Traditionally the DB25 parallel port and DB9 serial ports are associated with low speed matrix printers. Special printers are used for printing matrixlike prints such as cash register receipts, which typically are printed using a thermal technology which is almost infinitely quiet compared to a matrix printer. With a dot matrix printer using a typerwriter approach the noise you hear is mostly the actual printing, but with thermal and other technologies like Jet Ink the same type of print can be made using less noise. With newer technologies the connection ports often do not differ much, but there is a tendency in the direction using USB ports instead.
Perhaps one day a printing device can only be connected to one type of port, call it PortX, of which there are many on the computers. When the same port type can beused for most things you can add anything in sufficient numbers to a computer if you need it. Back in the old days you could only have one keyboard (PS/2) and one mouse (DB9), one printer (DB25) and one graphics display (DB15). Today you can have all of those on USB and if you need more just add one as long as you have available USB ports.

What is virtual com port?
A virtual port is a software emulation of a port which normally would be present in hardware. This is most commonly used with modems and printers. Many internal modems emulate a COM port. When modems first became common by far the most common type was an external modem which plugged into a serial port (a COM port) in the back of the machine. Nearly all of the early dial-up networking applications were written with the assumption that the modem could be found on one of these COM ports. While it is no longer necessary for the modem to reside on a COM port, most new modems still emulate one in order to maintain compatibility with these legacy applications. Printers can also reside on a virtual port for much the same reasons. All printers used to plug into a parallel port (an LPT port) on the computer. As a result many legacy programs were written with the assumption that any printers would be located on an LPT port. When USB printers became commonplace it became necessary to allow these USB printers to be assigned a virtual parallel port in order to maintain compatibility with these older programs. This can be configured in the OS in the printers settings and is most often used for DOS-level point-of-sale or data-entry applications.
Is usb ports the same as serial ports?
No. The term serial port refers to the older 9 or 25 pin, male connectors on the back of a PC. They were used for connecting to modems, certain printers, and mice.A USB port, while it is technically a type of serial port, it is incompatible with the old type of serial port. A USB port gets information about the device from the device, while the old type serial port simply transmitted data. USB to serial adapters do exist, but compatibility can be a challenge.
What connectors are used on a parallel port cable?
Many devices have traditionally been connected to a parallel port. The most common usage was for printers. Image scanners, external hard drives, and Ethernet adapters have also been created for the parallel port.
How do we calculate salvage value on printers?
It depends on the type (inkjet, laser, LED page printer, phaser/solid ink, dot matrix, line printer, daisywheel, etc.), age, amount of use/wear, physical condition, and more. The best advice is to speak with a professional printer repair shop to get an idea of what such a printer might be worth. If you have printers that you wish to get rid of for, then you may be able to sell some of them (such as laser printers) to the aforementioned repair shops for parts. Inkjet printers are typically designed to be throw-away items, so if they are not working, they have no practical value.
Margins are different on different printers?
Yes the margins are different on different types of printers as the size of the printer and type of printer are not the same.
Which type of printers can be used with multipart forms?
Dot matrix printers
Type of printers?
laser, inkjet and dot matrix.
Which port type is commonly used for laser printers?
USB 2.0
True or false Dot matrix printers are almost nonexistent now because they have been replaced with inkjet or laser printers?
Type your answer here... true
What type of printers does Printronix produce?
Printronix manufactures three main types of printers. These are line matrix printers, barcode printers and RFID printing. Their main website has lots more information about these three products.
What type of impact printer is used for personal computers?
Dot Matrix printers are the most common impact printers used with personal computers. Daisy Wheel printers are sometimes used as well.
Is dot matrix a printer?
Yes, "dot matrix" is an older type of printer that you don't see much now, because inkjet and laser printers have become standard.
What type of printers should be used to prevent strain on wrist?
Dot matrix
How many type of connector's used in computers?
PS/2 (For Keyboard and Mouse)USBCOM1 and COM2 (serial) PortParallel Port (for Printers)SpeakerMicVideo Port (Monitor Port)Lan Port
What are the characteristics of impact printer?
1 they have very low consumable costs they are very noisy they are useful for printing bulky documents
Which printer type uses small hammers to strike against the paper to leave an image?
Dot-matrix printers. Daisy wheel printers have hammers (pins) that strike against raised type set around the edge of the wheel.
Which type of printer as the poorest print quality because the image is created using fairly large dots?
Dot-matrix printers.
