The values entered into the 'Name' field are being validated incorrectly and are not being checked for spaces and quotes.
e.g.  Enter string “user1“ for  the value in the 'Name' field in the first row.
      Enter string “user2” for the value in the 'Name' field in the second row.
      Enter string “user3 “””  ”””” for the value in the 'Name' field in the third row.
and select 'Print' the argument list in the cups error-log is shown below:

 StartJob: argv = "Printer","93","guest","printers.html","1","user1= user2= user3""" """= multiple-document-handling=separate-documents-collated-copies","/var/spool/cups/d00093-001"

The value entered for the 'Name' field should be validated to not contain quotes and spaces, which is not happening here. 

Another observed behaviour is when the values are entered into the 'Name' field the validation takes place only for the first two rows.
e.g.  Enter string  “"user1"“ for  the value in the 'Name' field in the first row.
      Enter string  “"user2"” for the value in the 'Name' field in the second row.
      Enter string  “"user3"” for the value in the 'Name' field in the third row.
and select 'Print' error message shows up for the first and second row entries and the enteries after the second row are not validates

 StartJob: argv = "Printer","93","guest","printers.html","1","user1= user2= "user3"= multiple-document-handling=separate-documents-collated-copies","/var/spool/cups/d00093-001"

The value entered for the 'Name' field should be validated for all rows, which is not happening here.
