Unix/Linux Printing

Printing Text Files form Unix

Text files on Unix systems contain lines that end with “newline” characters, as

opposed to MS-DOS and Windows-related operating systems that end with a

carriage return followed by a linefeed. Most printers require a carriage

return/linefeed pair at the end of each line, making it necessary for some

translation to be done before Unix text files can be printed on most printers.

For this purpose, you can define two “printers” for the same printer port, one that

prints to the port itself, and one that prints to the port name with

_TEXT

added to

the name. Files printed to the second port will be translated so that the printer has

the carriage return/linefeed pairs that it needs.

For example, you could define a printer

hp5l

that prints to port

PS-142634-P1

,

and a printer

hp5lt

that prints to port

PS-142634-P1_TEXT

.

Your graphics files

could then be printed to the

hp5l

printer, and “raw” text files could be printed to

the

hp5lt

printer.

Printing form BSD Unix Versions

For “flavors” of the Unix operating system derived from or related to the BSD

releases, such as SunOS 4.x, Linux, BSD/OS, FreeBSD, or NetBSD, you can use

the following procedure to enable users to print to a printer connected to your

D-LINK network print server:

1.

Log in as the superuser (root).

2.

Add an entry for the print server in the host’s

/etc/hosts

file, giving a hostname

for the print server’s IP address. A line in

/etc/hosts

contains an IP address

and one or more aliases for the host . For example:

202. 39. 74. 40

ps-142634

ps-142634.dlink.com.tw

If you use DNS (the Domain Naming Services protocol), you can add an address

record entry to your DNS database for the print server.

3.

Create a spool directory for the printer:

◊

On SunOS systems, create the directory as a subdirectory of

/var/spool

,

with the same name as the printer (e.g.,

/var/spool/hp5l

).

◊

On Linux systems, create the directory as a subdirectory of

/user/spool

/lp

.

◊

On BSD/OS, FreeBSD, or NetBSD systems, create the directory as

subdirectory of

/var/spool

.

4.

Change the owner and permissions of the directory so that it is owned and

writable by group

daemon

, using the following commands:

Page 108 / 150

104

chown

bin.daemon /var/spool/hp5l

chmod

775 /var/spool/hp5l

5.

Add an entry for the printer to

/etc/printcap

, similar to the following:

hp5l:\

:lp=:sd=/var/spool/hp5l :mx#0:\

:rm=ps-142634:rp=ps-142634-p1:

The meaning of each of the entries is described below. The directory path in the

sd

spool directory entry should match the directory name you created above. If

your entry requires more than one line you can escape the newline with a

backslash.

6.

Issue the command

lpc

start

hp5l

to start a spool daemon for the printer. The printer will now be available for use.

7.

Optionally, add another printcap entry (and issue another

lpc start

command)

for a second printer, using the

port_TEXT

port. This second printer name can be

used for printing text files.

Entries in

/ect/printcap

begin with a name for the printer or a list of name,

separated by | (a vertical bar). The entries used above are:

◆

lp=

The lp entry is used to specify a local printer device.

Since the printer is a remote printer, this entry should be blank.

Page 109 / 150

105

◆

sd=dir

The location of the printer’s local spool directory.

◆

mx#blocks

The limit for print job files in the local spool directory;

0 means no limit.

◆

rm=address

The host where the remote printer is located, in this case

the D-Link print server.

◆

rp=printer

The name of the printer on the remote host.

For the D-Link print server, the port name should be used.

Note: this entry is case-sensitive.

Printing from SCO Unix System V/386

To allow printing to a printer attached to your D-LINK network print server from a

SCO Unix System V/386 host.

1.

Login as the superuser (root).

2.

Add an entry for the print server in the host’s

/etc/hosts

file, giving a hostname

for the print server’s IP address. A line in

/etc/hosts

contains an IP address

and one or more aliases for the host. For example:

202.39.74.40

ps-142634

ps-142634.dlink.com.tw

If you use DNS (the Domain Naming Services protocol), you can add an address

record entry to your DNS database for the print server.

3.

Change to the

/dev

directory, and issue the command

mkdev rlp

4.

The script will ask:

Do you want to install or delet remote printing (i/d/q)?

Answer

i

and press Enter to continue.

5.

The script will ask:

Do you want to change the remote printer description file

/etc/printcap (y/n)?

Answer y and press Enter to continue.

6.

The script will ask:

Please enter the printer name (q to quit):

Enter an alias for the printer on the local machine and press Enter. This name

should be the same as the destination port name.
