Provides printer backend support for Xstation attached printers.
piolpx PseudoDevice [ BackendFlags ] PrintFile ...
The piolpx command accepts the name of files to be printed and printer backend flags and their arguments, reads the pseudo device file to determine the communication characteristics, and then invokes the printer backend piobe command. The output from the piolpx command is piped to the catlpx program.
The command builds flags for the catlpx program in the following communications characteristics format:
catlpx XStationName /* For parallel */
catlpx XStationName -s[0-4]Baud,Parity,Bits,Stops
/* For serial */
Finally, the piolpx command passes print file names and backend flags, if any are specified, to the backend in the following format:
piobe [BackendFlags] PrintFile ... | catlpx ...
| BackendFlags | Specifies the backend flags listed in the qprt command. The piolpx command supports all the qprt command backend flags. |
| bpc | Designates the bits per character for the pseudo device. |
| parity | Indicates parity within the pseudo device with the following values:
|
| port | Designates the port. Values for the port number are p for parallel, s for a single serial port, or s[0-4] when there is more than one serial port. |
| PrintFile | Indicates the name of the file or files to be printed to the virtual printer. |
| PseudoDevice | Indicates the pseudo device file to be read. The piolpx command reads the pseudo device file to determine the communication characteristics of the device as follows: |
| speed | Designates the baud rate in the pseudo device. |
| stops | Designates the number of stop bits in the pseudo device. |
To print the NewFile file with a pitch value of 12 to the Xstation named Einstein with a printer attached to the parallel port, enter
/usr/lib/lpd/pio/etc/piolpx p@Einstein -o -p -o 12 NewFile
