Precision Marking
A 300-nozzle plate lays text fine enough for a 2.5 mm date code and wide enough for a logo at 12.7 mm. Hold a phone camera over the printed code and the dots read as a solid stroke, not a dotted approximation.
Our Story
How a coder for shops without a fixed line ended up publishing the numbers most handheld printer pages leave out.
Set the printer against a curved aluminum drum, pull the trigger, and the lot code lands in one pass. No fixed line, no jig, no waiting three weeks on a label supplier. Solvent ink sets in 2 to 5 seconds, so your next carton stacks on top of the last one without a smear line.
Handheld coder pages all promise quick-dry ink, so EzyHand prints the seconds, the nozzle count, and both warranty terms on the spec line you read before ordering. One of those terms runs out first, and it belongs to the cartridge you reorder rather than the printer you keep.
Order a spare and check the code on the box: only the H05B cartridge seats in the H50 body, model series H50, model FB20. A bargain third-party refill will not lock into the carrier, so it sits unused on the shelf beside the printer. Type handheld coding machine, portable batch coder, or expiry date printer into a search bar and the same tool comes back each time. Set the print height to 12.7 mm and your date code lands the same size as the ones already stamped on incoming stock.
A small-batch sauce producer marking 400 jars a week moved off pre-printed labels entirely. The same cartridge codes a curved glass shoulder in the morning and the shipping carton that afternoon. That owner now reorders ink against a yield count instead of waiting three weeks on a label supplier.
Every figure on this site traces back to a published EzyHand specification or to a buyer who ran the printer through daily use. Where the spec sheet stays quiet, this site says so rather than filling the gap. Connectivity is the clearest case: the H50 moves artwork over USB, and no Wi-Fi or Bluetooth is confirmed anywhere in its documentation.
The reason the coverage terms sit apart is simpler than it looks. A printer body survives years of dock use; a solvent cartridge is a consumable that ages from the day it is sealed. Filing the two dates separately the hour the box lands is what keeps a nozzle question from turning into a warranty argument nine months later.
