hpoj reference: `ptal-devid`

The ptal-devid command-line utility displays the entire device ID string of a device, or specific fields if requested.

Syntax

The syntax of ptal-devid is as follows:

	ptal-devid [devname] [-previous] [[modifiers] queries]...

Where:

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

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.

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.
