There may be two reasons for the printer not responding when printing PDF files: first, the printer is not turned on, and second, PDF files are encrypted and cannot be printed directly.PDF (Portable Document Format) is an electronic document format used for cross platform file exchange. It is based on PostScript language image model and can accurately reproduce characters, colors and images in the original.Because it is independent of the operating system, it can be used under various operating systems.With the popularization of the Internet, more and more e-books, product manuals, company documents, network materials and emails are stored in PDF format. One of the reasons why the printer does not respond when printing PDF files is that the printer is not turned on.First, you need to ensure that the printer is properly connected and working.Try pressing the power button to start the printer and make sure all cables are securely connected. Another reason that may lead to no response in printing is that PDF files are encrypted.In this case, when opening or editing a PDF file, you will usually be prompted to enter a password to operate on it.If you want to print directly from a PDF file, you need to enter the password associated with the file.If the password cannot be found or entered correctly, the PDF file cannot be printed.At this time, consider using professional PDF editing software to remove password protection, and then try printing again. In addition to the above two points, there are other factors that may cause the printer to not respond when printing PDF files.For example, updates to the operating system or drivers, network connection problems, firewall settings, etc. may affect the printing function.If you encounter such problems, you can try reinstalling drivers, changing network settings, or adjusting firewall rules to solve them. To sum up, the problem that the printer does not respond when printing PDF files may be related to the fact that the printer is not turned on, PDF file encryption, and many other factors.In order to solve this problem, you need to ensure that the printer is in a normal working state, and enter the correct password for operation.If the problem still cannot be solved, it is recommended to try other methods to restore the normal printing function.
The PDF document is encrypted and cannot be copied or printed. For general encryption, please use the pdfpasswordremove software to encrypt. If you use a digital license to encrypt, you cannot decrypt. The pdfpasswordremove software can be found on Baidu.
Make sure that the power cord of the printer is correctly connected to the computer cable, and turn on the printer power; 2、 Check whether the port setting in the printer properties is correct as the USB port;(For Windows 9x system: "EPUSB1" port in "Control panel" - "Printer" - "Attribute" - "Print to the following port"; if not, select "EPUSB1" from the drop-down menu; for Windows 2000 system: "USB001" port in "Control panel" - "Printer" - "Attribute food" - "Port" - "Print to the following port"If not, please change it correctly. The serial number of the USB port depends on the USB device used, for example, it may be USB003); 3、 If there is no USB port in the printer properties, check whether there is an unrecognized Epson device in the Device Manager;("Control panel" - "System" - "Device manager" - check whether there is an Epson device with a yellow exclamation mark or question mark. If there is an Epson device, please "delete" or "uninstall" it, and then plug and unplug the USB interface again); 4、 After re plugging, the computer prompts to find new hardware. After the driver is automatically installed, it can print normally.Note: It is recommended to turn off anti-virus software and firewall when installing drivers.
