When POS terminals are considered, the POS paper rolls - which appear to be the simplest part - must still meet certain conditions. Most of us, after making a purchase, only care about the transaction amount printed on the front of the receipt and don't even look at what's printed on the back.
So what conditions must POS paper rolls meet?
- Must be 56mm x 17m in size
- Must use 55gr/m2 THERMAL (KOEHLER) paper
- The core's inner diameter must be 15mm, 1mm thick, and made of injection-molded granules
- The back side must be printed in a single color with the TSEK mark
- Microencapsulated carbonless copy paper rolls must not be used
- Must be approved by the Turkish Standards Institute,
- On the back of the roll, in the middle section, at intervals of no more than 50 millimeters and along the entire length of the roll, the manufacturer's logo (short name or initials) and the paper's number must be printed
- On the back of the roll and at the edge of the paper, in the following order;
- The short name of the approving institution (no more than 4 characters),
- The date and number of the approval,
- The Expiration Date (Month/Year) must be written, preceded by the phrase "Expiration Date (EXP)", and must be no less than seven years out.
- On the back of the roll and on the other edge of the paper, the statement 'Must be stored in boxes that do not let light through and do not damage the paper, in environments where the temperature does not exceed +35 degrees and the humidity is below 80%.' must be included.
