Verifying the GRID files
During physical printer initialization, InfoPrint examines
the contents of the GRID files. If InfoPrint detects
any syntax errors, it reports an error condition and fails to enable
the physical printer. To correct these errors, you must edit the failing
GRID files. For information about what files, lines, or fields are
in error, you must access the GRID error.log file for the physical
printer that is located in /var/psf/PrinterName.
