## Printer Names

- Printers are named after the room they are in.
- For the big printers on corridors of J and K floors several virtual printers with various configurations are provided. For example: 
    - jcolor = colored
    - j = black/white
    - jcolor-booklet = booklet

### Credit System

All printers of the institute are connected to a central print server, which logs and counts all print jobs. Before a print is sent to a printer, the system gets the page number and job settings, calculates the costs and checks permissions and credits for the sender. After a successful printing, the credits will be subtracted.

<table id="bkmrk-credits-and-free-pri" style="width: 100%; border-collapse: collapse;"><tbody><tr><td>**Credits and free printing**</td><td>**black and white**</td><td>**color**</td></tr><tr><td>**members of the institute\***</td><td>free</td><td>free\*\*</td></tr><tr><td>**students\*\*\***</td><td>costs</td><td>costs</td></tr></tbody></table>

- Members of the institute are: Professors, Staff, Assistants (!PostDocs and !PhDs), Guests.
- Assistants need to refill the credit (for free) after printing 100 colored pages per semester.
- Students with 'Hauptfach Mathematik' or "Hauptfach Bio Statistic" get free credits worth 20 SFr. per semester. An [I-MATH account](https://www.math.uzh.ch/my/account) is required to print.
- A printjob is counted based on page number, page format (A4 or A3), simplex or duplex and black/white or color.
- Special settings like A3, color or stapling are only available on some special printers like jcolor, k.

[Prices for all printers with different settings!](http://www.math.uzh.ch/li/index.php?id=printer-costs)

#### Charging/Checking Credits

- You can view your credit, your settings and your last 50 print jobs in your account admin panel: [My Math](https://www.math.uzh.ch/my/print-history).
- Users can charge credits at the office **Y27K30**. The credit can be used immediately.
- Assistants can also write an email to the system support (<support@math.uzh.ch>), but in this case it can take a while until you receive the credit.

### Booklets

Printers / Copiers 'jcolor' and 'kcolor' are capable to fold and stamp printouts to create booklets / brochures.

- Mulitple Copies: DO NOT USE 'copies' (print dialog or via commandline '-n num-copies'). Instead use 'Repeat jobs' under advanced options. 
    - [![repeat.job.png](https://wiki.math.uzh.ch/public/uploads/images/gallery/2026-06/repeat-job.png)](https://wiki.math.uzh.ch/public/uploads/images/gallery/2026-06/repeat-job.png)
- Up to 16 sheets of paper can be stitched! If you have more they only get folded.
- Printing booklet with **only** folding (no stamps), might produce outputs where the single folded sheets of paper are one by one and not inserted into each other.

- **Manuals:**
    - [Thinlinc](https://wiki.math.uzh.ch/public/books/public-wiki/page/thinlinc-mdy#bkmrk-booklet)
    - [MacOS](https://wiki.math.uzh.ch/public/books/public-wiki/page/mac#bkmrk-booklets)
    - [Windows](https://wiki.math.uzh.ch/public/books/public-wiki/page/windows#bkmrk-booklets)
    - [Linux](https://wiki.math.uzh.ch/public/books/public-wiki/page/linux#bkmrk-booklets)

## Poster Printing (large)

- ETHZ has outsourced most printing jobs, but you can still print large formats, see here: [https://signprint.ch](https://signprint.ch/)  
    and here for FAQ on ETHZ's decision to outsource etc: [https://ethz.ch/staffnet/en/service/office-supplies-printing-and-mailing/print-publish/futureprint-eth.html](https://ethz.ch/staffnet/en/service/office-supplies-printing-and-mailing/print-publish/futureprint-eth.html)

## Troubleshooting

#### Text replaced by □ 

[![image.png](https://wiki.math.uzh.ch/public/uploads/images/gallery/2026-10/scaled-1680-/image.png)](https://wiki.math.uzh.ch/public/uploads/images/gallery/2026-10/image.png)

In case you printed on k, kcolor, j, jcolor and the text on the printout is replaced by squares or weird characters, do the following:

- **Install GhostScript via Terminal:** 
    - MacOS: `brew install ghostscript` (via Homebrew)
    - MacOS: `sudo port install ghostscript` (via MacPorts)
    - Linux: `sudo apt install ghostscript` (Debian, Ubuntu)
    - Windows: `winget install ArtifexSoftware.GhostScript`
- **Convert the PDF:**
    - MacOS/Linux: `gs -o print.pdf -sDEVICE=pdfwrite -dNoOutputFonts input.pdf`
    - Windows: `gswin64c -o print.pdf -sDEVICE=pdfwrite -dNoOutputFonts input.pdf`
- **Print the Converted PDF:**
    - Now print the newly generated PDF (in the example it is named "print.pdf")
    - The printout should be fine now. If not, please report to `support@math.uzh.ch`
