Status and Error Messages
Printers return PostScript emulation error messages and status information to the
computer through any active interface. To send information to the computer through
the parallel interface, configure the interface as bidirectional.
Tagged Binary Not Active
Your printer responds and processes a Ctrl-T (x'14') command as a status query
when:
• The PostScript emulation interpreter is processing a print job.
• The printer is idle and the PostScript emulation interpreter is the selected
interpreter.
Mounted boolean True System attempts to mount the ROM.
False System attempts to dismount the ROM.
When a device is mounted, it becomes known to the system and is
readable, depending on the nature of the device.
A device must contain a valid file system or it will not mount successfully. To
verify if the device is currently mounted, query this parameter immediately
after setting it.
If the ROM device is dismounted, unpredictable results occur.
PhysicalSize integer (Read-only) Indicates the size of the ROM (in pages) that is mounted. A
value of 0 (zero) indicates that the device is not mounted. This parameter is
only valid when ROM is mounted.
Removable boolean (Read-only) Always False.
Searchable boolean (Read-only) Indicates if ROM participates in searches in file system
operations that specify a filename without specifying a device.
SearchOrder integer (Read-only) If the Searchable parameter is True, indicates the priority
assigned to the ROM when searching for a file and no device has been
specified. A lower integer indicates a higher priority. If the Searchable
parameter is False, the value of this integer has no meaning.
Type name (Read-only) Always returns the value of /FileSystem.
Writeable boolean (Read-only) Indicates if the files on the ROM can be opened for write
access. Always False.
