# printer_open

(PECL)

printer_open -- Open connection to a printer

## Description

resource printer_open ( [string devicename] )

This function tries to open a connection to the printer devicename, and returns a handle on success or `FALSE` on failure.

If no parameter was given it tries to open a connection to the default printer (if not specified in `php.ini` as printer.default_printer, PHP tries to detect it).

printer_open() also starts a device context.
