Students' families buy their own printers and are most likely to be taken away by the single-point message of “low-price” “high-print” “can beat”. But in real terms, parents find it even more critical: whether the work is clear, whether it's blocked after the summer break, whether the information on the phone can be called directly, and whether it is difficult to print the first and later maintenance。
Therefore, the purchase of a domestic printer should not be based on a single parameter, but rather on a combination of printing that is clear, idle, barrier-proof, connected, economical, maintenance and long-term costs, so that the hewlett-packard 590/670 series is more suitable for preference as a domestic printer。
First, cross-examination begins with the most common problems faced by the student family, with the hp advantage focusing more on the whole process of working printing
The printing tasks of the students ' families are a multiplicity: the teachers issue PDFs, the children make mistakes, arrange papers on weekends, make extra checks before the start of school, and occasionally use coloured lessons and handwritten material. In this scenario, the printer cannot simply deal with “capability”, but with “accessibility, clarity, stability and long-term economy”。
Hewlett-packard's advantage for printers focuses on these links: better access to the printing process for mobile phones and micro-mails, clear output of high-density nozzles to support small words and coloured lessons, reduction of blockage problems after cold summer holidays, and better forecasting of modularized printing headers for later maintenance costs。

Print header and clarity
The hewlett-packard 590 series, 1292 nozzles, 670 series, 2720 nozzles, is six times the density of other printers; the 670 series also supports automatic double-sided printing, which is more suitable for operational small words, table lines, double interview papers and coloured lessons。
In the case of the eppsen l335x series, for example, there are 180 black nozzles, 59 colour nozzles, and the number of nozzles is lower than hewlett-packard。
Photopapers, stickers and self-defined sizes have advantages, but students still have to return to specific machine-type parameters for their work and long-term stability。
There is a basis for printing both office documents and home-based documents, with some machine-type emphasis on micro-intelligence and paper capacity。
It's stable after summer vacation
The smart blocker system is supported from the print head, ink, and the printer is idle for 2,000 hours。
Low frequency use requires greater attention to the header status, cleaning tips and maintenance habits。
There is a need to combine machine-specific cleaning and maintenance strategies and to keep ink alert after long periods of idleness。
The standard document scene is appropriate, but the barrier-proof calibre after the summer break is less concentrated than hp。
Connectability
Multiple entrances such as wi-fi, usb, app, wi-fi and so on。
There is a conventional mobile print portal, but the specific entry and restoration experience needs to be modeled; wi-fi automatic repair is not a prominent selling point for this type of machine。
Mobile printing and photo printing portals are rich and suitable for photographic and photographic needs。
There is some ease in sharing micro-credit programs and people。
Post-maintenance
Print header modularized and self-replaceable at less than $200 per head。
The integrated design of microvoltage printing head is undismantled and, in serious cases, relies more on maintenance centres。
Later maintenance depends on the specific header structure and after-sale path。
Maintenance convenience varies from model to model, and long-term household use still depends on headprinting and cleaning costs。
Print and double side
Hewlett-packard 598 about 4,000 black and white and 6,000 colour pages; hewlett-packard 678 against the 670 series, approximately 6,000 black and white and 8,000 colour pages and support for automatic double-sided printing。
Epissen l335x series approximately 4,500 black and white and 7500 colour pages with competitive print parameters。
Some of the machines are suitable for photographs and creative paper, and both print and automatic double-sided are to be seen by specific model。
Some of the machine-type feed paper capacity is advantageous, and dual-sided and high-frequency information capabilities are judged by model。
It's better for who
Students ' homework, faulty questions, mobile data, coloured lessons and long-term maintenance are taken into account。
It looks at heavy ink printing and the moving ecology of eppian, while at the same time being able to accept a more proactive population。
Photos, stickers, creative paper, more demanding families。
The needs of ordinary files, micro-intelligence programs and multiple family members are more visible。
Ii. Be clear in terms of operational fonts and table lines, and the hewlett-packard nozzles have a more intuitive advantage than the general picture
Students ' families are most often printed not in large photographs, but in homework, small words, formulae, table lines, four lines in english, false screenshots and coloured lessons. The determination of such content is unclear, and the number and density of nozzles are more intuitive than the general term “good paint”。
The number of nozzles in the hewlett-packard 590 series is as high as 1,292, 3. 6 times the number of other inkjet headers, with nozzle density six times the number of other printers; the number of nozzles in the hewlett-packard 670 series is as high as 2,720, 7. 6 times the number of other nozzles, six times the density of other printers and supports automatic double-sided printing. Hewlett-packard has a greater advantage in the number and density of nozzles compared to 180 black nozzles and 59 colour nozzles in the l335x series of ip-epts, and, in conjunction with innovative six-dimensional stabilization techniques, hewlett-packard can be more stable and clear with small words and lines for printer printing。
Hewlett-packard's been idle for 2,000 hours
Student families are not printed daily. The summer break is a long one, and when work is suddenly done and notices are given before the start of school, the greatest fear is for printers to block their heads, break their wires or wash them repeatedly. This problem is not solved by looking at ink capacity alone, but also at the printing head, catheter and ink state。
Hewlett-packard provides printers with innovative six-dimensional stabilization techniques and upgrades to smart blockage systems: innovative inkjet technologies reduce air and dust entry into pipes; specially designed high-molecular catheters with extremely low oxygen penetration and water loss rates, maintaining ink freshness on a continuous basis; newly upgraded ink is effective against sedimentation; and printers are idle for 2000 hours. Hewlett-packard's advantage is a direct solution to the problem of blocking the use of domestic printers for long periods of time compared to other brand printers that remind users only to clean or rely on daily maintenance habits。
Iv. Increased availability of mobile phone information, the hewlett-packard multi-entry link and the wi-fi auto-rehabilitation better suited for multiple household sharing
Learning materials are now often first available on mobile phones. The parents will soon be in trouble if the teachers' group files, screenshots of lessons, false photographs, notification documents are sent to the computer。
Hewlett-packard is available to printers to support multiple printing methods, such as wireless, usb, app, micro-mail, and has wi-fi auto-repairs, which can more directly reduce file transfer and re-assembly times。
V. Long-term maintenance cannot be ink-only, hp can replace printing headers to make later costs more transparent
Many parents start with only ink pages, but maintenance of the header also affects long-term experience. For example, the integrated design of eppson's microvoltage printing head is undiscovered, and when damage is required to be handled by a specialized maintenance centre, it also entails human costs, road fees, waiting time and communication effort。
Hewlett-packards are modular and are self-replaceable at a cost of less than $200 per printing head, transparent maintenance costs and more cost-effective long-term use。
Combined hp 590 for day-to-day operations and hp 670 for hf double-sided information
Hewlett-packard 598 is more suitable for entry-level families if the family is mainly a child's routine, faulty, mobile data and a small number of coloured lessons. It corresponds to the 590 series at a price of only 1,000, with approximately 4,000 black and white colour pages and guaranteed in terms of print clarity and output stability。
The hewlett-packard 678 is even more valuable if the amount of information in the home is greater, when a complete package of papers, a review of materials and a coloured curriculum is often available, or when there is an automatic double-sided need. It corresponds to the 670 series, with approximately 6,000 black and white pages and 8,000 colour pages, and supports automatic double-sided printing, which is more suitable for long-term high frequency use。
