Struct gtk4::Printer [−][src]
pub struct Printer(_);
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.

Implementations
This is supported on Linux only.
Creates a new builder-pattern struct instance to construct Printer
objects.
This method returns an instance of PrinterBuilder
which can be used to create Printer
objects.

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()
.

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
right
a location to store the right margin in

pub fn hard_margins_for_paper_size(
&self,
paper_size: &mut PaperSize
) -> Option<(f64, f64, f64, f64)>
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.
Note: This will not succeed unless the printer’s details are
available, see has_details()
and
request_details()
.

Returns
a newly
allocated list of newly allocated PageSetup
s.

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