WinPCLtoPDF

WinPCLtoPDF is a portable software application primarily designed to create PDF documents from PCL-formatted files (Printer Command Language). It also offers support for PXL and PRN.
The tool includes only the necessary and sufficient options for performing conversions, and it's intuitive enough to be tackled even by those not familiarized with file conversion software.

Doesn't require installation

Because there is no setup kit involved, you can copy the downloaded .exe object to a preferred directory on the disk or keep it stored on an external storage device to seamlessly launch the application on any computer without setup. It doesn't update the system registry with new entries, need DLLs or anything else to work well, nor does it create items on the computer without your consent.

Create PDFs from PCL, PXL and PRN files

The graphical interface of WinPCLtoPDF consists of the customary file browser that pops up on the screen when double-clicking the .exe or calling its process from a PowerShell dialog. All you have to do is select the PCL, PXL or PRN file you're interested in converting.
PDF documents are automatically created in the same location as the source files, and this cannot be changed, since the tool doesn't have features in this regard. Moreover, batch processing isn't possible, so you can convert only one file at a time. Once the task is done, you can open the new files with your PDF viewer to inspect results.

Evaluation and conclusion

Conversion jobs were performed fast by WinPCLtoPDF in our tests while the tool used minimum RAM and CPU, so it didn't hog system resources. We didn't have any stability issues. On the other hand, it offers a pretty basic set of features for performing conversions. For instance, it cannot convert multiple files at once. Nonetheless, it's speedy and efficient.
