.SH ARGUMENTS
.TP
.I display
Specifies a pointer to the Display structure; returned from XOpenDisplay.
.TP
.I printer_name
Specifies the name of the printer for which information is desired. If NULL, 
then information is returned for all printers associated with the server.
.TP
.I list_count_return
Returns the number of printers in the list.
.SH DESCRIPTION
.LP
XpGetPrinterList returns a list of printer records where each record describes a 
printer supported by the X Print Server, or NULL if any errors occur.

If 
.I printer_name 
is NULL, then a list of all printers supported is returned. If 
.I printer_name 
is non-NULL, only print records matching 
.I printer_name 
are returned, 
and if no records match 
.I printer_name
, then NULL is returned.

.I printer_name 
is a COMPOUND_TEXT string, and the name and desc fields in the 
returned list will be in COMPOUND_TEXT (note, ISO 8859-1 (Latin-1) is a proper 
subset of COMPOUND_TEXT, so can be used directly). If 
.I printer_name 
is in a code-set that the X Print Server cannot convert (into its operating 
code-set), then the X Print Server may fail to locate the requested printer.   
If 
.I printer_name 
is NULL, then all printer names, regardless of their code-set, can 
be returned, leaving the task of specific printer recognition up to the caller.

When XpGetPrinterList is called, the caller's locale (see XpSetLocaleHinter) is 
included in the request as a "hint" to the X Print Server. If supported by the 
implementation, the X Print Server will use the hint to locate a localized 
description for each printer in the list. If the X Print Server cannot 
understand the hint, the X Print Server will choose a default.
The returned printer list can be freed by calling XpFreePrinterList.

The XPPrinterList structure defined in <X11/extensions/Print.h> contains:
.nf

typedef struct {
    char *name;	/\(** name */
    char *desc;	/\(** localized description */
} XPPrinterRec, *XPPrinterList;

.fi
