Parallel porti (Centronics) bir vaqtda 8 bit ma’lumotlarni uzatish uchun ishlatiladi. Kompyuterda ushbu port asosan prenterni ulash uchun ishlatiladi, lekin bu boshqa qurilmalarni, masalan, boshqa EHMlarni unga ulash imkoniyatini istisno qilmaydi.

Kompyuterning parallel portlari LPT1 – LPT4 deb belgilanadi.

Iste’molchilar uchun: USB interfeysi, printerning parallel portini samarali ravishda almashtirdi. Shaxsiy kompyuterni va noutbuk ishlab chiquvchilarning ko’pchiligi paralle portni eskirgan deb bilishadi va endi parallel interfeysni qo’llab-quvvatlamaydilar.
