pub struct Printer { /* private fields */ }
Expand description

A Printer object represents a printer.

You only need to deal directly with printers if you use the non-portable PrintUnixDialog API.

A Printer allows to get status information about the printer, such as its description, its location, the number of queued jobs, etc. Most importantly, a Printer object can be used to create a PrintJob object, which lets you print to the printer.

Returns the printer’s capabilities.

This is useful when you’re using PrintUnixDialog’s manual-capabilities setting and need to know which settings the printer can handle and which you must handle yourself.

This will return 0 unless the printer’s details are available, see has_details() and request_details().

Gets the description of the printer.

Returns

the description of @self

Available on Linux only.

Retrieve the hard margins of @self.

These are the margins that define the area at the borders of the paper that the printer cannot print to.

Note: This will not succeed unless the printer’s details are available, see has_details() and request_details().

Returns

true iff the hard margins were retrieved

top

a location to store the top margin in

bottom

a location to store the bottom margin in

left

a location to store the left margin in

a location to store the right margin in

Available on Linux only.

Retrieve the hard margins of @self for @paper_size.

These are the margins that define the area at the borders of the paper that the printer cannot print to.

Returns whether the printer details are available.

Returns

true if @self details are available

Available on Linux only.

Returns whether the printer is accepting jobs

Returns

true if @self is accepting jobs

Available on Linux only.

Returns whether the printer is currently active (i.e. accepts new jobs).

Returns

true if @self is active

Available on Linux only.

Returns whether the printer is the default printer.

Returns

true if @self is the default

Available on Linux only.

Returns whether the printer is currently paused.

A paused printer still accepts jobs, but it is not printing them.

Returns

true if @self is paused

Available on Linux only.

Returns whether the printer is virtual (i.e. does not represent actual printer hardware, but something like a CUPS class).

Returns

true if @self is virtual

Available on Linux only.

Lists all the paper sizes @self supports.

This will return and empty list unless the printer’s details are available, see has_details() and request_details().

Returns

a newly allocated list of newly allocated PageSetups.

Available on Linux only.

Requests the printer details.

When the details are available, the signal::Printer::details-acquired signal will be emitted on @self.

Available on Linux only.

Emitted in response to a request for detailed information about a printer from the print backend.

The @success parameter indicates if the information was actually obtained.

success

true if the details were successfully acquired
