A stylus printer is a printer that uses a print needle to strike a ribbon with a print needle to leave text or patterns on the paper. The stylus printer can print several layers, so it is mainly used in industries such as banking, finance, taxation, postal, etc. that need to print tickets. Its advantage is that the price is cheap. The disadvantage is that the printing noise is large and slow, and it can only be used for printing text.
Dot matrix printer
[pin number]
The number of print pins is the number of print pins on the print head of the pointer printer. The number of print pins directly determines the effect of product printing and the speed of printing. At present, the most common products have 24 needles, and earlier needle printers also used 9 needles, but the effect and speed of printing are much less. Some high-end products use dual print heads, but the number of needles per print head is also 24-pin, but the speed of printing can be greatly improved.
[printing needle life]
Since the dot matrix printer prints dots by printing against the ribbon and eventually produces images, the needles are inevitably subject to wear. After a certain degree, they can no longer be used. The life of a print pin is the number of times a print pin can be scrapped before it can be scrapped. Its unit is “second hit/needleâ€. The current product's print needle life can reach 200 million hits/pin, and some even more, can reach 500 million hits/needle. However, there are two issues that need attention. The first is because the frequency of use of each print pin on the print head cannot be exactly the same, so it is certain that some needles will be scrapped first, and some will be scrapped later. Another point is that "billion hits/pins" is a divisor. To know such a large number, the user cannot actually detect and calculate. Therefore, it is also important to pay attention to the free warranty time of the print head at the time of purchase.
[color ribbon life]
The ribbon life refers to the number of standard characters printed by the printer's ribbon (normally 48 dots/character, and if it is a large number, the number of standard characters printed normally will be much smaller), which is generally expressed as “ten thousand/number of charactersâ€.
Ribbon cassette
Although it is completely out of use with inkjet printers and laser printers, it is completely useless. The ribbon printer's ribbon has a long service life and can also be printed. It is lighter, but in fact, due to over-friction, the ribbon that has exceeded its service life will be very fluffy, causing the printer to hang the needle and break it. Seriously affect the life of the print pin, which is outweighed. Therefore, the ribbon must be replaced promptly after it reaches the expiration date.
[paper thickness]
Refers to the thickness of the largest paper that can be supported by the dot matrix printer, and its unit is mm. Stylus printers are often used to print tickets and reports. Bills and reports often require multiple copies of overlay printing. Therefore, when using a dot matrix printer, multiple pages cannot be printed except for the fixed paper thickness of the product. The total thickness of the paper overlay cannot exceed the paper thickness specified by the product.
In practical applications, because of different uses, the thickness of the paper used for printing is not the same. For example, the paper in a commercial invoice is generally thin, and the paper feed thickness and print thickness do not have to be selected too large; In the financial sector, due to the large thickness of passbooks and bills of exchange that need to be printed, products with higher feed thickness and higher print thickness should be selected when selecting.
However, many products currently have a certain limit on the lower limit of the paper thickness. If the paper is too thin, if it is lower than the lower limit, the same problem may occur during printing.
For example, the paper thickness of Epson LQ-1600K4+ is 0.065-0.52mm, while the paper thickness of Fujitsu's DPK 8600E is 2.0mm, which is why many financial departments choose to print passbooks.
Ticket printer
Bill printer is widely used in many occasions to distinguish it from common office laser printers. For example, mall supermarkets print small tickets and invoices, as well as printers of various companies' financial printing VAT invoices, etc. There are many other uses beyond this: for instance, portable ticket printers for traffic police on-site ticketing and financial check printers.
[Maximum print speed]
The maximum print speed refers to the fastest print speed that the receipt printer can achieve. The print speed of ticket printers is identified as CPS, not the ppm used by our common inkjet printers and laser printers. The Chinese used by CPS can be translated as “wordsâ€. The "seconds" means the "number of characters" that can be printed in one second per unit time. If the value is larger, the printer's speed will be faster.
Some small ticket printers that print tickets while cashing in supermarkets use "line/second" as an indicator of print speed.
However, it should be noted that products identified by “words/second†are more commonly referred to as English characters if the product does not specifically indicate that the size is standard No. 5, and some products will additionally identify the printing speed of Chinese characters. The size is also the standard 5 character. If you print characters larger than 5, the number of characters printed in a unit of time naturally decreases.
There is also the use of the highest print speed for printing, the loss of the print needle is larger than the low-speed standard print, so the probability of causing a broken needle is also much greater, and the quality of the print will also have a certain decline.
[rewrite ability]
Bills often need to be copied through multiple writing. Copying capability is the ability of a pointer printer to play "up to several" content on copy paper. The reprint ability of the ticket printer is related to the strength of the product's print needle impacting the print media. At present, the duplication capability of bill printers is generally identified by the “1+X†method. For example, “1+3†means that the product can print up to 4 layers of the duplicated bill and print out the content. “1+6†Naturally, it is possible to print out all the contents on the 7-layer copy-book.
The choice of replication capabilities must be based on the actual situation of the application to choose, such as print VAT invoices need to be 7-line, then the user must choose to have "1 +6" copy capabilities of the product. When purchasing, you must consider the actual application. If you select too many things, the task cannot be completed.
[paper feed method]
The paper feed method refers to the way in which the ticket printer can obtain the paper required for printing. Although different brand products have different names for the paper supply method, we can divide it into two categories according to the reasons for feeding the paper with a dot matrix printer: supply continuous paper by means of gear drag and supply single sheets by the principle of friction. . However, the vast majority of needle printers currently have these two types of paper feed.
There are still a number of products that can automatically feed a single sheet of paper by adding an “automatic sheet feeder†to make printing easier and faster.
[print direction]
The printing direction refers to whether the ticket printer can only print in a single direction during the printing process, or can print in both directions. At present, there are two types of printing directions for receipt printers: one-way logic and bidirectional logic. One-way logic means that the printer's print head can only print in the process of performing one-way movement. Generally speaking, it prints from left to right; bidirectional logic means that the printer prints. The head can print while it can move back and forth in both directions. It is clear that products with bidirectional logical print orientation are faster at printing speeds.

A casserole is a large, deep dish used both in the oven and as a serving vessel. The word is also used for the food cooked and served in such a vessel, with the cookware itself called a casserole dish or casserole pan.
Casserole cooking is generally done in an oven to bake where heat circulates all around the cooking vessel. Casseroles may be cooked covered or uncovered, while braises are typically covered to prevent evaporation.
EF Homedeco can supply difference sizes casserole to meet customer`s request, from round Enamel Casseroles to square casseroles, from seasoned finish to enameling, customer designs can be available.
