Prints a document by spawning the external command stored in |
|
| 71 |
C<$self-E<gt>printer_command> and sending content to it. |
|
| 72 |
|
|
| 73 |
The caller must provide either the content to send to the printer |
|
| 74 |
(parameter C<content>) or a name to a file whose content is sent |
|
| 75 |
verbatim (parameter C<file_name>). |
|
| 76 |
|
|
| 77 |
An optional parameter C<copies> can be given to specify the number of |
|
| 78 |
copies to print. This is done by invoking the print command multiple |
|
| 79 |
times. The number of copies defaults to 1. |

SL::DB::Printer: »Dokument an Drucker schicken« zentralisiert
Die neue Funktion print_document übernimmt das Spawnen des externen
Prozesses und schickt das Dokument an den Drucker. Das Dokument kann
entweder direkt als Inhalt oder als zu sendender Dateiname übergeben
werden.
