Hello,

I am attempting to print data from a variable directly to a CUPS printer - as opposed to a writing a hard-disk file and then sending it to the printer. The reason is because the file system will eventually be a read-only one.

I have created a file handle for the variable that stores the data and populated it. If I print the contents of $variable it is correct.

To send the data to the printer I am opening a file handle for reading and passing it as an argument to a CUPS printer.

However, I am getting a "No such file or directory" error. Yet, the variable and file handle both exist.

Does CUPS not accept a variable tied to a file handle as a parameter or (more likely) am I doing it improperly?

Thanks in advance.

#!/usr/bin/perl -t

use strict;
use warnings;
use Net::CUPS::Destination;

# Define Printer
my $cups = Net::CUPS->new() or die $!;
my $printer = $cups->getDestination("CITIZEN-CT-S801") or die $!;

# Read Data
my($variable)='';

open(my $fh, '>', \$variable) or die "Cannot open file for writing: $!
+\n";

print $fh "Some data 1\n";
print $fh "Some data 2\n";
print $fh "Some data 3\n";

close($fh);

# Print Data
open($fh, '<', \$variable) or die "Cannot open file for reading: $!\n"
+;

if ($printer->printFile($fh, 'jobx')) { print 'Success';} 

else
{
    my $error = $printer->getError();
    if ($error) { print "Printer Error: " . $error . "\n"; }
}
close($fh);

exit;
