HP DeskJet 3720 Printer 不能直接連線WiFi 打印和 WiFi Direct default password

HP DeskJet 3720 printer 不能直接連線WiFi 打印和 HP WiFi Direct 的預設密碼 password Solved 解決: HP WiFi Direct default password : 12345678 廢話: 朋友打來訴說當用手機經 wifi 直接連線(WiFi Direct)他的HP DeskJet 3700 printer去打印時, 問他要密碼, 但他没有設定密碼, 當然地說明書一早就被他丟掉了, 他都從未看過說明書內容 😔(白眼),  幫佢上去HP官網找了一遍,下載了使用手冊、指南都沒有提供相關內容, 有時最簡單最重要的偏偏就是没有, 最後經Google大神爬了一輪各大看板先找到 HP WiFi Direct default password : 12345678. 注意: HP DeskJet 3720 printer 用WiFi 連接打印有兩種方法: 1.  連接你現有Wifi 網路, 可以用HP手機app(如果PC可下載 HP PC 軟件 ) 連接你的打印機跟住輸入你WiFi 網路名稱(SSID)和密碼將它接入你現有Wifi 網路內。 2. 使用WiFi Direct 在手機內的WiFi直接連線去你的打印機, 不經其他WiFi 網路不用任何設定。當啓用printer 上的WiFi Direct (就是按下圖內2的功能鍵等燈號亮起), 然後在手機內WiFi (SSID List) 內直接選擇Printer 的名字,連上後輸入預設密碼12345678, 連上後就可以打印。 建議: 如果只想用WiFi Direct,  可以先關掉 Pinter上WiFi 功能鍵(圖內1的功能鍵), 只開啓WiFi Direct 功能鍵(圖內2的功能鍵), 這樣可以快速接上, 如果同時1和2功能鍵都開啓而你又没有設定好WiFi 設定, 那可要等上好半天才能連上WiFi Direct 。 Other link: 用PC 設定WiFi連接: https://support.hp.com/us-en/product/hp-deskjet-ink-advantage-3700-all-in-one-printer-series/8949779/model/134

Adobe reader DC open file very slow 解決開PDF超慢問題。

Adobe reader DC open file very slow 解決開PDF超慢問題。 (轉載自: https://answers.acrobatusers.com/adobe-reader-DC-slow-q283887.aspx ) Try the following (one change at a time, so what we know what actually caused the problem when it goes away): 1.) Open Reader's preferences and go to the "General" category. Uncheck the two "Show online storage..." options. This will not connect to Adobe's "Document Cloud" when you try to open a document. 2.) Open Reader's preferences and go to the "Documents" category. Set the number of files in the recently used list to 1 (this will remove all your files that you have recently used from that list). If this fixes your problem, then there may be something wrong with one of the files that you've recently used (e.g. a network drive no longer being available). 3.) Open Reader's preferences and go to the "Security (Enhanced)" category and set "Protected View" to "Off"
