Detailed Description

Print support under Unix/Linux.

Class Fl_PostScript_Printer is implemented only on the Unix/Linux platform. It has no public constructor. Use Fl_Printer instead that is cross-platform and has the same API.

Member Function Documentation

const char* Fl_PostScript_Printer::class_name ( )

inlinevirtual

Returns the name of the class of this object.

The class of an instance of an Fl_Device subclass can be checked with code such as:

   if ( instance->class_name() == Fl_Printer::class_id ) { ... }

Reimplemented from Fl_PostScript_File_Device.

int Fl_PostScript_Printer::start_job ( int  pagecount, int *  frompage = NULL, int *  topage = NULL  )

virtual

Starts a print job.

Parameters:

[in]	pagecount	the total number of pages of the job
[out]	frompage	if non-null, *frompage is set to the first page the user wants printed
[out]	topage	if non-null, *topage is set to the last page the user wants printed

Returns:

0 if OK, non-zero if any error

Reimplemented from Fl_Paged_Device.

Member Data Documentation

const char * Fl_PostScript_Printer::class_id = Fl_Printer::class_id

static

A string that identifies each subclass of Fl_Device.

Function class_name() applied to a device of this class returns this string.

Reimplemented from Fl_PostScript_File_Device.
