POSTEK GX2 — Frequently Asked Questions
What printing method does the POSTEK GX2 use?
The POSTEK GX2 does both. In thermal transfer mode it prints through a ribbon for durable, long-life labels; in direct thermal mode it prints straight onto heat-sensitive stock with no ribbon at all, which is how most shipping labels are produced.
Which thermal transfer ribbons fit the POSTEK GX2?
The POSTEK GX2 takes thermal transfer ribbons up to 4.33" wide, up to 984 ft (300 m) long, on a 1" core, wound coated side out (CSO). Wax suits coated paper labels, wax-resin handles synthetics and heavier handling, and full resin is the choice for chemical, solvent and outdoor exposure.
Which label sizes can the POSTEK GX2 print?
The POSTEK GX2 accepts media up to 4.41" wide, with a maximum print width of 4.25". Any narrower label will run as well, so long as the roll core and outside diameter also fit the media bay — width alone is not enough.
Which roll cores and diameters suit the POSTEK GX2?
The POSTEK GX2 takes rolls on 1.5" / 3" cores, with a maximum roll diameter of 6". A roll on a larger core will not seat on the spindle, and one over the diameter limit will not let the cover close.
Does the POSTEK GX2 take 3-inch core rolls?
Yes — 3" cores are the industrial standard and the POSTEK GX2 is built for them, which is what lets it hold the large-diameter rolls that keep reload stops down.
Why won't my label roll fit the POSTEK GX2?
Three things stop a roll loading in this printer: the roll is over 6" in diameter; the core is not 1.5" / 3". Label width is usually the first thing people check and the least likely culprit — core size is the common one.
Can the POSTEK GX2 print on synthetic or outdoor labels?
Yes. Because the POSTEK GX2 prints thermal transfer, it can image polypropylene, polyester and other synthetic facestocks that direct thermal printers cannot mark. Pair them with a wax-resin or full resin ribbon; wax will not anchor properly to a synthetic surface.
Where can I buy labels and ribbons for the POSTEK GX2 in Canada?
Vantage Labels stocks blank thermal labels and printer ribbons that fit the POSTEK GX2, shipped from Canadian stock. Everything listed on this page has been checked against the printer's published media specifications — width, core, roll diameter and ribbon format — rather than matched on the printer's name.
