=head1 NAME

C4::Print - Koha module dealing with printing

=head1 SYNOPSIS

  use C4::Print;

=head1 DESCRIPTION

The functions in this module handle sending text to a printer.

=head1 FUNCTIONS

=over 2

=item remoteprint

  &remoteprint($items, $borrower);

Prints the list of items in C<$items> to a printer.

C<$borrower> is a reference-to-hash giving information about a patron.
This may be gotten from C<&GetMemberDetails>. The patron's name
will be printed in the output.

C<$items> is a reference-to-list, where each element is a
reference-to-hash describing a borrowed item. C<$items> may be gotten
from C<&GetBorrowerIssues>.

    # set the queue to "file" (or " file", if real queues aren't allowed
