Dot Matrix Printer for Balance and Lab Instrumnets, 58mm

Dot matrix printers, although old-fashioned, continue to play a vital role in compliance with 21 CFR Part 11 in USP-regulated labs by: · Enabling hardcopy audit trails · Reducing dependency on electronic records. · Supporting data integrity and regulatory inspection readinessRole and Importance of Dot Matrix Printers ✅ 1. Permanent, Unalterable Records· Dot matrix printers use impact printing to generate hardcopy records (often multipart with carbon copies).· These physically printed records are tamper-evident and unalterable, which supports data integrity.✅ 2. Printed Audit Trail Compliance· FDA 21 CFR Part 11 requires a secure, printed, time-stamped audit trail.· While electronic audit trails are primary, printed audit trails from dot matrix printers offer a secondary physical backup, which is sometimes mandated or preferred in regulated labs. ✅ 3. Legacy Systems & Instruments· Many older analytical instruments and lab devices used in pharmaceutical QC/QA still rely on "Log Books" and same is to be replaced by to dot matrix printers.· Keeping these printers ensures continuity and compliance with upgrading to newer systems that require extensive Part 11 validation. ✅ 4. Minimizing Electronic Risk· In environments where full Part 11 electronic system validation is not feasible, using paper records from a dot matrix printer is a cost-effective and compliant workaround. ✅ 5. Data Backup During System Failures· Dot matrix printers are valued in critical systems where real-time, uninterrupted printing ensures that no data is lost even if the main system crashes or loses power. U.S. Pharmacopeia (USP) Context USP chapters (like <1058> on Analytical Instrument Qualification) emphasize data integrity and system suitability. In this context: · A dot matrix printer serves as a qualified accessory for generating traceable, contemporaneous records. · It helps in ensuring ALCOA principles (Attributable, Legible, Contemporaneous, Original, Accurate) are met for data integrity. Printing compliant with ISO/GLP.Dot Matrix Printer can print measured values, time, signature information as well as model and S/N of the balance, ID of the user together with other informations of the selected function. Editable header and footer.Built-in clock:Built-in clock enables printing time and date information even with a balance that doesn't have a clock function.Various operating modes:• DIRECT. Prints out current weight value• TARE/NET/GROSS. Prints out these values separately.• SUM. Prints out the total value of samples• AVERAGE. Prints out the average of samples• FORMULATION. Print out each sample's weight independently when mixing samples• PIPETTE CALIBRATION. Calibrate capacity of pipette• USER DEFINED. The operator can set a multiplicative coefficient• COMPARATOR. Prints out weight value only when inside a defined range• AUTOMATIC TIMING. Prints out weight value at defined time intervals.
