ENSet Status Readback Location Unit Command 16-9
Set Status Readback Location Unit Command 
The Set Location Unit command sets the status location unit to the 
specified value. Location unit is used in conjunction with the location 
type to identify an entity location for a status request (Inquire Status 
Readback Entity command). Note that the unit value is interpreted 
differently, depending on the location type specified.

16-10   Status ReadbackEN
A value of 0 indicates all units of the location type.
A printer reset (
E
CE) returns the location unit to its default value, 0.
The printer retains the location unit setting. If this command is not 
sent to change the setting for an entity request, then the existing 
location unit setting is used.
NoteThe location type and unit may be set in any order. Invalid 
combinations are not determined until the Inquire Entity command 
is received. Therefore, even if the unit value is...

ENEntity Status Responses 16-11
Entity Status Responses 
The status response for an Inquire Status Readback Entity command 
varies depending on the type of entity requested. The status 
responses for font, font extended, macro, user-defined pattern, 
and symbol set are described below.
Font Response 
The status response information returned for font (inquire entity value 
field 0) varies. Depending on whether the printer’s font is a bitmap, 
unbound scalable, or bound scalable, different keywords are...

16-12   Status ReadbackEN
As mentioned, variations in the font response occur as a result of 
the font being a bitmap, bound scalable, unbound scalable, soft 
(downloaded) font, or the location type set to 1 (currently selected). 
These variations include slight differences in the information included 
in the “SELECT=” line, with the addition of different keywords 
(“SYMBOLSETS=” “LOCTYPE=” and “LOCUNIT=”). These variations 
are described in detail in the following paragraphs.
NotesIn the status...

ENEntity Status Responses 16-13
Unbound Scalable Fonts
For unbound fonts, since multiple symbol sets can be associated with 
an unbound font, the “SYMBOLSETS=” keyword is added to list the 
available symbol sets and the symbol set sequence is no longer 
present in the “SELECT=” line. For example, the printer’s internal 
unbound scalable Courier (medium, fixed spaced) font and CG Times 
(bold italic, proportional spaced) fonts would be returned as shown 
below.

16-14   Status ReadbackEN z
For all fonts, if the font is a secondary font, then the “(“ characters 
are replaced by ”)” characters in the “SELECT=” line. 
“LOCTYPE=” identifies the location type of the currently selected font. 
The value returned corresponds to the value field of the Set Status 
Readback Type command.
“LOCUNIT=” identifies the location unit of the currently selected font. 
The value returned corresponds to the value field of the Set Status 
Readback Unit command.
For example, if the...

ENEntity Status Responses 16-15
Font Extended Response  
The font extended response (inquire entity value field 4) provides a 
way to return the name and internal ID number of the font, as well 
as the “SELECT=” line. It is the same as a font status response 
(inquire entity value field 1), in that “SELECT=,” “SYMBOLSETS=,” 
“LOCTYPE=,” and “LOCUNIT=” are returned in the same manner. 
They are not re-described here; refer to the “Font Response” section 
for a description of their operation. However, for...

16-16   Status ReadbackEN
“NAME=” is returned for font extended status requests only. It 
identifies the name of the font, such as, Courier, Times Roman, 
Univers, etc., and its treatment (such as BdIt - bold italic) as listed 
in the font printout. 
For example, the font extended response for the printer’s internal 
bitmap Line Printer font and a downloaded unbound CG Palacio 
temporary font would be returned as shown below.

User-Defined Pattern Response

field 2) lists all of the user-defined pattern IDs (“IDLIST=”) for the 
patterns in the specified location.

The response for symbol sets (inquire entity value field 3) lists all of 
the symbol set IDs (“IDLIST=”) for all of the symbol sets that can be 
bound to unbound scalable fonts in the specified location (type and 
unit).
A symbol set response might appear as shown below.
