Lpr error no default destination

Forum Community Help: Check the Help Files, then come here to ask! Technical lpr: error — no default destination available. lpr: error — no default destination available. I’m setting up (or trying to), CUPs and SAMBA. Samba is installed and working, and most of CUPs is installed and working. My problem is I want setup printer sharing, so I need CUPs to play along with SAMBA. Well when I try to run any lpr / lp command I get the error no default destination available… linuxserver1:~ # cat /etc/hosts | lpr lpr: error — no default destination available. The printer is installed and working. I have printed a test page, so I’m more than sure it works. linuxserver1:~ # lpstat -v device for Epson600: parallel:/dev/lp0 But I still can’t for some reason figure out how to setup a ‘default destination.’ I don’t even know what destination it wants! Does it need the destination of the printer: i.e: /dev/lp0. Does it need the destination of the spool directory?.. i.e: /var/spool/. I have tried doing lpadmin -d [Epson600], but it has not helped.. So any help you guys can provide would be loved. cheers Ok I got SAMBA and CUPS working together. My only problem now is when ever lpr is called I get an error message «no default destination availibal». Im guessing this is the default destination of the printer… How would I go about configuring this? I’ve checked CUPS website (localhost:601 I believe), and I have no option to set the printer as default. =. So any help would be loved… Also can anyone explain lp and lrp… They seem to be differnt protocols, because from lp I can print locally, but not from lrp… =. I’m so lost and confoozed. I believe you need to define a print queue.

It works fine from Firefox, Acrobat Reader etc. but it doesn’t work from command line. I get the following message: Code:   $ lpr lpr: Error — no default destination available. $ lpstat -hlocalhost -p -d printer EPSON_LP-8700PS3_133.5.123.11 is idle.  enabled since Tue 27 Mar 2007 12:39:52 PM JST no system default destination How to set «default destination» ? My /etc/printcap is as follows: Code: # This file was automatically generated by cupsd(8) from the # /etc/cups/printers.conf file.  All changes to this file # will be lost.

108.4 Managing Printers and Printing[edit | edit source]

Candidates should be able to manage printer queues and user print jobs using CUPS and the LPD compatibility interface

Key Knowledge Areas

• Basic CUPS configuration (for local and remote printers).
• Manage user print queues.
• Troubleshoot general printing problems.
• Add and remove jobs from configured printer queues.

Introducing CUPS[edit | edit source]

CUPS (Common Unix Print System) is the standard print system on Linux. The cups server is cupsd; it listens on port 631 and accepts print jobs using IPP (the Internet Printing Protocol). IPP is layered over HTTP, in the sense that an IPP request is an HTTP request with a specific type of content.

Illustration 108.4-1: CUPS Printing System

The CUPS server handles printer queue management and also provides a web server (also on port 631) that supports a browser-based configuration interface allowing the addition and deletion of printers, printer queue management, and so on.

Figure 108.4-2: CUPS Web Interface: Home Page

CUPS filters

The internal work-flow within cups can be relatively complex:

Figure 108.4-3: Linux Printing Architecture

The front-end of CUPS is the actual server that handles the queuing of print jobs and provides the web-based configuration interface. Beyond that, at the heart of the work-flow are the filters, which provide format conversion from the initial input file (plain text, jpeg image, etc) to the language understood by the actual printer. These filters are based on Ghostscript (a GNU project). They consult PPD (Postscript Printer Description) files which specify the printer’s capabilities. The filters are found in (for example) /usr/share/ghostscript.

Ghostscript can also be invoked from the command line with the name gs. This command takes postscript or PDF files as input and generates an output file for a specific printer type. It has a database of printer drivers it can handle (this list is reasonably up to date, for example many USB printers are supported) and converts the postscript directly into PCL for these known models. Run the command gs -h to see a list of supported devices:

CUPS back-ends

CUPS supports a variety of back-ends. The term back-end refers to the technology or protocol used to connect to the printer. The table below gives some examples:

Table: CUPS Back-end Technologies

Back-end	URI Syntax	Example
Parallel port	parallel:/dev/lpx	parallel:/dev/lp0
USB	usb://make/model?serial=number	usb://hp/officejet123?serial=108442
ipp	ipp://host/printers/queue	ipp://neptune/printers/xerox1
LPD	lpd://host/queue	lpd://neptune/xerox1
socket	socket://host:port	socket://neptune:9100
CIFS	smb://user:password@workgroup/host/share

CUPS printers can be added using the web-based interface. The figure below shows two of several screens in this sequence:

Figure 108.4-4: Adding a Printer — I

Figure 108.4-5: Adding a Printer — II

Printers can also be assigned to classes. This is mainly useful on heavy duty print servers that have several printers of the same type connected. Users send print jobs to a class; CUPS will print them on the first printer that becomes available.

Legacy commands for printing[edit | edit source]

CUPS replaces two earlier printing systems used in UNIX and Linux. One comes from System V Unix, and the other comes from BSD (Berkeley Software Distribution). These two systems were principally intended for printing of plain text files from the command line (and not, for example, printing of office documents with embedded images from a graphical application such as Open Office). The two systems, whilst conceptually similar, used different commands, different configuration files, and a different protocol to talk to the print server.

For backward compatibility, CUPS provides «work-alike» versions of many of these command-line tools. These include:

Command	Description
lp, lpr	submit files for printing
lpq	print printer queue status
lprm	remove a queued print job
accept	Allow jobs to be sent to a print queue
reject	Prevent jobs from being sent to a print queue
cupsenable	Allow jobs to be sent from a queue to a printer
cupsdisable	Stop jobs being sent from the queue to the printer
lpstat	Show the status of the CUPS printer queues
lpadmin	Configure cups printers and classes

When using CUPS, these command submit jobs to the CUPS server which performs its usual filtering and back-end processing.

lp and lpr

The lpr and lp utilities are used to submit jobs to a printer. Note that they use different command options. For example lpr uses the -P flag to specify the printer, lp uses the -d flag.

lpq

A user can monitor the status of print queues with lpq. In the example below, demo-1 is the name of the printer.

lprm

The lprm command is used to delete jobs from the print queue. In the example below we delete job 4 from the demo-1 print queue then redisplay the queue:

lpstat

lpstat displays status information about the current classes, jobs, and printers. When run with no arguments, lpstat will list jobs queued by the current user.

Example:

cupsenable and cupsdisable

These commands are used to enable and disable specified printer queues. cupsdisable stops jobs being taken from the queue and sent to the printer. It does not prevent new jobs being sent to the queue. cupsenable re-starts the servicing of the queue.

accept and reject

These commands are used to enable and disable the filling of specified printer queues. In the example below we use reject to disable the demo-1 queue, then attempt to print a file to it. We then re-enable the printer, and successfully send a job to the queue:

lpadmin

The lpadmin command performs a variety of administrative operations on CUPS printers. For example it can be used to set the default printer. In the command sequence shown below there is initially do default destination set. After running lpadmin, we can print to the default printer by using lpr without specifying a printer name:

lpadmin can also be used to delete CUPS printers. In the example below we first list the available queues, then use lpadmin to remove one of them, then list the queues again:

The following is a partial list of the used files, terms and utilities:

• CUPS configuration files, tools and utilities
• /etc/cups
• lpd legacy interface (lpr, lprm, lpq)
