HomeSYNOPSIS
status [, flags] = handle:lpstatus()
DESCRIPTION
Reports the status of a printer device.
The returned status value contains the printer status in a format compatible with the status register of a standard PC parallel port. The following bits are contained in the status:
| 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
|---|---|---|---|---|---|---|---|
| Reserved | Paper Empty | Select | Not Error | Reserved | |||
Some printers have a vendor specific status word. When supported by the driver, this is returned as a second value. The format of the status word depends on the printer model. Check with rawio:usbInfo() which printer model is attached before using this data.
RETURN VALUE
On success, returns a status and possibly a flags value. On error, returns nil. In case of
an error, the error can be retrieved using rawio:lastError().
