Gloryang PD-A4 Portable Thermal Printer — Inkless Letter Printing
Portable inkless thermal printer for US Letter, Bluetooth, long battery life, 3-roll kit. Ideal for travel and field printing.
Introduction
A truly mobile printing solution can be a game-changer for travelers, field workers, small-business owners, and students. The Gloryang PD-A4 inkless portable printer brings thermal printing into a compact, travel-ready package — letting you print full US Letter (8.5 x 11″) documents without ink, toner, or ribbons. For anyone who needs quick, reliable monochrome output on the go, this purple PD-A4 balances convenience, speed, and running-cost savings in a lightweight footprint.
This unit solves common mobile printing problems: expensive consumables, bulky hardware, and unreliable connectivity. By using thermal media and built-in batteries, the PD-A4 removes ink purchasing and frequent maintenance from the equation, while its Bluetooth and USB options give flexible connectivity for phones, tablets, and laptops. Whether you need emergency contracts signed, receipts, or single-page handouts during travel or meetings, this printer lets you be productive without returning to the office.
Overview
Design-forward and compact, the PD-A4 measures roughly 11 x 4 x 4 inches and ships in a bright purple finish with a padded carrying case. It weighs a little over three pounds and features a slim profile with a built-in paper bin for tidy storage of finished prints. The hardware is intentionally simple — one tray, USB port for tethered printing, and Bluetooth pairing for mobile devices — minimizing buttons and making setup straightforward.
Under the hood is thermal printing technology designed for monochrome output. This inkless approach uses heat-sensitive Gloryang thermal paper (included in a 3-roll starter kit) and two internal 2600mAh batteries to provide up to three hours of continuous printing or roughly 360 pages per full charge. With a rated maximum speed of up to 35 pages per minute, it offers fast single-sided printing when you need it. The PD-A4 is ideal for travelers, field reps, event staff, and students who value portability, low operating cost, and fast, legible text output.
