# Instant printing

With QZ Tray, receipts, labels and documents go straight to the right printer with one click. QZ Tray is part of the Plus and Pro plans.

1. Download QZ Tray from the card under **Settings**, then [Integrations](https://repender.nl/dashboard/integrations), and start it on the computer your printers are connected to.
2. Click **Connect**.
3. Choose your printers: an **A4 printer** for documents such as quotations, work orders and invoices, a **receipt printer**, and a **label printer** with its label size and orientation.

You can use one printer for everything, or a different printer for each type. Your choices are saved in the browser you set them up in, so choose your printers once on every computer or browser you print from.

With the POS, you can also have Repender print the receipt after every sale, and open the cash drawer when the customer pays cash. The cash drawer needs to be connected to the receipt printer.

Instant printing also works for the labels of your parts and products, which you print from the **Parts** and **Products** pages, and for documents such as a repair's work order.

Without QZ Tray you can still print on every plan: Repender opens the document as a PDF, and you print it from there. QZ Tray only saves you that step. If QZ Tray gives you trouble, use that PDF option to get a document printed in the meantime.

## Receipt settings

If your receipts do not print well, click **Advanced settings** below the receipt printer. It has two settings:

- **Columns**: the width of the receipt in characters. Raise or lower it if the receipt prints too narrow or too wide for your paper.
- **Profile**: the type of receipt printer. If certain characters print wrong, for example the Euro sign shows as another symbol or not at all, the profile is usually set to the wrong type. Change it from **default** to the one that matches your printer. Star printers usually need **TSP600**.

## Label size

Labels coming out at the wrong size? Check the label size and orientation next to the label printer. They need to match the labels in the printer. For other sizes, choose **Custom** and enter the width and height in millimetres.

## Troubleshooting

Work through these in order. Most problems are one of the first two.

1. **QZ Tray is not running.** Look for the QZ Tray icon in the system tray (Windows) or the menu bar (macOS). If it is not there, start QZ Tray. Repender then shows "Could not connect to QZ Tray" when you print.
2. **The printer is not reachable.** If QZ Tray is running but Repender shows "Could not connect to" your printer, test the printer outside Repender: print a test page from your computer's own print settings. If that fails too, the problem is the printer or its cable, not Repender. Check that it is on, has paper and is connected.
3. **Repender cannot connect to QZ Tray.** Your browser may have blocked the connection. Reset the site permissions for Repender in your browser and click **Connect** again.

Other problems:

- **Documents print twice**: quit QZ Tray and start it again.
- **The printer stopped working after a macOS update**: some printer drivers, such as Epson's, need Rosetta, which a macOS update can remove. Open Terminal, run `softwareupdate --install-rosetta` and restart the computer.
