将打印机从一台打印服务器重新映射到另一台打印服务器的 Perl 脚本

Question

我的 Perl 脚本需要更改以允许较长的打印机共享名称。该脚本适用于短打印机共享名。如果您执行 NET SHARE，您就会明白我的意思。无论如何，这是 Perl 脚本：

#this script will not migrate novaPDF pritter
my @printers;
my %PQ2;
my %PQ;
my @NewPQ;
my $NewServer = "MTAPQ10";
my $OldServer = "MTAPQ5";

#Retrive print queues info from the new network print server
print "Generating a printer list on $NewServer..\n";
@NewPQ = `net view $NewServer`;


#Create a required TEMP folder on C:
system("md C:\\TEMP") if(not (-e "C:\\TEMP"));

#Create a VBScripts to enumerate network printer connections
open(OUTFILE,">C:\\TEMP\\EnumPQ.vbs") or die "Unable to create TEMP file";

print OUTFILE  "Option Explicit\n";
print OUTFILE  "Dim objNetwork, objPrinter, intDrive, intNetLetter\n";
print OUTFILE  "Set objNetwork = CreateObject(\"WScript\.Network\")\n";
print OUTFILE  "Set objPrinter = objNetwork.EnumPrinterConnections\n";
print OUTFILE  "For intDrive = 0 To (objPrinter.Count -1) Step 2\n";
print OUTFILE  "  intNetLetter = IntNetLetter +1\n";
print OUTFILE  "  Wscript.Echo objPrinter.Item(intDrive +1)\n";
print OUTFILE  "Next\n";
print OUTFILE  "Wscript\.Quit(1)\n";

close OUTFILE;

#Run VBScript EnumPQ.vbs to generate a list of connected network printers
print "Enumerating local printers...\n";
my @results = `cscript c:\\TEMP\\EnumPQ.vbs`;
print "Local printer enumeration complete\n";

my $FOUND = 0;
#Search for printer(s) on MTAPQ5
foreach my $rec (@results)
{
    chomp $rec;

    next if($rec =~ /nova/i); #bypass nova PDF printer
    #Searching for old server in the form of \\ServerName
    if($rec =~ /\\\\$OldServer/i)
    {
        #Exp rec=\\MTAPQ2\(05-103) HP Color LaserJet 4650 PS 6=
        push @printers, $rec;
        $FOUND = 1;
    }
}

if($FOUND)
{
    &RemovePrinter();
    &AddPrinter();
}
else
{
    print "No network printer on $OldServer found..\n"
}

exit 0; #exit main
#===============================================================================
#Creat a VB script to remove network printer(s)
#===============================================================================
sub RemovePrinter
{

open(OUTFILE,">C:\\TEMP\\rmprint.vbs") or die "Error open outfile..";
print OUTFILE 'Set WshNetwork = WScript.CreateObject("WScript.Network")'."\n\n";

foreach my $printer (@printers)
{
    $printer =~ m/^\\\\$OldServer\\\((.+)\)/i;
    $PQ2{$1} = "old printer";
}

foreach my $shrname (@NewPQ)
{
    chomp $shrname;
    $shrname =~ m/^.+\((.+)\).+/i;
    $PQ{$1} = "New printer";
}

my @PQ2Printers = keys %PQ2;

foreach my $prt (@PQ2Printers)
{
    if(exists $PQ{$prt})
    {
        #Create VB Script to remove the found printers
        print OUTFILE "PrinterPath = \"\\\\$OldServer\\$prt\"\n";
        print OUTFILE "WshNetwork.RemovePrinterConnection PrinterPath, true, true\n\n";
    }
}


print OUTFILE  "Wscript\.Quit(1)\n";
close OUTFILE;

print "Deleting $OldServer printer(s)..\n";
sleep 2;
my $rm_results = `cscript c:\\TEMP\\rmprint.vbs`;
#print "remove result:\n";
#print $rm_results."\n";


}#end sub RemovePrinter

sub AddPrinter
{
open(OUTFILE,">C:\\TEMP\\addprint.vbs") or die "Error open outfile..";
print OUTFILE 'Set WshNetwork = WScript.CreateObject("WScript.Network")'."\n\n";


my @PQ2Printers = keys %PQ2;

#if old printer exists on new server, map it.
foreach my $prt (@PQ2Printers)
{
        if(exists $PQ{$prt})
        {
        #Create VB Script to map the found printers to new server
        print OUTFILE "PrinterPath = \"\\\\$NewServer\\$prt\"\n";
        print OUTFILE "WshNetwork.AddWindowsPrinterConnection PrinterPath, true, true\n\n";
        print "Remapping $OldServer printer to: \\\\$NewServer\\$prt\n";
    }
}

print OUTFILE  "Wscript\.Quit(1)\n";
close OUTFILE;

sleep 2;
my $add_results = `cscript c:\\TEMP\\addprint.vbs`;
#print "Add result:\n";
#print $add_results."\n";

}#end sub AddPrinter

您研究过 CPAN 的各种 Win32 模块吗？

与尝试从 Windows 命令行中获取东西相比，它们提供了更好的界面。

例如 Win32::Printer::Enum 将查找并列出所有可用的打印机，而不是使用：

 @NewPQ = `net view $NewServer`;

并且，您应该能够使用 Perl 的 mkdir 命令，而不是进入系统命令来创建目录。

如果您已经下载了 ActivePerl，请查看它们的 Win32 模块。它可能拥有您需要的一切。
