The printer’s 203 dpi resolution may be insufficient for ultra-fine barcode or graphic printing needs. Thermal transfer ribbon replacement introduces occasional maintenance compared to direct thermal printers. Its maximum print speed of 5 ips is slower than some high-end industrial printers, limiting throughput. The lack of advanced wireless connectivity limits flexibility in modern network environments. The memory size is modest, restricting storage of very large or numerous label formats internally. Absence of color printing capabilities confines its uses to black/white labels only.
