Copying and scanning
Copiers (
copy*
) allow scanning and copying by logging in with a numeric code. To copy, you must obtain a six-digit code, which you can apply for at
tajemniceuzhbAP05S@fi9a=MpCdRq.muniGv=UhUpFf.cz
. The code (and with it the right to copy) is (from August 2021) allocated with validity for all copiers.
The general code 0 can also be used for scanning and then the result can be sent to the address you specify. And see also the scanners in the PC hall.
Printing from Windows
You can print in two ways:
- printer sharing via Samba - printing can also be done on WiFi
- CUPS print server - need to have the same login as the faculty on the PC, only when connected by Ethernet cable
Sharing printers via Samba
Download the installer from the printer list, "Samba" column. Running it will add a new printer and install the appropriate drivers.
You can also print to this installed printer from Eduroam or wlan_fi WiFi networks.
If printing does not work from Windows 11, it should help to run
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Printers\RPC" /v RpcUseNamedPipeProtocol /t REG_DWORD /d 1 /f
in the command prompt with administrator privileges (this is a bug that we expect to be resolved in a future OS patch, so the installation packages have not been updated yet).
CUPS print server
- The machine you are printing from must have the same login as your faculty login.
- The machine must be connected to the network with an Ethernet cable and be allowed to print from it. If you wish to allow printing from your machine, email
unix55Ty6HMog@fikankt0Owg.munih_lTL7YnJ.cz
. - Download the installer from the printer list, column "CUPS". Running it will add a new printer and install the appropriate drivers.
Note: Do not confuse the login with the so-called display name, which is displayed e.g. in the menu of
Start
. You can leave this unchanged.
To change the login name (login), follow these steps + restart the PC:
-
Tento Počítač | My Computer | This PC → spravovat | manage → Lokální uživatelé a skupiny | Local Users and Groups → Uživatelé | Users →
Via the GUI.Přejmenovat | Rename
- Through the command prompt with admin rights:
wmic useraccount where name='AktuálníLogin' rename NovýLogin
Manually add a printer
When installing, you need to install the printer drivers yourself, depending on the specific printer type, see the Printer List section.
Start → Devices and Printers → Add a Printer → Add a network, wireless or Bluetooth printer
→ The printer that I want isn't listed → Select a shared printer by name
(location and naming may vary slightly in different versions of Windows). And in the printer name field, type
http://print.fi.muni.cz:631/printers/
and the printer name, e.g.
lj4b
or
lj5c
. The resulting string might look like this, for example:
http://print.fi.muni.cz:631/printers/lj3b
.
Printing from macOS
There are two ways to print:
- printing via Samba - you can also print over WiFi
- using IPP (Internet Printing Protocol) - need to have the same login as the faculty on the PC, only when connected by Ethernet cable
Printing via Samba
- Disconnect the system from the network, both wired (Ethernet) and wireless (WiFi).
- System Settings → Printers and Scanners → Add Printer, Scanner or Fax → Advanced (must click between the icons on the toolbar when the Control key is pressed - for example between the options
IP
andWindows
, selectupravit panel nástrojů
and dragPokročilé
there ) - The printer settings are as follows:
- Type:
Windows printer via spoolss
- device:
jiné zařízení
- URL:
smb://print.fi.muni.cz/lj3b?encryption=no
(lj3b
adjust according to the printer where you want to print) - Name and Location fill in separately
- Download the appropriate driver according to the printer hardware, or try selecting
Generic Postscript Printer
, this should also usually work.
- Type:
- Then just add the printer. If you want to print duplex, you need to select
Duplex Printing Unit
after entering and confirming this information. See also the section Non-functioning print options on copiers. - You can now reconnect to the network.
- The first time you print, an authentication dialog should pop up, where you need to enter the faculty login and faculty password. These can be saved to a keychain, then authentication will no longer be required each time you print.
Non-functional print options on copiers
Printing via Samba from macOS and Linux can ignore print settings, including duplex settings. If you encounter this problem, you can use the special queue
copy4b-duplex
(other copiers do not have such a queue accessible via Samba), or print from Anxur via
lp
or
lpr
, or email us at
unixKCUAgC3hl@fiO2zNeet7X.muninbnIpyBtJ.cz
.
Printing using IPP (Internet Printing Protocol)
- The machine you print from must have the same login as your faculty login.
- The machine must be connected to the network with an Ethernet cable and be allowed to print from it. If you wish to allow printing from your machine, email
unix_ptDfxY6f@fi4daBb_Hza.muniQyA8BoXFS.cz
.
You can add a new printer via
Nastavení systému → Tiskárny a skenery → Přidat tiskárnu, skener nebo fax
. You then need to fill in the configuration in the IP tab, for example for lj3b-duplex:
- Address: print.fi.muni.cz
- Protocol.
- Queue: printers/lj3b-duplex
- Name: Print lj3b duplex
- Use: Generic PostScript Printer
If this is a duplex queue, you must select
Duplex Printing Unit
after entering and confirming this information.
Printing from Linux
You can print in the following ways:
- using pure IPP (Internet Printing Protocol) - need to have the same login on the PC as the faculty, only when connected by Ethernet cable.
-
IPP + Kerberos - need to set up Kerberos and use
kinit
; can also print on WiFi - printing via Samba - can also print on WiFi
Printing using IPP (Internet Printing Protocol)
- The machine you print from must have the same login as your faculty login.
- The machine must be connected to the network with an Ethernet cable and be allowed to print from it. If you wish to allow printing from your machine, email
unixqhYOENWjr@fiQrEymlD_w.muningQbTtUNS.cz
.
It is essential to have the
CUPS printing system installed. Once CUPS is installed, you need to add (or edit the existing) entry
ServerName
to the
/etc/cups/client.conf
file on a separate line:
ServerName print.fi.muni.cz
Print jobs must be sent from a user account whose login is the same as your faculty login. Therefore, we generally recommend working under an account with a faculty login.
Alternatively, in other cases, printing can be done by creating an auxiliary account with a faculty login and then running the programs to be printed from from the command line, either via
gksudo
:
mujlogin$ gksudo -u xlogin libreoffice &
or, if you have an SSH server installed and running on your machine, using
ssh
:
mujlogin$ ssh -CY xlogin@localhost
xlogin$ libreoffice &
Printing with IPP + Kerberos
With Kerberos authentication, you do not need to have the same login on the machine as the faculty login.
It is essential to have the
CUPS printing system installed. Once CUPS is installed, you need to add (or edit the existing) entry
ServerName
to the
/etc/cups/client.conf
file on a separate line:
ServerName print.fi.muni.cz
If you have previously used printing using pure IPP, you must unenable printing from your machine or Kerberos will not try to use it at all. Send the request to
unixK1eiSp0x0@fiYL537Mmlj.munilO11mHln3.cz
.
Next, set up Kerberos. Install basic support, on Ubuntu:
# apt install krb5-user
or on Fedora/CentOS:
# yum install krb5-workstation
and configure the faculty domain (or realm):
$ cat /etc/krb5.conf
[libdefaults]
default_realm = FI.MUNI.CZ
…
[realms]
…
FI.MUNI.CZ = {
kdc = krb.fi.muni.cz
kdc = krb1.fi.muni.cz
default_domain = fi.muni.cz
}
…
[domain_realm]
…
.fi.muni.cz = FI.MUNI.CZ
fi.muni.cz = FI.MUNI.CZ
Before accessing the print system, you must obtain a Kerberos ticket at the command line by typing
kinit
. You authenticate with your faculty login (in our example,
xlogin
) and faculty password:
$ kinit xlogin
Password for xlogin@FI.MUNI.CZ:
A ticket obtained in this way will last for about 24 hours, then you must re-authenticate.
By now, printing should work from both graphical applications and the command line.
Printing with Samba
For this procedure, you do not need to have printing enabled from the machine, nor do you need to have a login on the machine that matches the faculty login.
However, the disadvantage of this procedure (especially with respect to printing from Linux via
Kerbero) is that the faculty login credentials are stored on disk unencrypted, although they are only readable by the user
root
.
You may also run into problems with printing options on copiers.
You must also install printers, or print queues, individually, and we do not support this method of printing for multiple printers.
See the FI printers over Samba on Linux repository for installation instructions.
Printing from the command line
Basic commands:
- Print:
lpr -Pqueue_name file1 file2 ...
- List the contents of the print queue:
lpq -Pqueue_name
- Cancel print job:
lprm -Pqueue_name job_id
Example:
anxur$ lpr -Plj2b file.pdf
anxur$ lpq -Plj2b
lj2b is ready and printing
Rank Owner Job File(s) Total Size
active xlogin 224 file.pdf 1024 bytes
anxur$ lprm -Plj2b 224
Details about
lpr
(individual parameters of
lpr
can usually be entered at once in a single command):
- Enforce paper format (see also tips below):
lpr -o media=a5 file
- Force duplex printing (rotate over the longer side of the sheet):
lpr -o sides=two-sided-long-edge file
- Force duplex printing (rotate over the shorter side of the sheet):
lpr -o sides=two-sided-short-edge file
- Multiple (reduced) document pages per page:
lpr -o number-up=4 file
- Printing in triplicate:
lpr -#3 file
- ... for a full list of generally applicable options, click here
Printers also provide model-specific parameters. A list of these can be found using the following command:
$ lpoptions -p copy2b -l
OptionName/Option Description: *Default AnotherValue YetAnotherOne
and then use:
lpr -o LPOptionName=AnotherValue file.pdf
Tips for printing from Linux
Printing from Aisa or Anxur
If printing does not work (because your Kerberos ticket has expired, or you logged in with a key and not a password), you need to enter the command
kinit
and enter your password.
Printing with automatic copy scrolling
On Triumph-Adler 4505ci or 5007ci copiers (all except copy2c), single copy offset (also offset or jog) can be enabled. This can be particularly useful when printing multi-page assignments.
Parameters
lpr
for TA 4505ci:
-# 2 # number of copies
-o Jog=True # enable offset
-o KCCollate1=On # prerequisite for jogging
For setting up the TA 4505ci in the graphical interface:
- Set the number of copies.
- Turn off General → Collate
- Turn on Finishing → Offset
- Set Advanced → Job Settings to Collate
For TA 5007ci:
-# 2 # number of copies
-o Sep=Jog # enable offset
TA 5007ci in the GUI:
- Set the number of copies
- Turn off Collate.
- Set Advanced → Finishing → Separation to Offset Jobs
- Turn Advanced → General → Collate on.
Automatically staple sheets when printing
The corresponding parameter
lpr
is for Triumph-Adler 4505ci
-o KCStaple=Upperleft # lowercase l
-o KCStaple=UpperRight # actually results in LowerLeft
-o KCStaple=Center
and for Triumph-Adler 5007ci
-o Stpl=Rear # means UpperLeft
-o Stpl=Front # actually results in LowerLeft
-o Stpl=Center
If you print multiple copies using the
-#n
parameter, you also need to add the
-o Collate=true
parameter.
Default printer settings
To avoid having to constantly enter the
-Pqueue-name
parameter , you can set up a default printer using the
lpoptions -d queue-name
command. For example, the
lpoptions -d lj4p-duplex
command sets the default printer to lj4p-duplex.
Direct (raw) printing
Each printer has a virtual queue through which jobs are sent directly to the printer without intermediate processing by the print server. The name of this queue is derived from the system name of the printer, just add the suffix
-raw
. Alternatively, use the
-o raw
parameter for
lpr
. E.g.
lpr -Plj2b -o raw file.ps
or
lpr -Plj2b-raw file.ps
.
Locales and printing text files
For correct output of text files with accented characters, it is necessary to have the locales set adequately, namely the environment variables LANG and LC_MESSAGES (depending on the CUPS version, the correct setting of both variables is a certainty). For example, for a file containing Czech characters in ISO-8859-2 encoding, the correct setting is:
LANG=cs_CZ.ISO8859-2
LC_MESSAGES=cs_CZ.ISO8859-2
or
LANG=en_US.ISO8859-2
LC_MESSAGES=en_US.ISO8859-2
etc.
Printing from Mozilla/Firefox browsers does not work; documents intended for "letter" paper format
Especially the printers on the 4th floor of Building B tend not to print a job correctly from Mozilla or Firefox unless you explicitly select the paper size as A4 in the print dialog (Ctrl+P) in the printer settings (Properties). This action can also help with non-functional printing of documents that are written in "letter" format. If you are entering a job from the shell, add the
-o media=a4
parameter after the
lpr
command.
Problems with psutils
If you want to print multiple pages on a single page, do not use
psnup
, but use the
-o number-up=COUNT
parameter. The
psnup
program does not generate correct Postscript and you may run into problems with subsequent duplex printing. If for some reason you already have a Postscript that has passed
psnup
, you can try converting it with
ps2ps
(available e.g. on aise in the
gs
module) to a correct Postscript or
ps2pdf
to PDF.
If the conversion with
ps2ps
generates a document that is unsightly compared to the original, you can try to correct the original Postscript with the following command (replace the file names
original.ps
and
processed.ps
with the corresponding names):
$ sed 's/^%%BeginProcSet/%%Page: 1/;/^%%EndProcSet/d' original.ps >
processed.ps
Print A3 to copy4b
When printing A3 documents on the general queues of the listed printers, the printer may be left waiting for the correct paper tray to be selected on the display, as the listed printers cannot automatically select/change the tray to A3 according to the dimensions of the document being printed.
This problem can be solved in several ways: you can use the -a3 queue of the printer where the correct tray is set, or manually set the print dialog to use the "Cassette 2" tray in addition to the A3 paper size. In the case of printing, you can use the A3 queue in analogy or specify the following switches:
-o media=a3 -o InputSlot=PF730B
Problems with duplex Landscape printing
On some printers (e.g. copy5c, copy2a), when printing some Landscape PDF/PS documents (e.g. ISu attendance sheets), the double-sided printing of all pages starting from the second page is rotated ninety degrees to the paper media, which also results in print clipping. The problem can be circumvented by modifying the PS document with the Perl script psmangle.pl. If you want to print a PDF document, you need to apply a tool like pdf2ps to it first.
This problem does not affect single-sided prints or double-sided Portrait prints. It also does not apply to IS printing where the correction is applied automatically.
Booklet printing
Due to the presence of a finisher, the
copy4b
and
copy5b
printers are best suited for this task. Example:
anxur$ lpr -Pcopy4b -o PageSize=a4 -o Duplex=DuplexNoTumble \
-o Collate=true -o KCBooklet=Left -o Fold=True -o Stpl=Center \
brochure.pdf
If the PDF pages are A5, A4 sheets are used for printing (and by analogy for A4). If you need to print multiple copies, we do not recommend using the
-#n
switch, but to send multiple identical print runs sequentially.
