What is an PJL file?
PJL (Printer Job Language) is a file extension associated with Printer Job Language, a language developed by Hewlett-Packard (HP) for managing printers and sending control commands directly to printers.
More Information.
It was initially designed to provide job-level control of printer features such as job separation, paper handling, and device configuration settings. PJL commands are typically embedded within other print job data, such as PCL or PostScript files.
Origin Of This File.
PJL originated from HP in the early 1990s as an extension to PCL (Printer Control Language), allowing for more sophisticated printer management and control.
File Structure Technical Specification.
PJL commands are ASCII-based and begin with @PJL followed by a command and optional parameters. These commands are used to query or set printer parameters, control printing environments, or retrieve status information.
How to Convert the File?
1. Windows: PJL files themselves are typically not converted because they are used to control printers rather than contain printable content. However, if you need to manipulate or convert the print job itself (which may include PJL commands), you can use the following steps:
- Use printing software that supports PJL commands to modify or interact with the print job parameters.
- Convert or manipulate the print data format (e.g., PCL, PostScript) using appropriate conversion tools if needed.
2.Windows:
- Use printing commands (
lp,lpr) with options to send PJL commands as part of print jobs. - Tools like
ghostscriptcan convert or interpret print job data containing PJL commands into other formats.
3. macOS (Mac):
- PJL commands are embedded within print jobs sent to printers.
- Use macOS printing dialogs or commands (
lp,cups) to manage print job settings, including PJL parameters.
4. Android:
- Use Android printing APIs or apps that support PJL for advanced print settings.
- PJL is typically managed by printer drivers and printing subsystems on Android.
5. iOS (iPhone, iPad):
- Use AirPrint-enabled printers that support PJL for advanced print features.
- PJL commands are managed by the printer driver and AirPrint system on iOS.
6. Other Platforms:
- Custom applications or services may be required to interpret or convert PJL commands depending on the platform.
- Consult platform-specific documentation and tools related to printer management and print job handling.
Advantages And Disadvantages.
Advantages:
- Enables printer feature control beyond standard print data formats.
- Provides a standardized method for printer communication across different platforms.
Disadvantages:
- PJL commands can be complex to manage and integrate into printing workflows.
- Compatibility issues can arise between printers from different manufacturers due to variations in PJL command implementation.
How to Open PJL?
Open In Windows
PJL files are not typically opened directly in Windows but are embedded within print job data sent to printers.
Open In Linux
Similar to Windows, PJL files are processed as part of print jobs and are not typically opened directly.
Open In MAC
PJL files are handled similarly on macOS, embedded within print job data.
Open In Android
PJL files are processed by printing subsystems and are not opened directly on mobile platforms.
Open In IOS
PJL files are processed by printing subsystems and are not opened directly on mobile platforms.
Open in Others
PJL files are primarily used within printing environments and are managed by printer drivers and print spooling systems.
