1) EPS (which the article just mentioned) is part of Adobe's Document Structuring Convention, which solved the problem of skipping and reordering pages.

>Every DSC-compliant document is indicated by having the comment %!PS-Adobe 3.0 as the first line. This comment is a flag to indicate that the document is compliant. You should never use this comment unless your document really is DSC compliant. There are many other parts to proper DSC. A document which follows the DSC can be manipulated in many ways. In particular, postprocessors can shuffle the pages, print two or more pages on a side, and so on. The printer drivers from some notable companies do not follow the DSC, and their PostScript documents are, therefore, impossible to work with once they've been generated.
2) Inefficiently skipping pages (or being slow) is NOT the main problem with PostScript's Turing completeness!

>Security Issues: In early 2017, Microsoft took steps to prevent exploits based on Word's import "filter" for EPS. Based on the assessment that "EPS files are a legacy format that has largely fallen out of favor in today’s ecosystem", Microsoft disabled the import filter by default in its April 2017 security update for Office. According to PPTools post I can no longer insert EPS graphics into PowerPoint, this update applied to Office 2010, 2013, and 2016/365. Import of EPS files into Office 2007 has been disabled since 2015. The stand-alone Office for Mac is not affected.
>A Jan 2017 post from The Register, We don't want to alarm you, but PostScript makes your printer an attack vector, publicizes the vulnerability of networked PostScript printers. The potential for damaging exploits based on communication between computers and PostScript printers has been understood for years, but was not a serious threat before PostScript printers were networked and accessible over the Internet.
