Specifications
Everything you need to know, no manual required
| Metric | What It Means | Your Advantage |
|---|---|---|
| Print methodThermal Transfer | Uses ribbon for more durable print. | Match media (and ribbon, if TT) to this method. |
| Resolution203 DPI | Print density. 203 dpi is standard shipping; 300/600 dpi is finer text and barcodes. | Higher DPI costs speed on Datamax I-46xx class machines. |
| Print speed4 ips | How fast the printer can move media (OEM max). | Industrial 10–12 ips desks outrun a 4 ips LP2844 on bulk batches. |
| Max print width4" | Widest media this model can print. | 4″ class takes standard 4×6 shipping labels. |
| Print languageEPL / ZPL | Command language the host/app speaks (ZPL, EPL, DPL, IPL, ESC/POS, DYMO, …). | Match this to your software — or call (312) 416-1518. |
| Typical media4x6 TT ribbon | Stock this class is built for. | Do not load DYMO cassettes in a Zebra, or 4×6 rolls in a 2-inch/receipt printer. |
| Media width1.00″–4.25″ | Label + liner width this model can track (OEM). | 4×6 shipping stock is 4″ wide. 2-inch desks cannot take it. |
| Max roll OD5″ (127 mm) | Largest media roll that fits the cover. | Desktop 5″ rolls are not industrial 8″ OD stock. |
| Core1.0″–1.5″ | Cardboard tube the OEM lists for this desk. | TPO 1″ desktop 4×6 packs fit this class. 3″ industrial rolls do not. |
| Media thickness0.003″–0.007″ | Label + liner thickness from the OEM sheet. | Thick tag stock outside this range can jam or print light. |
| Max print length39″ | Longest label the standard memory can image (OEM). | A 4×6 shipping label is well under this limit. |
| Media sensorsGap, black mark, and notch | How the printer finds the gap or black mark. | Die-cut 4×6 uses the gap sensor; black-mark stock uses the reflective sensor. |
| Memory (OEM)8 MB Flash, 8 MB SDRAM | Standard Flash / RAM on the public spec sheet. | Inferred-public-spec — this refurbished unit is not a TPO lab measurement. |
| Ribbon (TT)1.33″–4.3″, 74 m, 0.5″ core | GC420t ribbon from the OEM sheet. | DT GC420d SKUs skip ribbon. |
| Connectivity (typical)USB | Ports commonly on this class. This refurbished unit’s exact ports are the variants on the buy box. | Pick USB vs Ethernet vs Wi-Fi in the buy box when this listing offers Connection options. |
| Warranty2-year included | Parts and labor on refurbished printers from TPO. | Optional 3-year add-on SKU at checkout. Not a 5-year upgrade. |

FAQ
Questions people ask before buying
Quick answers before you add to cart.
Every unit passes a full functional test on intake, print quality, connectivity, and mechanical parts, then a second test right before it's packed and shipped. You'll get an intake report noting exactly what was checked. This isn't a "used, as-is" listing.
Both cover parts and labor. The 2-year is included free with every printer. The 3-year extended warranty is an add-on at checkout if this printer runs regularly in a business.
Use the compatibility checker on this page when shown. Pairings are inferred from public specs, not a TPO-tested guarantee. Call (312) 416-1518 (Mon–Fri 10am–6pm CST) before you buy if you are unsure.
Use direct thermal 4×6 (or the sizes in Compatible Media) for direct thermal desks. Thermal transfer models need ribbon. Confirm width in Specs.
Every printer includes free install support by phone or email for the life of the printer, not just a return window. Most setups take about 10 minutes. Start with Setup Studio, or call (312) 416-1518 (Mon–Fri 10am–6pm CST).
Ask for an RMA within 30 days of receipt. A restocking fee applies. The returns page has the fees and what we cannot take back.
Orders placed before the daily cutoff (shown live in the buy box) ship the same day on business days. You'll get tracking as soon as it leaves our warehouse.
