Information about parallel and USB-connected printers is located in the /dev/printers directory.
To query printers for IEEE1284 device identification information, type:
# /usr/lib/lp/bin/printer-info -a /dev/printers/*
# /usr/lib/lp/bin/printer-info -a /dev/printers/* /dev/printers/0: Manufacturer: Hewlett-Packard Model: hp color LaserJet 4650 Description: Hewlett-Packard color LaserJet 4650 Class: PRINTER Command set: cmd: PJL cmd: MLC cmd: BIDI-ECP cmd: PCLXL cmd: PCL cmd: PDF cmd: PJL cmd: MIME cmd: POSTSCRIPT
Note that when you add a device with Solaris Print Manager, the same program is used to detect and provide information about the printer make and model in the Add Attached Printer dialog box. See printmgr(1M) for more information.
