- PCL prioritizes speed and compatibility, with device-dependent output.
- PostScript offers consistency between printers and better graphic detail.
- PDF preserves the document and coexists with PCL/PS in the print flow.
- Installing both drivers provides flexibility for every type of work.
If you have ever had to install a printer and see several drivers and have hesitated between PCL and PostScript, you are not alone.It is a very common doubt: Why are there two controllers? What is each one for? Is it advisable to install both? On a day-to-day basis, these decisions impact the speed, quality and consistency of what you print.
In the following lines we explain, in detail and without beating around the bush, what PCL and PostScript are, how they differ and when to use each one.You'll see that it's not about "better" or "worse," but rather about choosing the right tool based on the type of document, the environment, and the printer. We'll also explain why it makes sense to install both drivers in many cases and what practical implications this entails.
What is PCL (Printer Control Language)
PCL is a page description language created by Hewlett-Packard in the 80s and widely adopted by the industry.. It was born as an open (unregistered) language and, with There, It became a de facto standard supported by the vast majority of manufacturers and by a multitude of OS, making it easy to use the same printer in different environments.
An essential feature of PCL is that it is “device-dependent”. In practice, this means that the controller takes advantage of the hardware of the printer to generate part of the print data (for example, fills, underlines or the rendering of some fonts), so that The computer processes and sends the work quickly and the printer completes the page layout.
This brings with it two very tangible consequences: on the one hand, Printing is usually fast and efficient in terms of load on the equipment; On the other hand, two different printers may resolve certain graphic elements slightly differently, so the same work may not look the same on different models.
Another practical advantage of PCL is that files in this language contain commands ready to be interpreted directly by the printerIn many scenarios, no intermediate conversion is necessary: You can store a PCL file and send it as is to any PCL-compatible device for printing., which is useful in automated workflows.
For all the above reasons, PCL is usually the most recommended option for everyday use.: Office documents, texts, forms, and work where speed and general compatibility are paramount, with driver functions that are often “simpler” to manage than those of its alternative.
Nota: PCL is a trademark of Hewlett-Packard Company, and its extensive historical support explains much of its omnipresence in mixed printer fleets.
What is PostScript (PS)
PostScript is also a page description language, designed by Adobe in the early 80s and marketed since 1984.Its foundations date back to research in the late 70s, and since then it has been widely used in graphical environments, especially on Macintosh platforms and professional design applications.
The big conceptual difference is that PostScript is “device independent”. Instead of delegating the creation of elements to the printer hardware, the language itself fully describes the page, so the final result tends to be consistent when printing the same file on different models or brands compatible.
In the visual field, PostScript stands out for its fine handling of graphic objects.In many cases, vector elements and complex compositions are reproduced in greater detail than with PCL, making it a highly valued choice for graphic arts, prepress proofing, and workflows where the Fidelity is the priority.
The evolution of language has also brought about significant improvements.: With PostScript 3 came notable advances in image quality and color management compared to previous versions, reinforcing its role in professional environments and workflows where color and gradients require precision.
There are, of course, drawbacks.: Processing PostScript jobs may be slower, the files tend to be larger and the memory requirements greater; and although it is very popular in Mac and graphics software, it is not as widespread on all platforms as PCL.
Key differences and relationship with PDF
Both PCL and PostScript are PDLs (Page Description Languages), but they approach printing with different philosophies.. PCL delegates part of the work to the printer and prioritizes efficiency; PostScript defines the page completely and seeks absolute consistency of output across compatible devices..
This difference is noticeable on several fronts: with PCL, The same job may vary slightly depending on the printer model, and Graphics quality depends more on the device; with PostScript, Files tend to print almost identically on different machines, something that is highly valued when doing internal tests and then sending them to an external printer.
Platform compatibility also makes a difference. PCL is widely supported by “almost everything” and is a safe bet in heterogeneous environments; PostScript, although very present in Mac and design ecosystems, It is not available to the same extent on all platforms.
And where does PDF fit into all this? Although many workflows today pivot on PDF, it is still closely related to PostScript. PDF is a format multi-platform designed to faithfully preserve The document (with fonts, images, and layout) may include interactive elements and has evolved version after version to improve features and quality; in practice, has replaced PostScript in many scenarios of exchange, although the logic of “describing” the page is still there.
Summarizing this relationship: PCL is the workhorse for general productivity, PostScript is the bet consistency and graphic detail, and PDF the universal container that preserves the integrity of the document throughout the workflow.
Advantages, disadvantages and compatibility in practice
If we look at the balance of pros and cons, PCL and PostScript have very clear strengths and limitations.Choosing the right one depends on whether you're looking for speed and compatibility or maximum fidelity and uniformity across devices.
Common strengths of PCL (derived from its device-dependent design and broad support): sending speed from the computer, lower consumption of computer resources, great multi-vendor compatibility y ease of use for everyday work.
- Agile processing: The host computer usually “clears” the job quickly and the printer finishes the page.
- Extended Compatibility: Many manufacturers and operating systems support it without problems.
- Ideal for office automation: texts, forms and recurring documents from day to day.
Typical PCL Limitations: The same file may look slightly different on different printers, Graphics quality depends more on the device and, furthermore, in many Macintosh environments it is not so supported like other languages.
- Variation between printers: the same work may not be identical in two models.
- Hardware-dependent graphics: Fills, underlines, or certain fonts may vary.
- Uneven support on Mac: In practice, this is not the standard option in most Macintosh environments.
PostScript Strengths: consistent output between compatible devices, graphic objects often richer in detail y great compatibility with macOS platforms and professional design applications.
- Coherence between teams: The same file prints practically the same on different machines.
- Better graphics processing: Vectors and color benefit, especially with PostScript 3.
- Natural lace in Mac and graphic arts: widely used in these ecosystems.
PostScript Limitations: jobs may be processed more slowly, files and memory requirements are larger, and Its cross-platform presence is not as broad as PCL's.
- Unlimited: Processing may be slower.
- Size and memory: larger files and greater demand for resources.
- Availability: It is not as widespread on all platforms as PCL.
A useful note for professional flows: PostScript consistency is especially valuable if you test on an internal printer and then send the same file to production at a print shop.Avoiding surprises between teams is often more important than processing time.
Configuration, parallel drivers and recommendations
The good news is that PCL and PostScript are not mutually exclusive: you can install both drivers on the same computer.. In fact, It is a common practice because they complement each other: You use PCL for everyday documents and PostScript when you need higher fidelity in PDFs or large images..
There are manufacturers that officially offer both controllers for their current models.For example, some industry vendors' e-STUDIO portfolios offer easy downloads of both PCL and PS, allowing the user to choose based on their needs; this reinforces the idea that having both provides flexibility without the added cost of complexity.
It is important to keep in mind that the same document may be printed differently depending on the driver.. Even if you launch it from the same program, PCL and PostScript interpret certain objects differently and therefore You can get the same, similar or, in specific cases, different results.; if appearance is critical, test on the “target” controller first.
On some multifunction devices, certain options can only be touched from the device's touchscreen.. It's common to see an asterisk (*) in documentation that indicates settings that aren't available in the printer driver or remote interface, but are available on the printer's panel. If you can't find a setting in the driver, check the device's menu.
Another term you'll encounter in PostScript environments is PPD (PostScript Printer Description)A PPD file describes the capabilities and restrictions of a particular PostScript printer (paper sizes, trays, color, duplex, etc.), and the driver uses that information to present the appropriate options to the user and generate jobs compatible with the device.
Quick usage tipsFor general office work and speed, go with PCL; for desktop publishing, graphic arts, and complex PDFs, choose PostScript; if you work on a Mac or with design applications, PS is likely a better fit; if you print the same file on different models and care about the same output, prioritize PostScript.
An additional operational detail about PCL that can save you timeIf your workflow includes unattended printing or printing from systems that generate "ready-made" data, remember that you can save files in PCL and send them directly to any compatible printer, without intermediate conversions; it's a simple way to standardize output.
And don't lose sight of coexistence with PDFAlthough PDF has replaced many uses of PostScript in document exchange, how the file is interpreted and processed when it reaches the printer is still crucial; that's why it makes sense to choose the driver that best respects what you see on screen and to have both available when your variety of jobs requires it.
Finally, remember the issue of brands and supportPCL, a registered trademark of HP, enjoys widespread support among manufacturers; PostScript, owned by Adobe, is the historical standard in design environments. This heritage explains where each option shines and why almost all serious vendors include both in their catalogs.
Understanding PCL's "device-dependent" approach versus PostScript's "device-independent" approach is essential for making informed choices.: speed and compatibility for daily work, compared to coherence and detail for projects where aesthetics ruleThe ideal is to install both and select the most appropriate option for each print, which is what they're there for.
