@ISA = qw(Exporter);
@EXPORT = qw(&remoteprint &printslip);

=item remoteprint

  &remoteprint($env, $items, $borrower);

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

C<$env> is a reference-to-hash. C<$env-E<gt>{queue}> specifies the
queue to print to; if it is empty or has the special value C<nulllp>,
C<&remoteprint> will print to the file F</tmp/kohaiss>.

C<$borrower> is a reference-to-hash giving information about a patron.
This may be gotten from C<&getpatroninformation>. 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<&currentissues>.

=item printslip

  &printslip($env, $text)

Prints the string C<$text> to a printer. C<$env-E<gt>{queue}>
specifies the queue to print to.

If C<$env-E<gt>{queue}> is empty or set to C<nulllp>, C<&printslip>
will print to the file F</tmp/kohares>.
