I'm wondering whether to buy a plotter with PS(post scripts)

[SKCSKC]

I have been using a "non PS(postscript) plotter" made by HP for many years.There was no problem in printing from Adobe (photoshop, illustrator, indesign etc) of Windows10or7.I would like to purchase a new plotter this time, but I am wondering whether there is PS Plotter or NonPsPlotter . advice please(The usage is the same, printing from Windows + Adobe).

Generally speaking, you get signficantly better and higher fidelity color output printing with PostScript to these devices than if you print via some other mechanism (typically either HPGL or PCL for those devices)! Why, from color-managed applications that support direct PostScript generation for PostScript devices (i.e., InDesign, Illustrator, Photoshop, Acrobat, and even non-Adobe applications such as CorelDRAW, QuarkXPress, etc.), you are not going through multiple color conversions. For non-PostScript devices, applications must convert colors to some RGB values for Windows printer drivers and then the printer driver or more likely, the printer driver must convert those RGB values back into some form of CMYK. Such round-tripping typically does not preserve the original color values. Font quality can also be mucked up if the device doesn't natively support fonts or only supports TrueType fonts when using non-PostScript page description languages.

There are many more issues as well.

FWIW, the highest quality is achieved if you purchase such printer/plotters with a direct PDF RIP (Adobe PDF Print Engine, for example).
