Printing doesn't work

Symptom

When you try to print a document (invoice, receipt, bill, purchase order, etc.) from Usystems, one of the following occurs:

• The print dialog does not open.
• The print preview shows a blank or incorrectly formatted page.
• The printer does not receive the print job, or the page comes out blank or unreadable.
• You see an error message when attempting to print.

Likely causes

Listed by probability:

1. Print template is missing or not configured for your product — The document type (e.g., invoices) may not have a print template assigned, or the template was deleted.

2. Browser print settings are misconfigured — JavaScript is disabled, or the browser's print dialog has incorrect page setup options.

3. Printer is offline or not responding — The printer is powered off, disconnected from the network, or has a connectivity issue.

4. PDF viewer or print preview cannot render the document — The document contains unsupported content, or your browser's PDF viewer is not working.

5. Print template has a syntax or design error — The template file contains broken formatting or missing data fields.

Fix for each cause

Fix 1: Verify a print template is assigned to your document

In Usystems, each document type must have an assigned print template in order to print.

1. Ask your Usystems administrator to check the print template settings for your product and document type (invoice, receipt, bill, etc.).

   • Go to Settings → Print Templates Open in Usystems
   • Ensure a template is listed and marked as active for your document type.

2. If no template is listed:

   • Your administrator may need to create or import a default template for your product.
   • Contact your Usystems support team if templates need to be restored or recreated.

3. If a template exists but printing still fails, proceed to Fix 2.

Fix 2: Check browser settings and enable JavaScript

Usystems print functionality requires JavaScript to be enabled in your browser.

On Chrome or Chromium browsers:

1. Click the menu icon (three horizontal lines) in the top-right corner.
2. Select Settings.
3. On the left sidebar, click Privacy and security → Site settings.
4. Click JavaScript.
5. Ensure the toggle for "Allowed" is turned ON.
6. Go back to Usystems and try printing again.

On Firefox:

1. In the address bar, type about:config and press Enter.
2. Click Accept the Risk and Continue if prompted.
3. Search for javascript.enabled.
4. If the value shows false, click the toggle to set it to true.
5. Go back to Usystems and try printing again.

On Safari (Mac):

1. In the menu bar, click Safari → Settings.
2. Go to the Security tab.
3. Ensure Enable JavaScript is checked.
4. Go back to Usystems and try printing again.

Reset print dialog defaults:

1. Open the browser's print dialog (Ctrl+P or Cmd+P).
2. In the print preview, click the More settings or Options button.
3. Verify these settings:
   • Margins = Normal or Default
   • Scale = 100%
   • Paper size = A4 or Letter (based on your region)
   • Orientation = Portrait (unless the document is wide)
4. Click Print to send the job to your printer.

Fix 3: Check your printer connection and status

1. Verify the printer is on and connected:

   • Confirm the printer is powered on and shows a "ready" or green light.
   • If using a network printer, check that it is connected to your WiFi or local network.
   • Wired printers should be connected via USB and detected by your device.

2. Test the printer with another application:

   • Open a simple document (e.g., a word processor or PDF) and try to print.
   • This confirms whether the printer works outside of Usystems.

3. Restart your printer:

   • Power off the printer completely (wait 30 seconds).
   • Power it back on and wait for it to fully initialize (typically 1–2 minutes).
   • Try printing again from Usystems.

4. Check print queue (Windows):

   • Right-click the printer icon in the system tray (bottom-right corner).
   • Select See what's printing.
   • If stuck print jobs are listed, click each one and select Cancel to clear the queue.
   • Restart the Print Spooler service:
     1. Press Win+R, type services.msc, and press Enter.
     2. Find Print Spooler in the list.
     3. Right-click it and select Restart.

5. Check printer queue (Mac):

   • Go to System Preferences → Printers & Scanners.
   • Select your printer.
   • Click the Delete button next to any stuck jobs.
   • Try printing again.

6. Reinstall or update printer drivers (if on Windows):

   • Visit your printer manufacturer's website (e.g., HP, Canon, Xerox).
   • Download the latest driver for your printer model and operating system.
   • Install the driver and restart your computer.
   • Try printing again.

Fix 4: Clear browser cache and reload the page

A corrupted cache can prevent the print dialog from loading correctly.

1. Press Ctrl+Shift+Delete (Windows) or Cmd+Shift+Delete (Mac) to open the browser's cache-clear dialog.
2. Select All time from the time range dropdown.
3. Check Cookies and other site data and Cached images and files.
4. Click Clear data.
5. Go back to Usystems and reload the page (press Ctrl+R or Cmd+R).
6. Open the document you want to print and try again.

Fix 5: Try a different browser or export as PDF

If printing still fails:

1. Try a different browser:

   • Download and install another browser (e.g., Chrome, Firefox, Safari, Edge).
   • Log into Usystems in the new browser.
   • Open the same document and try to print.
   • If it works in the other browser, the issue is browser-specific.

2. Export the document as a PDF:

   • In the print dialog (Ctrl+P or Cmd+P), change the Destination from your printer to Save as PDF.
   • Click Save and choose a location on your computer.
   • Open the PDF in Adobe Reader or your PDF viewer.
   • Print from the PDF viewer using your printer.

Fix 6: Contact your administrator or support

If none of the above steps work:

• Contact your Usystems administrator with the following details:

  • Which document type you tried to print (invoice, receipt, bill, etc.).
  • The error message (if any) you saw.
  • Which browser and operating system you are using.
  • Whether printing works outside of Usystems (e.g., in Word or a PDF viewer).

• If you have a support agreement, contact Usystems support with the above information. They can:

  • Verify the print template configuration.
  • Check server logs for errors.
  • Provide a replacement template if the current one is corrupted.

When to contact support

Contact Usystems support if:

• No print template exists for your document type and your administrator cannot restore it.
• The print preview shows content, but the printer does not output anything.
• You see a server error or exception message when attempting to print.
• Printing works in one browser but not others, and clearing cache did not help.
• The exported PDF shows correct formatting, but your physical printer produces a blank page.
