The CUPS (Common Unix Printing System) software manages printers connected to the local computer or over a network. The local printers are attached via a loop-back connection (IP 127.0.0.1), a network connection pointing to the same system.

Install CUPS and add the user(s) to the lp group to gain permissions to access the devices. This can be done as root in a terminal:

# tazpkg get-install cups
# addgroup tux lp

Again as root, customise the default configuration in /etc/cupsd.conf:

# Administrator user group...
SystemGroup lp

# Restrict access to the admin pages...

  Order allow,deny
  Allow 127.0.0.1


# Restrict access to configuration files...

  AuthType Default
  Require user @SYSTEM
  Order allow,deny
  Deny From None
  Allow From 127.0.0.1

Set the administrative password for CUPS and add an administrative user:

# lppasswd -g lp -a tux

You should now be able to have access to the CUPS administration through your browser by entering the address http://localhost:631/// Install the printer drivers with the following packages: - hplip : for HP printers - gutenprint : for Canon, Epson, Lexmark, Sony, Olympus - foomatic-db, foomatic-db-engine, foomatic-db-nonfree and foomatic-filters : several free software printer drivers - ufr2: for Canon printers (extra drivers) - splix: for Samsung - cups-pdf: for “printing” to PDF files For example, install the HP printer drivers with the following root command <code> # tazpkg get-install hplip </code> Now you add a new printer in the browser interface and choose: LPD/LPR Host or Printer (Unknown), and add the address socket//192.168.2.1:9100 If you get the error, “Returning IPP client-error-document-format-not-supported for Print-Job in /var/log/cups/error.log” then add two files to the /etc/cups directory. The easiest method is to start a text editor such as Leafpad from a root terminal; start the Terminal and switch to the root user. * mime.convs (/etc/cups/mime.convs): <file> application/pdf application/postscript 33 pdftops application/postscript application/vnd.cups-postscript 66 pstops application/vnd.hp-HPGL application/postscript 66 hpgltops application/x-cshell application/postscript 33 texttops application/x-csource application/postscript 33 texttops application/x-perl application/postscript 33 texttops application/x-shell application/postscript 33 texttops text/plain application/postscript 33 texttops text/html application/postscript 33 texttops image/gif application/vnd.cups-postscript 66 imagetops image/png application/vnd.cups-postscript 66 imagetops image/jpeg application/vnd.cups-postscript 66 imagetops image/tiff application/vnd.cups-postscript 66 imagetops image/x-bitmap application/vnd.cups-postscript 66 imagetops image/x-photocd application/vnd.cups-postscript 66 imagetops image/x-portable-anymap application/vnd.cups-postscript 66 imagetops image/x-portable-bitmap application/vnd.cups-postscript 66 imagetops image/x-portable-graymap application/vnd.cups-postscript 66 imagetops image/x-portable-pixmap application/vnd.cups-postscript 66 imagetops image/x-sgi-rgb application/vnd.cups-postscript 66 imagetops image/x-xbitmap application/vnd.cups-postscript 66 imagetops image/x-xpixmap application/vnd.cups-postscript 66 imagetops image/x-sun-raster application/vnd.cups-postscript 66 imagetops image/gif application/vnd.cups-raster 100 imagetoraster image/png application/vnd.cups-raster 100 imagetoraster image/jpeg application/vnd.cups-raster 100 imagetoraster image/tiff application/vnd.cups-raster 100 imagetoraster image/x-bitmap application/vnd.cups-raster 100 imagetoraster image/x-photocd application/vnd.cups-raster 100 imagetoraster image/x-portable-anymap application/vnd.cups-raster 100 imagetoraster image/x-portable-bitmap application/vnd.cups-raster 100 imagetoraster image/x-portable-graymap application/vnd.cups-raster 100 imagetoraster image/x-portable-pixmap application/vnd.cups-raster 100 imagetoraster image/x-sgi-rgb application/vnd.cups-raster 100 imagetoraster image/x-xbitmap application/vnd.cups-raster 100 imagetoraster image/x-xpixmap application/vnd.cups-raster 100 imagetoraster image/x-sun-raster application/vnd.cups-raster 100 imagetoraster application/vnd.cups-postscript application/vnd.cups-raster 100 pstoraster </file> * mime.types (/etc/cups/mime.types): <file> application/pdf pdf string(0,%PDF) application/postscript ai eps ps string(0,%!) string(0,<04>%!) \ contains(0,128,<1B>%-12345X) + \ (contains(0,4096,“LANGUAGE=POSTSCRIPT”) \ contains(0,4096,“LANGUAGE = Postscript”) \ contains(0,4096,“LANGUAGE = PostScript”) \ contains(0,4096,“LANGUAGE = POSTSCRIPT”) \ (contains(0,4096,<0a>%!) + \ !contains(0,4096,“ENTER LANGUAGE”))) application/vnd.hp-HPGL hpgl \ string(0,<1B>E<1B>%0B) \ string(0,<1B>%-1B) string(0,<201B>)\ string(0,BP;) string(0,IN;) string(0,DF;) \ string(0,BPINPS;) \ (contains(0,128,<1B>%-12345X) + \ (contains(0,4096,“LANGUAGE=HPGL”) \ contains(0,4096,“LANGUAGE = HPGL”))) ######################################################################## # # Image files… # image/gif gif string(0,GIF87a) string(0,GIF89a) image/png png string(0,<89>PNG) image/jpeg jpeg jpg jpe string(0,) &&\ (char(3,0xe0) char(3,0xe1) char(3,0xe2) char(3,0xe3)\ char(3,0xe4) char(3,0xe5) char(3,0xe6) char(3,0xe7)\ char(3,0xe8) char(3,0xe9) char(3,0xea) char(3,0xeb)\ char(3,0xec) char(3,0xed) char(3,0xee) char(3,0xef)) image/tiff tiff tif string(0,MM<002A>) string(0,II<2A00>) image/x-photocd pcd string(2048,PCD_IPI) image/x-portable-anymap pnm image/x-portable-bitmap pbm string(0,P1) string(0,P4) image/x-portable-graymap pgm string(0,P2) string(0,P5) image/x-portable-pixmap ppm string(0,P3) string(0,P6) image/x-sgi-rgb rgb sgi bw icon short(0,474) image/x-xbitmap xbm image/x-xpixmap xpm ascii(0,1024) + string(3,“XPM”) #image/x-xwindowdump xwd string(4,<00000007>) image/x-sun-raster ras string(0,<59a66a95>) #image/fpx fpx image/x-alias pix short(8,8) short(8,24) image/x-bitmap bmp string(0,BM) && !printable(2,14) image/x-icon ico ######################################################################## # # Text files… # application/x-cshell csh printable(0,1024) + string(0,#!) +\ (contains(2,80,/csh) contains(2,80,/tcsh)) application/x-perl pl printable(0,1024) + string(0,#!) +\ contains(2,80,/perl) application/x-shell sh printable(0,1024) + string(0,#!) +\ (contains(2,80,/bash) contains(2,80,/ksh)\ contains(2,80,/sh) contains(2,80,/zsh)) application/x-csource c cxx cpp cc C h hpp \ printable(0,1024) + \ (string(0,/*) string(0,)

application/octet-stream </file>

1. With the printer plugged in and powered on, run

   # su root
   # tazpkg recharge
   # tazhw setup printer

2. Install only hplip and hal-cups-utils
3. The printer should show up in the list of printers displayed as part of this command. It will then attempt to open the CUPS admin pages in Midori (at http://localhost:631 )
4. On my system, the printer does not show up in the browser under 'Find printers' and I get a 'Forbidden' error when trying to add a printer via the browser
5. Instead, run

   # hp-setup

   and follow the instructions. The test page should print correctly. The printer should also show up in the list of printers in applications (like the text editor) and will also appear in the list of printers on the CUPS browser pages, although in my case it is still not possible to make any changes to it

Power on the scanner before installing the following packages:

• xsane
• sane-backends
• libusb
• libusb-compat
• usbtools
• usbutils

for PKG in xsane sane-backends-libusb libusb-compat usbtools usbutils; do 
tazpkg get-install $PKG
done

With those packages installed, use the Hardware Detection Tool (Menu > System Tools > Hardware Detection And Drivers) Click on Scanner button

If your scanner does not show up immediately, enter for none in my set-up; now the scanner device should be listed in purple text, e.g.:

/dev/bus/usb/004/002

Your scanner must be in scanner group with 666 permissions

$ crw-rw-rw-    1 root     scanner  189, 385 Jun 22 19:44 /dev/bus/usb/0 

Reply y to start scanner Warning pops up about running scanner as root Click continue at your own risk button Agree to license

Xsane should open and be working!

The tux user is automatically added to scanner group, so tux may scan, but if you run under another user name that user can't scan until you add them to scanner group. Do this with the command (as root):

# addgroup //username// scanner
