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 out of range, the unit 
is set to that value so that an appropriate error response is sent 
when the Inquire Entity command is received. 
Inquire Status Readback Entity Command  
The Inquire Entity command identifies the entity type and causes the 
printer to create a status response for the entity specified in the status 
readback location (type and unit).

The entity status responses for the value field parameters vary 
depending on the setting of the location type and location unit (refer 
to the Set Location Type and Set Location Unit commands described 
on the preceding pages).
The entity status and error responses are described on the following 
pages. 
						

							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 returned. 
The response is also somewhat different if the location type is set to 1 
(currently selected, as explained in more detail later). The list of 
possible keywords for a font request is shown below.
SELECT= 
SYMBOLSETS= 
LOCTYPE= 
LOCUNIT=
An example of an inquire entity font (entity type 0) status response is 
shown below. Notice the variation in the keyword lines for the three 
fonts, listed in order below:
Internal, bitmap, Line Printer
Internal, unbound scalable, CG Times italic 
Downloaded, bound scalable, (CG Palacio)
Font status:
PCL 
INFO FONTS 
SELECT=“(8U(s0p16.67h8.5v0s0b0T”

SYMBOLSETS=“0D,0I,0N,0S,0U,1E,1F,1G,...” 
SELECT=“(1U(s1p__v0s0b4111T(21X”
   M
In a font status response, individual fonts are identified by the 
“SELECT=” keyword line, as shown in the example above. This 
line identifies the font by specifying the font selection characteristics 
(symbol set, spacing, pitch, height, style, stroke weight, and 
typeface). The characteristics are listed as they would be sent to 
the printer to select the font (in priority order, highest priority to 
lowest). “SELECT=” is returned for all font types. 
						

							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 response, an escape character is represented by the five 
characters: “&”.
Keywords which follow a “SELECT=” keyword apply to the font 
identified by that “SELECT=” keyword. 
Bitmap Fonts
For bitmap fonts, the “SELECT=” line is returned (which identifies the 
font selection characteristics as described above). For example, the 
printer’s internal, bitmap, Roman-8 Line Printer font would be 
returned as shown below.
PCL 
INFO FONTS 
SELECT=“(8U(s0p16.67h8.5v0s0b0T”
Also see soft font description below.
Scalable Fonts   
For bound scalable fonts, two underscores, “...s 1 p __ v 0 s...,” in 
the “SELECT=” line indicate that the font is a bound scalable. In 
addition, only the relevant characteristics are listed. Depending on 
whether the font is proportional or fixed spaced, only either height 
or pitch is listed. For example, the printer’s internal scalable Symbol 
font (proportionally spaced) would be returned as shown below.
PCL 
INFO FONTS 
SELECT=“(19M(s1p__v0s0b16686T”
Also see the soft font description below. 
						

							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.
PCL 
INFO FONTS 
SELECT=“(s0p__h0s0b4099T” 
SYMBOLSETS=“0D,0I,0N,0S,0U,1E,1F,1G,... 
SELECT=“(s1p__v1s3b4101T”
SYMBOLSETS=“0D,0I,0N,0S,0U,1E,1F,1G,...”
Soft Fonts 
For soft fonts (bitmap, bound scalable or unbound scalable), the font 
ID number is also included at the end (a font downloaded with an ID 
of 27 would be presented as “ ...(27X ” ). For example, a 
downloaded bitmap Courier with a font ID of 39 and a downloaded, 
unbound scalable, Dom Casual typeface with a font ID of 78 would 
be returned as shown below.
PCL 
INFO FONTS 
SELECT=“(8U(s0p10.00h12.0v0s0b3T(39X”
SELECT=“(s1p__v1s0b4148T(78X” 
SYMBOLSETS=“0D,0I,0N,0S,0U,1E,1F,1G,...”
Location Type 1 (Currently Selected) Font 
For a status location type 1 (currently selected) font, only a single 
font, the printer’s currently selected font, is returned. The keywords 
and data returned are described as follows.
z“LOCTYPE=” and “LOCUNIT=” are returned after the “SELECT=” 
line for each font.
z“SELECT=” line changes for bound and unbound scalable fonts.  
 For all scalable fonts, the actual size (either height or pitch) is 
listed in place of the underscores.
 For unbound scalable fonts, the symbol set currently bound 
to the font is listed.  
						

							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 printer’s currently selected font is a bold 14 point 
Presentation bitmap font selected from a cartridge, and a font entity 
request with the location type set to 1 is made, the response would 
be returned as shown below.

scalable Dom Casual font with the following characteristics:
zdownloaded (font ID of 78) 
ztemporary

zsecondary font 
z18 point
If an entity request is made with the location type set to 1 (currently 
selected), the following response is returned.

							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 a font extended 
request, two additional keywords, “DEFID=” and “NAME=” are 
returned as described below.
“DEFID=” identifies the font’s internal ID number. This is the number 
which appears on the font printout. It is the number used to select the 
font as the default font from either the printer’s control panel or from 
PJL (refer to the Printer Job Language Technical Reference Manual 
for information on PJL font selection). The “DEFID=” number consists 
of two parts, a location and an ID number, such as “I 21,” where “I” is 
the location and “21” is the font’s internal ID number. The possible 
locations are listed below:
NoteThe cartridge (Cn) and SIMMs (Mn) location identifiers are printer 
specific. Refer to Chapter 1 of the PCL 5 Comparison Guide for 
printer-specific values for “n.”
Since temporary soft fonts do not have an internal ID number (they 
cannot be selected as the default from the control panel or PJL), 
NONE is returned as their “DEFID=NONE”.
The font’s internal ID number is assigned to fonts by the printer. This 
number is different than the soft font download ID number assigned to 
a downloaded font using the Font ID (E
C*c#D) command.  Table 16-5
I - Internal
C  -  Cartridge - single cartridge printers
Cn  -  Cartridge - multiple cartridge printers where n is 
printer specific
S  -  Permanent soft fonts
Mn  -  SIMMs where n is the number of the SIMM slot 
for example: M2 is SIMM in #2 slot.
NONE  -  Temporary soft fonts 
						

							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.
