Great question—capturing the exact PPLB commands sent when you click "Print Test Page" is totally feasible, and saving them as a .prn file is the ideal way to dig into the raw printer language. Here are two solid methods tailored for your Argox printer:

Method 1: Windows Print-to-File Workaround (Simplest Approach) #

Since you can’t directly save the built-in test page as a .prn from the printer properties panel, we’ll create a "print-to-file" duplicate of your Argox driver to redirect the test page output:

• Open Control Panel > Devices and Printers (or Settings > Bluetooth & devices > Printers & scanners in Windows 11).
• Right-click your Argox printer, select Printer properties (look for the option with advanced settings, not the basic "Properties" in the first context menu).
• Navigate to the Advanced tab, click New Driver... and follow the wizard to install a duplicate of your Argox PPLB driver (use the same driver files as your current setup).
• Name the new printer something descriptive, like "Argox PPLB - Print to File".
• Right-click this new printer, go to Printer properties > Ports tab.
• Uncheck the current hardware port, then check File: (Print to file). Click Apply.
• Now return to your original Argox printer’s properties panel, click Print Test Page. When the print dialog appears, select your "Argox PPLB - Print to File" printer.
• Choose a save location, name the file (e.g., argox_test_page.prn), and click Save.

This .prn file contains the raw PPLB commands sent to the printer for the test page. You can open it in Notepad++ (enable "Show all characters" to view control codes) or a hex editor to inspect the exact instructions.

Method 2: Live Port Monitoring (For Advanced Capture) #

If you want to capture commands sent directly to your physical printer (without redirecting to a file printer), use a port monitor to log raw data:

• Open your Argox printer’s Printer properties > Ports tab.
• Click Add Port..., select Local Port, then click New Port.
• Name the port something like Argox_PPLB_Log and click OK.
• Use a free tool like RawPrint or a built-in driver port sniffer to log data sent to this local port.
• Go back to the printer properties and click Print Test Page. The tool will capture the raw PPLB commands, which you can then save as a .prn file.

Quick Tips for Inspecting the .prn File #

• PPLB commands typically start with the ^ (caret) character—search for these to identify the start of each instruction.
• Use a text editor that supports extended ASCII characters (like Notepad++) to avoid garbled text from control codes.
• Reference Argox’s official PPLB programming manual to parse specific command definitions.
