Rasterized text on printouts

[eldroiderino]

Hello, my Nextcloud's pdf.js rasterizes the characters when printing PDF text documents, which reduces the print quality considerably. I am using a rather old printer with a TurboPrint Linux driver, which is connected to a local print server. Any help would be greatly appreciated.

Steps to reproduce

1. Print a PDF text document using Nextcloud's inbuild pdf.js
2. Print the same document using Firefox's inbuild pdf.js (with identical printer configuration)

Expected behaviour

All printouts should look the same

Actual behaviour

When printing using Nextcloud's pdf.js, text gets rasterized and characters look blurred
