我是惠普打印机的忠实粉丝，我认为总的来说，它们是企业和消费者最好的打印机。但是，它们与最糟糕的软件捆绑在一起，这些软件不仅会使您的系统膨胀并减慢速度，而且对于将计算机连接到打印机（这是任何打印机的主要目标）也没有太大帮助。
如今，许多打印机都是无线的或至少具有网络功能，这意味着您可以插入网络电缆并进行打印，而无需通过USB将打印机连接到您的计算机。如果您今天购买了一台新打印机，这绝对是荒谬的，它会迫使您将其连接到您的计算机进行设置。
不幸的是，设置网络或无线打印机要复杂得多，因为您现在必须处理两个设备之间的各种设备。即使您今天可以打印到您的无线打印机，但如果 IP 地址意外更改或有人在您的路由器上打开了阻止网络上设备之间通信的安全功能，您可能无法从现在开始一个月。从字面上看，有数百件事可能出错。
事实上，我之前写过关于排除 WiFi 打印机故障(troubleshooting WiFi printers)的文章，并提供了六种可能的解决方案来解决大多数 WiFi 打印问题。但是，有些问题只是制造商特定的，此时，最好使用他们提供的诊断工具。
HP Print and Scan Doctor是一款免费软件实用程序，可帮助您快速解决 HP 打印机的大多数打印和扫描问题。该实用程序适用于从Windows XP到Windows 10的所有设备。不幸的是，这个实用程序还没有Mac版本。
该程序检查了一堆东西，实际上取代了惠普过去用于诊断打印机问题的四个独立实用程序。以下是检查项目的快速列表：
连接(Connectivity)性- 如果通过USB 连接(USB)，则确保打印机连接正确，如果通过网络连接，则确保您的计算机实际连接到网络。
设备状态(Device Status)- 检查以确保没有打印机错误，如墨水用完、卡纸、进纸问题等。
驱动程序检查(Driver Check)-确保(Makes)驱动程序没有损坏或丢失。
设备管理器(Device Manager)-检查(Checks)设备管理器(Device Manager)中可能导致问题的问题。
打印队列(Print Queue)-如果有卡住的作业，则清除打印队列。(Clears the print queue)
Port Match/Device Conflicts- 检查打印机的端口设置，并确保与其他驱动程序或打印机品牌的打印机没有设备冲突。
当您启动程序时，它将继续搜索通过USB、以太网或无线连接的任何 HP 打印机。出现后，您可以单击下一步(Next)并继续屏幕，您可以在其中诊断打印机问题。
现在，如果您在让打印机正常显示时遇到问题怎么办？在这种情况下，程序将无法找到您的打印机，您将看到以下屏幕：
根据您想要连接打印机的方式，该程序将为您提供连接打印机的提示。不幸的是，至少在您使打印机联机之前，该程序无法为您提供太多帮助。如果您有无线或网络打印机，但不知道为什么它没有获得 IP 地址，请先使用USB电缆将其连接到计算机。
该程序还有一个名为“网络(Network)”的菜单选项，您可以在其中查看有关网络的高级信息，并且可以禁用防火墙（防火墙故障排除(Troubleshoot Firewalls)）。这似乎是导致通信错误的主要原因，因此他们在程序中内置了该选项。
现在，一旦您的打印机出现在第一个屏幕截图中的列表中，请继续并单击Next。在这里，它将检测您的打印机是否为默认打印机，并为您提供通过单击按钮将其设为默认的选项。
现在要诊断和修复任何问题，请单击修复打印(Fix Printing)或修复扫描(Fix Scanning)。如果您有一台可以打印和扫描的HP All-in-One打印机，那么您可以准确选择导致问题的问题。
该程序将继续并开始分析打印机和您的系统，以查看阻止打印机打印或扫描的问题。如果发现问题，它将列出并帮助您解决问题。如果一切正常，您应该会看到一堆绿色复选标记和打印测试页的选项。
最后，如果打印问题尚未解决，该程序还有一些最后的选择。您可以对防火墙进行故障排除、卸载并重新安装打印软件并获取特定产品的支持信息。
总的来说，它是一款出色的工具，让我希望惠普为他们的打印机创建驱动程序包，就像他们创建这个工具一样：简单、时尚，没有多余的绒毛。如果您在使用 HP 打印机打印时遇到问题，请确保下载并运行Print and Scan Doctor。有任何问题吗？发表评论。享受！
Use HP Print and Scan Doctor to Fix Common Printer Problems
I’m a huge fan of HP printers аnd I think overall they are the best printers for businesses as well as consumerѕ. However, they come bundled with the worst possible ѕoftware that not onlу bloats and slows down your system, but doesn’t rеally help all that much in conneсting your computer to уour printer, which is the main goal of any printer.
Nowadays, a lot of printers are wireless or at least network-capable, meaning you can plug in a network cable and print without actually having to connect the printer to your computer via USB. It’s absolutely ridiculous if you buy a new printer today and it forces you to connect it to your computer for setup.
Unfortunately, setting up a network or wireless printer is far more complicated just because you now have to deal with all kinds of equipment in between the two devices. Even if you can print to your wireless printer today, you may not be able to a month from now if the IP address accidentality changes or if someone turns on a security feature on your router that prevents communication between devices on the network. There are literally hundreds of things that can go wrong.
In fact, I’ve previously written about troubleshooting WiFi printers and gave six possible solutions for fixing most WiFi printing issues. However, there are some issues that are just manufacturer-specific and at that point, it’s a good idea to simply use the diagnostic tools they have provided.
HP Print and Scan Doctor is a free software utility that helps you quickly address most printing and scanning issues with HP printers. This utility works on everything from Windows XP to Windows 10. Unfortunately, there is no Mac version of this utility yet.
The program checks a bunch of stuff and actually replaces four separate utilities that HP used to have for diagnosing problems with printers. Here’s a quick list of items checked:
Connectivity – If connected via USB, it makes sure the printer is connected properly and if connected via the network, it makes sure your computer is actually connected to the network.
Device Status – Checks to make sure there are no printer errors like out of ink, paper jams, feed issues, etc.
Driver Check – Makes sure the driver is not corrupt or missing.
Device Manager – Checks for issues in Device Manager that could be causing issues.
Print Queue – Clears the print queue if there are stuck jobs.
Port Match/Device Conflicts – Checks the port settings for the printer and makes sure there are no device conflicts with the printer like other drivers or printer brands.
When you start the program up, it will go ahead and perform a search for any HP printer connected via USB, ethernet or wirelessly. Once it shows up, you can then click Next and continue to screen where you can diagnose problems with the printer.
Now what if you’re having issues even getting the printer to show up properly? In that case, the program won’t be able to find your printer and you’ll see this screen:
Depending on how you want to connect the printer, the program will give you tips for getting the printer connected. Unfortunately, until you get the printer online at least, the program can’t help you very much. If you have a wireless or network printer and have no idea why it’s not getting an IP address, then connect it to the computer using a USB cable first.
The program also has a menu option called Network where you can see advanced info about your network and you can disable the firewall (Troubleshoot Firewalls). That seems to be a major cause of communication errors, so they have that option built right into the program.
Now once your printer shows up in the list like in the first screenshot, go ahead and click Next. Here it’ll detect whether your printer is the default printer or not and give you the option to make it default by clicking a button.
Now to diagnose and fix any problems, click on Fix Printing or Fix Scanning. If you have an HP All-in-One printer that can print and scan, then you can pick exactly which issue is causing problems.
The program will go ahead and start analyzing the printer and your system to see what issues are preventing the printer from printing or scanning. If it finds problems, it will list them out and help you resolve them. If everything is ok, you should see a bunch of green check marks and the option to print a test page.
Lastly, the program has some last resort options if the printing issues have not been resolved. You can troubleshoot the firewall, uninstall and reinstall the printing software and get support information for your specific product.
Overall, it’s an excellent tool and makes me wish HP created driver packages for their printers like they created this tool: simple, sleek with no extra fluff. If you’re having issues printing with your HP printer, make sure to download and run the Print and Scan Doctor. Have any questions? Post a comment. Enjoy!
