'} and the key dereference should be $hash1{'Value1'}

ijsgutenprint

IJSGUTENPRINT(1)					      Gutenprint Manual Pages						  IJSGUTENPRINT(1)

NAME

       ijsgutenprint - Ghostscript driver for Gutenprint

SYNOPSIS

       gs  -sDEVICE=ijs  -sIjsServer=/usr/bin/ijsgutenprint  -sDeviceManufacturer=vendor  -sDeviceModel=name  [  -dIjsUseOutputFD  ] -sIjsParams=[
       key1=value1,keyn=valuen... ] [ options ] [ files ]

DESCRIPTION

       ijsgutenprint provides Ghostscript with a Gutenprint driver, supporting all printers supported by libgutenprint.

       NOTE: ijsgutenprint should never be called directly.  Ghostscript will run it if the IjsServer parameter is set to  IjsServer=ijsgutenprint
       when invoking the IJS driver.

       NOTE:  The  only supported method of running ijsgutenprint is via Foomatic.  Users running ghostscript directly will not be supported.  The
       driver name used by Foomatic is gutenprint-ijs.5.2.

OPTIONS

       ijsgutenprint accepts the following Ghostscript IJS options.  The Gutenprint-specific options are not documented here.

       -dIjsUseOutputFD
	      This option should be specified whenever output from Ghostscript will go to stdout or into a pipe.  It may be specified in all other
	      cases, with only a slight performance degradation.

       -sIjsParams=Option1=Value1,Option2=Value2
	      This parameter contains a single string containing a comma-separated list of sub-options.

       -sDeviceManufacturer=vendor -sDeviceModel=name
	      This  option  must  be  supplied.   There  is  no  default.  The IJS driver requires the vendor (it's part of the protocol), but the
	      ijsgutenprint driver ignores it.

HISTORY

       The Ghostscript stp driver was originally written by Henryk Richter (buggs@comlab.uni-rostock.de), and was integrated into Gutenprint  dur-
       ing  the  3.1  development  series.   Gutenprint (which was named Gimp-Print prior to release 5.0) itself was originally written by Michael
       Sweet <mike@easysw.com>, who released  up  to  version  2.0;  Robert  Krawitz  released	version  3.0.	The  Gutenprint  development  team
       (http://gimp-print.sourceforge.net) now maintains the entire package.

       The  IJS  driver  was  originally written by Russell Lang, and incorporated into Gutenprint (known then as Gimp-Print) in early 2002.  This
       driver corresponds with the IJS protocol 0.32.

       The stp driver is no longer supported as of Gutenprint 5.0.
