NAME

lp - print files  

SYNOPSIS

lp [ -E ] [ -U username ] [ -c ] [ -d destination[/instance] ] [ -h hostname[:port] ] [ -m ] [ -n num-copies ] [ -o option[=value] ] [ -q priority ] [ -s ] [ -t title ] [ -H handling ] [ -P page-list ] [ -- ] [ file(s) ]
lp [ -E ] [ -U username ] [ -c ] [ -h hostname[:port] ] [ -i job-id ] [ -n num-copies ] [ -o option[=value] ] [ -q priority ] [ -t title ] [ -H handling ] [ -P page-list ]  

DESCRIPTION

lp submits files for printing or alters a pending job. Use a filename of "-" to force printing from the standard input.  

THE DEFAULT DESTINATION

CUPS provides many ways to set the default destination. The LPDEST and PRINTER environment variables are consulted first. If neither are set, the current default set using the lpoptions(1) command is used, followed by the default set using the lpadmin(8) command.  

OPTIONS

The following options are recognized by lp:

--

Marks the end of options; use this to print a file whose name begins with a dash (-).

-E

Forces encryption when connecting to the server.

-U username

Specifies the username to use when connecting to the server.

-c

This option is provided for backwards-compatibility only. On systems that support it, this option forces the print file to be copied to the spool directory before printing. In CUPS, print files are always sent to the scheduler via IPP which has the same effect.

-d destination

Prints files to the named printer.

-h hostname[:port]

Chooses an alternate server.

-i job-id

Specifies an existing job to modify.

-m

Sends an email when the job is completed.

-n copies

Sets the number of copies to print.

-o "name=value [ ... name=value ]"

Sets one or more job options. See "COMMON JOB OPTIONS" below.

-q priority

Sets the job priority from 1 (lowest) to 100 (highest). The default priority is 50.

-s

Do not report the resulting job IDs (silent mode.)

-t "name"

Sets the job name.

-H hh:mm

-H hold

-H immediate

-H restart

-H resume

Specifies when the job should be printed. A value of immediate will print the file immediately, a value of hold will hold the job indefinitely, and a UTC time value (HH:MM) will hold the job until the specified UTC (not local) time. Use a value of resume with the -i option to resume a held job. Use a value of restart with the -i option to restart a completed job.

-P page-list

Specifies which pages to print in the document. The list can contain a list of numbers and ranges (#-#) separated by commas, e.g., "1,3-5,16". The page numbers refer to the output pages and not the document's original pages - options like "number-up" can affect the numbering of the pages.

 

COMMON JOB OPTIONS

Aside from the printer-specific options reported by the lpoptions(1) command, the following generic options are available:

-o collate=true

Prints collated copies.

-o fit-to-page

Scales the print file to fit on the page.

-o job-hold-until=when

Holds the job until the specified local time. "when" can be "indefinite" to hold the until released, "day-time" to print the job between 6am and 6pm local time, "night" to print the job between 6pm and 6am local time, "second-shift" to print the job between 4pm and 12am local time, "third-shift" to print the job between 12am and 8am local time, or "weekend" to print the job on Saturday or Sunday.

-o job-hold-until=hh:mm

Holds the job until the specified time in hours and minutes UTC.

-o job-priority=priority

Set the priority to a value from 1 (lowest) to 100 (highest), which influences when a job is scheduled for printing. The default priority is typically 50.

-o job-sheets=name

Prints a cover page (banner) with the document. The "name" can be "classified", "confidential", "secret", "standard", "topsecret", or "unclassified".

-o job-sheets=start-name,end-name

Prints cover pages (banners) with the document.

-o media=size

Sets the page size to size. Most printers support at least the size names "a4", "letter", and "legal".

-o mirror

Mirrors each page.

-o number-up={2|4|6|9|16}

Prints 2, 4, 6, 9, or 16 document (input) pages on each output page.

-o number-up-layout=layout

Specifies the layout of pages with the "number-up" option. The "layout" string can be "btlr", "btrl", "lrbt", "lrtb", "rlbt", "rltb", "tblr", or "tbrl" - the first two letters determine the column order while the second two letters determine the row order. "bt" is bottom-to-top, "lr" is left-to-right, "rl" is right-to-left, and "tb" is top-to-bottom.

-o orientation-requested=4

Prints the job in landscape (rotated 90 degrees counter-clockwise).

-o orientation-requested=5

Prints the job in landscape (rotated 90 degrees clockwise).

-o orientation-requested=6

Prints the job in reverse portrait (rotated 180 degrees).

-o outputorder=reverse

Prints pages in reverse order.

-o page-border=border

Prints a border around each document page. "border" is "double", "double-thick", "single", or "single-thick".

-o page-ranges=page-list

Specifies which pages to print in the document. The list can contain a list of numbers and ranges (#-#) separated by commas, e.g., "1,3-5,16". The page numbers refer to the output pages and not the document's original pages - options like "number-up" can affect the numbering of the pages.

-o sides=one-sided

Prints on one side of the paper.

-o sides=two-sided-long-edge

Prints on both sides of the paper for portrait output.

-o sides=two-sided-short-edge

Prints on both sides of the paper for landscape output.

 

CONFORMING TO

Unlike the System V printing system, CUPS allows printer names to contain any printable character except SPACE, TAB, "/", or "#". Also, printer and class names are not case-sensitive.

The -q option accepts a different range of values than the Solaris lp command, matching the IPP job priority values (1-100, 100 is highest priority) instead of the Solaris values (0-39, 0 is highest priority).  

EXAMPLES

Print two copies of a document to the default printer:

    lp -n 2 filename

Print a double-sided legal document to a printer called "foo":

    lp -d foo -o media=legal -o sides=two-sided-long-edge filename

Print a presentation document 2-up to a printer called "foo":

    lp -d foo -o number-up=2 filename

NAME

lp - line printer devices  

SYNOPSIS

#include <linux/lp.h>  

CONFIGURATION

lp[0-2] are character devices for the parallel line printers; they have major number 6 and minor number 0-2. The minor numbers correspond to the printer port base addresses 0x03bc, 0x0378 and 0x0278. Usually they have mode 220 and are owned by root and group lp. You can use printer ports either with polling or with interrupts. Interrupts are recommended when high traffic is expected, for example, for laser printers. For typical dot matrix printers, polling will usually be enough. The default is polling.  

DESCRIPTION

The following ioctl(2) calls are supported:

int ioctl(int fd, LPTIME, int arg)

Sets the amount of time that the driver sleeps before rechecking the printer when the printer's buffer appears to be filled to arg. If you have a fast printer, decrease this number; if you have a slow printer, then increase it. This is in hundredths of a second, the default 2 being 0.02 seconds. It influences only the polling driver.

int ioctl(int fd, LPCHAR, int arg)

Sets the maximum number of busy-wait iterations which the polling driver does while waiting for the printer to get ready for receiving a character to arg. If printing is too slow, increase this number; if the system gets too slow, decrease this number. The default is 1000. It influences only the polling driver.

int ioctl(int fd, LPABORT, int arg)

If arg is 0, the printer driver will retry on errors, otherwise it will abort. The default is 0.

int ioctl(int fd, LPABORTOPEN, int arg)

If arg is 0, open(2) will be aborted on error, otherwise error will be ignored. The default is to ignore it.

int ioctl(int fd, LPCAREFUL, int arg)

If arg is 0, then the out-of-paper, offline, and error signals are required to be false on all writes, otherwise they are ignored. The default is to ignore them.

int ioctl(int fd, LPWAIT, int arg)

Sets the number of busy waiting iterations to wait before strobing the printer to accept a just-written character, and the number of iterations to wait before turning the strobe off again, to arg. The specification says this time should be 0.5 microseconds, but experience has shown the delay caused by the code is already enough. For that reason, the default value is 0. This is used for both the polling and the interrupt driver.

int ioctl(int fd, LPSETIRQ, int arg)

This ioctl(2) requires superuser privileges. It takes an int containing the new IRQ as argument. As a side effect, the printer will be reset. When arg is 0, the polling driver will be used, which is also default.

int ioctl(int fd, LPGETIRQ, int *arg)

Stores the currently used IRQ in arg.

int ioctl(int fd, LPGETSTATUS, int *arg)

Stores the value of the status port in arg. The bits have the following meaning:

LP_PBUSY	inverted busy input, active high
LP_PACK	unchanged acknowledge input, active low
LP_POUTPA	unchanged out-of-paper input, active high
LP_PSELECD	unchanged selected input, active high
LP_PERRORP	unchanged error input, active low

Refer to your printer manual for the meaning of the signals. Note that undocumented bits may also be set, depending on your printer.

int ioctl(int fd, LPRESET)

Resets the printer. No argument is used.
