ptal-devid(8)
NAME
hpoj reference: "ptal-devid"
SYNOPSIS
ptal-devid [devname] [-previous] [[modifiers] queries]...
DESCRIPTION
The "ptal-devid" command-line utility displays the entire device ID
string of a device, or specific fields if requested.
OPTIONS
· "devname" is the optional PTAL device name
- · "modifiers" affect subsequent "queries" and may be one of:
- · "-previous" -- Retrieves previous device ID string if possible
- · "-short" -- Displays field values only
- · "-long" -- Displays leading field name through semicolon
(default)
- · "queries" request specific fields to be displayed instead of the
- entire string, and may be zero or more of:
- · "-field fieldname" -- Queries specific field
- · "-mfg" -- Queries manufacturer fields
- · "-mdl" -- Queries model fields
- · "-cmd" -- Queries command-set fields
- · "-sern" -- Queries serial-number fields
EXAMPLES
All of the following examples are for a USB-connected HP OfficeJet G85.
In the first example, line breaks were added between fields in this
document for clarity. Normally, the entire device ID string is printed
as one line, and it should line-wrap on your display.

NOTES
- If no modifier or "query" switches are specified, then by default the
entire device ID string is displayed. Otherwise, only the requested
field(s) are queried. Blank lines are displayed in the place of
requested fields that aren't present. The "-short" and "-long"
modifiers must be specified before the query options you want them to affect. The "-previous" switch is useful for determining what model is attached in cases where "ptal-mlcd" is unable to establish
communication with the device. It has no effect on JetDirect-connected devices. If you specify "-previous", then it must come after the device name (if specified) and before all other options. Currently, both "ptal-mlcd" and JetDirect cache the device ID string, and the
device ID string is not re-read from the device each time you invoke "ptal-devid". To get a fresh copy of the device ID string, you must
either power-cycle or disconnect/reconnect the device, both of which
interrupt the communication session with the device. However,
disconnecting/reconnecting the network cable will not help.
