| 63 |
printing, and a password for it to use when authenticating with the |
| 64 |
SMB printer server. |
| 65 |
|
| 66 |
Usage: lpr-client [options] [filename ... ] |
| 67 |
|
| 68 |
Examples of common usage: |
| 69 |
Set a password (must be done first): |
| 70 |
ssh-askpass | lpr-client --password |
| 71 |
Print a file: |
| 72 |
lpr-client foobar.ps |
| 73 |
Print a file on an alternative printer: |
| 74 |
lpr-client --printer=rby_3 foobar.ps |
| 75 |
Print a file on an alternative server and printer: |
| 76 |
lpr-client --service="//obelix/rby_4" foobar.ps |
| 77 |
Kill the agent (when logging out or when not printing anymore): |
| 78 |
lpr-client --kill |
| 79 |
|
| 80 |
Normal options: |
| 81 |
--print print files or stdin (default) |
| 82 |
--password set password, read from stdin |
| 83 |
--kill kill the agent |
| 84 |
|
| 85 |
--version show version number |
| 86 |
--help show this help |

|
| 88 |
--server=SERVER use a non-default printer server, |
| 89 |
this can also be specified with |
| 90 |
the environment variable |

LPR_CLIENT_SERVER |
| 92 |
-P, --printer=PRINTER use a non-default printer, |
| 93 |
this can also be specified with |
| 94 |
the environment variable |
| 95 |
LPR_CLIENT_PRINTER |
| 96 |
--service=SERVICE specify both server and printer |
| 97 |
on the form "//SERVER/PRINTER" |
| 98 |
--serverip=IP explicitly specify server IP |

"smbclient" |
| 101 |
|
| 102 |
Obscure or debugging options: |
| 103 |
--debug show debugging information |
| 104 |
--block-size=SIZE use blocks of the specified size |
| 105 |
--smbclientformat=FORMAT change the form of how |
| 106 |
"smbclient" is invoked with the |
| 107 |
specified parameters |
| 108 |
--smbclientcommand=COMMANDS change the command send to |
| 109 |
"smbclient" |
| 110 |
--write=FILE make the agent write the input |
| 111 |
to the specified file name |
| 112 |
--eval make the agent `eval' the input |
