Using a Disk File in a PCL Job The Alphanumeric ID command reads a file stored on the hard disk or floppy disk.

Using a Disk File in a PCL Job
The Alphanumeric ID command reads a file stored on the hard disk or
floppy disk. With this command, the D640 reads the file into memory
and treats this information as if it was part of the original print job. The
result is similar to an “include” statement in a high-level programming
language.
The D640 does not do any special processing of the file, see
“Recommended Contents of Binary Data” on page 46.
The format of the Alphanumeric ID command is as follows:
<ESC> & n # W [ file identification data ]
#
The number of bytes of data that follow the capital W. A value
must be supplied.
[file identification data]
Operation Byte (UB) – The Operation Byte is an unsigned byte, which
may have a value 0 through 5. The LaserJet family of printers uses
this byte to indicate whether the file contents are treated as a font or
as a macro. The D640 does not use this byte, but requires the value
to be within the range specified. (The values 0 to 5 are control codes
<SOH>
,
<STX>
,
<ETX>
,
<EOT>
, and
<ENQ>
.
)
File Identifier Name (ASCxx) – The File Identifier Name is ASCII data.
The D640 requires the full pathname of the file, including the volume
name. Files and directories can contain the letters A..Z, a..z, and the
numerals 0..9. For example:
C:\PCL5\USER\MyFile.pcl
.
Do not use
quotation marks around the filename.
The PCL commands to manage fonts, macros, patterns, and symbol
sets only act on objects in memory. The disk file can be removed only
with the @PJL FSDELETE command.
In the examples below, <LF> is a line feed, <CR> is carriage return,
<ESC> is the Escape character, and
→
means that the line is
continued.
