Plotters that accept HP-GL files may require PLT rather than a PostScript print file. Converting the drawing lets you send its vector paths as plotter commands.
What the PS format is
PS is a page-description format based on PostScript, an Adobe language for describing text, vector graphics, and raster images. Desktop publishing and illustration programs, including Adobe Illustrator and CorelDRAW, can create PS files; print systems also produce them for printers and workflows that use PostScript.
What the PLT format is
In graphics workflows, PLT usually means a plotter file containing HP-GL or a related HP-GL/2 command set. Plotters use those commands to move the pen, draw lines, and select pens. PLT is useful when a plotter workflow expects this command format instead of a page-description file such as PS.
How to convert PS to PLT
Online on 101convert.com
- Upload the PS file or files and select PLT as the output format.
- Start the conversion, then download the resulting PLT file or files.
Several files can be converted in one batch. The per-file size limit is shown on the page. Conversion runs on the server with Inkscape.
Offline with desktop software
pstoedit is an open-source command-line option for Windows, macOS, and Linux; it requires Ghostscript to interpret PostScript. Install both programs, then run:
pstoedit -f hpgl input.ps output.plt
Replace the filenames as needed. If the installed pstoedit build does not recognize hpgl, check its listed output drivers; available formats depend on the build.
In commercial CorelDRAW versions that support both PostScript import and HP-GL export, use File → Import to open the PS file, then File → Export and choose the HPGL/PLT format. Export-filter names vary by version.
Quality and compatibility
PLT carries plotter paths and pen commands, not the full page-rendering features of PostScript. Gradients, transparency, embedded raster images, and complex fills may be dropped or approximated; text can also change if fonts are unavailable. Check the output in a plotter-aware viewer or software and verify page size, scale, and pen mapping. Confirm that the destination device accepts the HP-GL or HP-GL/2 dialect produced.
