The company's EPSON LQ-690C has a strange problem，It pauses automatically halfway through printing，Printing can resume after canceling the pause，但沒多久又暫停，一頁可以暫停個三次以上，本以為是印字頭附近的灰塵導致列印秀斗，但清完且更換碳帶後，The problem persists。

While updating the website today，I noticed an issue with the sidebar menu，After clicking on item A，the sub-items of item A appear，but after clicking on item B，only the sub-items of item A still appear，After checking in the backend，it turns out the issue was caused by the cache。

Windows的檔案或印表機分享功能，很常會遇到出現「無法存取XXX，You may not have permission to use this online resource。存取被拒。Error messages like ""，There are many related solutions，In the past, many articles suggested turning off "Simple File Sharing" or enabling the guest account to solve it，Recently, however, I encountered a situation where no settings worked。
