This document discusses several aspects of printing with VectorLinux 5 using CUPS, the Common Unix Printing System. "CUPS" is a cross-platform printing solution for all UNIX environments. It is based on the "Internet Printing Protocol" and provides complete printing services to most PostScript and raster printers.
Check to see if your printer is supported at the following sites
If your printer accepts raw text you can test if your parallel port or usb port is working by sending some raw text to the printer. For example if the printer is connected to a parallel port enter:
date > /dev/lp0
If that does not work try /dev/lp1 or for usb it would be /dev/usb/lp0 or lp1 or which ever port you have it on. Note: my printer does not accept raw text, but because it automatically turns on when text is sent, it reacts to text being sent.
If you are going to use a printer on a Windows server you should check if the printer is available (see the section "Printing to Windows Servers via Samba").
If you are using the SOHO edition, CUPS was installed along with the system, so you can skip this chapter.
For other VL flavours, if you didn´t install CUPS when you installed VectorLinux (either because you decided no to install it or because it was not included in the installation iso/CD), you can do it now by launching VASM and selecting the appropiate package from the CD-Rom or from the online repository.
Be aware that the final step of the package´s installation can take several minutes to complete, depending on the system capabilities, so please be patient. As an example, this process can easily take around five minutes in a mid-level system.
If CUPS does not start at boot ensure that /etc/rc.d/init.d/cups is executable by root and that links to this exist in /etc/rc.d/rc2.d if you boot to console (text mode) and /etc/rc.d/rc5.d if you boot to a GUI.
When CUPS is installed, open your web browser of choice (not Dillo which does not support the passwords) and type:
Enter root as username and root´s password at prompt. Then select "Do Administration Tasks".
To add a printer, select "Add
Printer" and answer questions as required.

One way to print to a printer on a Windows Server is through the Microsoft Server Message Block ("SMB") protocol. Support for this protocol is provided with the free SAMBA software package. This is included in base install of VectorLinux v5
If you are going to use a printer on a Windows server ensure that you can access the server with the printer and determine share name via smbclient:
/usr/bin/smbclient -L server -U user
where server is name of the server and user is a login name on the server.
You should get something like:
interface ip=192.168.0.4 bcast=192.168.0.255 nmask=255.255.255.0
Before you proceed with the printer installation, check to see if there exists a symbolic link smb in the directory /usr/lib/cups/backend/. (If you installed CUPS using the preceding instructions the link should exist). If it is not there, you will need to create it by running the following command:
ln -s `which smbspool` /usr/lib/cups/backend/smb
The latter works for the default installation of all versions of VectorLinux 5. Alternatively, you can create this link using Midnight Commander.
Once you have made the link you can configure your printer as in section 3. When prompted for device, choose "Windows Printer via SAMBA" which is near the bottom of the list of devices. When prompted for device URI set the with:
The workgroup name need only be specified if your system is using a different workgroup. The user:pass strings are required when printing to Windows NT, 2K or XP servers or to shares with passwords enabled under Windows 95 and 98.
In these cases the entry could be simplified to one of:
NOTE: The user/pass must match an existent, active account on the server.

In this section we discuss how to set up VectorLinux to act as a print server for other printers on our network via SAMBA. It is assumed that you have your printer working locally using CUPS. We will need to make several changes to both CUPS and SAMBA configuration files.
Each of the Windows clients
must have the appropriate printer drivers.
If you are allowing anonymous access to your printer you will need to create a user account for remote print jobs. As root (or su) do the following:
useradd -d /home/smbprint -s -m /bin/false smbprint
This command adds a user called "smbprint" to your system. Make sure there is enough disk space in /home/smbprint, the "smbprint" user's home directory, to spool files. Since we have no password for the account "smbprint" we include "-s /bin/false" This causes an error if someone tries to access the system using this account. If you have configured CUPS to restrict printing to certain users on your system, you must allow the "smbprint" user to access printers you want to share.
The Samba configuration file is /etc/samba/smb.conf. The following is an example configuration file set up to use CUPS with the "smbprint" user:
The last line allows the Windows (and other SMB) clients to see the share when browsing.
Please note that this configuration will allow printing by anyone that can make a network connection to your computer and is not recommended for computers on untrusted networks, such as computers with direct Internet connections. If you need to implement access control, set security = user or security = domain and read the Samba man pages for further information. In addition you can refer to "The Unofficial Samba HOWTO" at http://hr.uoregon.edu/davidrl/samba/ for further pointers.
Once you have added the above settings to your Samba configuration file you must restart Samba with the command:
If SAMBA does not start at
boot, one method to do this is to create symbolic links, S44samba and
K55samba, to the above script in /etc/rc.d/rc2.d
if you boot to text mode and /etc/rc.d/rc5.d
if you boot to a GUI.
Windows printer drivers format their output for the printer before sending it across the network. You must configure CUPS to accept the pre-formatted output by uncommenting the following line from /etc/cups/mime.convs:
Also uncomment the following line from /etc/cups/mime.types:
Now CUPS must be told to allow connections from other machines on the network. Add these lines to /etc/cups/cupsd.conf:
As in the Samba configuration, this configuration allows any computer to connect to your printers and is not recommended for computers on untrusted networks. For example, if you want restrict printing to the subnet 192.168.0.* replace "Allow From All" with "Allow From 192.168.0.0/24".
For information about tightening access control to your printers, see the cupsd.conf man page and the CUPS documentation.
Finally, restart cups with the following command:
Your Linux printers should now be accessible to Windows PCs on the LAN. Follow the usual steps for adding a network printer to your Windows PCs, and remember to print a test page.
