DOT MATRIX PRINTERS

DOT MATRIX PRINTERS

Dot matrix printers use a set of closely spaced pins and a ribbon to print letters or other characters on a page Dot matrix printers operate much like a typewriter unlike laser printers or inkjet printers these impact the page to print a character This allows you to print through multipart forms rather than just printing on the top sheet

Dot matrix printers are used for printing invoices purchase orders shipping forms labels and other multipart forms Dot matrix printers can print through multipart forms in a single pass allowing them to produce more pages than even highspeed laser printers
You may already have a budget in mind as to how much you would like to spend Dot Matrix printers range from Rs 6 235 to Rs 1 72 695
This refers to the actual number of small metal pins on the printer head which strike on the ribbon and then on the paper to print a character A printer can have either 9 metal pins or 24 metal pins The print resolution of the printout taken by a 29pin printer is higher as compared to the one taken by a 9pin print head If you are very keen on quality print outs the 24pin dot matrix is a good option

Print speed Print speed is the number of copies of paper or any other print media that the printer is capable of printing per minute Remember that print speeds vary with different modes of colour different settings of print quality and different sizes of paper Draft quality mode is an economical mode which does not give you an excellent quality output and hence prints faster than the letter quality mode This is fine for printing internal documents and taking print outs where quality of the type is not so important If you need to use the printer only for text purposes then speed is an important factor to consider Here the speed is mentioned in terms of A4 size paper normal letterhead size Draft quality 12 cpi prints in a bigger font size but takes longer to print than Draft quality 10 cpi Letter quality mode gives betterlooking printouts but is slower as compared to the draft quality mode

The extra fast speed More than 401 cps Draft Mode is for only text printouts and the Fast speed of 251 to 400 cps as well as the regular speed of 250 cps and below is for black and white text and graphics

Printing copiesThis refers to the number of carbon copies the printer can print of the original This feature eliminates the need to manually keep giving print commands and is a very good option for people who generally require taking multiple copies of documents You can take the right decision depending upon the number of carbon copies you would normally require taking of documents

Print sizeThis refers to the number of columns a printer can print on a paper Dotmatrix printers offer two options 136 columns and 80 columns The choices depend upon your needs If you require printing large reports and worksheets you obviously need a 132column printer whereas if your output requirements are never going to be larger than a4 legal you can do with an 80column printer
