subject: Four Broad Categories Of Specialized Programs Common Dot Matrix Printer - Stylus Printers, Office [print this page] Simple, mature technology, good cost performance, the use of low cost, which are pinned Printer Advantages. In the past, although the noise higher stylus printer, low-resolution, print-pin easily damaged, but in recent years as technological development, the upgrading of the Stylus printer large print speed and reduces the printing noise, improved print quality, make toward the special stylus printer, professional direction, so that in the bank book printing, financial printing invoices, recording scientific data, continuous printing, bar code printing, fast printing and multiple copies of jump in applications such as field production of other types of printers irreplaceable function.
Stylus printer is no different from the surface, but with the need for specialization, and specialization, there different types of dot matrix printer, which are mainly generic stylus printer, passbook printer pin, line pin printers and high-speed needle some printers, the following highlights the characteristics of these types of printers, performance and technology.
Universal Dot Matrix Printer Common dot matrix printer is an early use of a wide range of character printing device, print the number of common scalp for 24-pin, there are two broad lines and narrow lines, the print head moving back and forth in the completion of horizontal metal bars on the line type print. Print width up to 33cm, the general standard of print speed of 50 characters / second, resolution is generally 180dpi, using ribbon printing, friction and drag can be used two ways to go on paper, can print a single page of paper, you can also print the perforation folded continuous paper, ribbon and print media and other supplies low prices. As the electromagnetic hit, the print head to print a long continuous severe fever, but slow print speed, little impact; Also, because common stylus printer wide-format printers in general, compatible with the DOS system, so more suitable for report processing number of general office and financial institutions.
General stylus printer easy to use, if the ribbon and paper are of poor quality or improper installation, easy to needle. When printing characters too light, the mean decline in ribbon rendering capabilities are easily tuck and obstruction of paper, ribbon must be replaced at this time. In addition, the common dot matrix printer ribbon is not uniform, can not substitute each other. General stylus printer has a manual adjustment of paper thickness lever, when the thickness of printing paper changes, be sure to adjust the thickness adjustment lever to adjust the print depth and protect the print pin.
Book stylus printer With the development of various industries of electronic, dedicated to banking, telecommunications, insurance, business services counter passbook stylus printer using a rapid promotion and application of the so-called book, also known as dot matrix printer dot matrix printer paper , compared with other general-purpose stylus printer, passbook stylus printer has the following characteristics:
Horizontal push away paper: horizontal push away paper path design to reduce bending of paper and cardboard printing error caused to advance and retreat of paper with ease, but also makes it possible to deal with extra-thick print media.
Adaptive paper thickness: book stylus printer's print books and other objects are instruments, and different books of different thickness of paper, so the book stylus printer required to print according to the thickness of the different media and automatically adjusts the print gap hit efforts to achieve a clear print of any thickness.
Automatic correction technology: the ability to automatically align the print media, which greatly improved print accuracy, so that operators operate the transfer;
Paper positioning technologies: In order to print format, uniform and car in the paper tray is installed photoelectric sensors to automatically detect the paper of the left and right borders. In the feed sector office set up multiple photoelectric sensor to detect the paper's top position relative to the print paper to ensure the absolute floor flat. And through the printer control software in order to print positioning to achieve a complete and accurate print position.
Magnetic read and write functions: to provide optional built-in magnetic stripe reader can read and write books on the user name, card number, amount and other information, and support the ANSI, ISO, NCR, IBM, HITACHI etc. magnetic stripe format.
Print state recognition: the host or terminal with two-way communication, to the current state of the printer, the error promptly and accurately reflected, and the corresponding treatment. In addition, most of the books specially designed stylus printer automatically stops printing when opening the lid, to prevent disturbance caused by printing errors, while protecting their personal safety.
Other features: Some high-end book stylus printer also offers a number of optional features, such as the two operators to share printers, bar code automatic identification page number, printing magnetic characters such as password protection of confidentiality and decryption, the banks and the use of special symbols printed Fresh -Rom storage technology for automatic Download Upgrade software.
