گوگل پیکسل از سیم کارت eSIM پشتیبانی می کند:بدون سیم کارت

رویداد معرفی گوگل پیکسل ۲ پر از خبر بود. انتظار بود در این رویداد چند غافلگیری اتفاق بیفتد که رخ داد و یکی از آنها پشتیبانی این گوشی از ای سیم (eSIM) بود.

پیکسل ۲ و پیکسل ۲ XL از تکنولوژی نانو سیم (nanoSIM) سنتی پشتیبانی می کنند که در سال های گذشته و گوشی های هوشمند عادی دیده ایم. اما علاوه بر این، آنها به فناوری جدید ای سیم (eSIM) نیز مجهز شده اند. تکنولوژی ای سیم (eSIM) به شمااین  اجازه را می دهد تا به سیم کارت فیزیکی، شبکه و خدمات حامل نیاز نداشته باشید. این فناوری قبلا در ابزارهای مانند ساعت های هوشمند و تبلت ها استفاده شده بود، اما این اولین بار است که در گوشی های هوشمند ظاهر می شود.

تا زمانی که شرکت های دیگر فناوری جدید را قبول نکنند، تنها مشترکین پروژه FI می توانند از تکنولوژی ای سیم (ESIM) در پیکسل ۲ استفاده کنند.

این تکنولوژی جدید بدون شک خوب است. اما تنها یک گروه کوچک از مردم در ابتدا قادر خواهند بود از آن استفاده نمایند. به عبارت دیگر، در حال حاضر، قابلیت ای سیم (eSIM) محدود به مشترکین پیکسل ۲ و پیکسل ۲ XL در پروژه Fi خواهد بود.

چیزی که وجود دارد این است که گوگل می تواند کاری انجام دهد تا دیگر حاملان (carriers) از تکنولوژی ای سیم (eSIM) برای شبکه های خود استفاده کنند. به همین دلیل، در کل چیز خوبی است که ما یک قدم به آینده نزدیک و در حال فاصله گرفتن از سیم کارت های فیزیکی گذشته هستیم.

با فرض اینکه گوشی شما در پروژه Fi قرار دارد و همچنین پیکسل ۲ خود را از قبل آماده کرده اید، تنظیمات در گوشی جدید بسیار ساده است. چون گزینه ای برای استفاده از پیکسل ۲ بدون سیم کارت (SIM-free) در طول فرایند نصب وجود خواهد داشت. باید بدانید زمانی که به یک شبکه Wi-Fi متصل هستید، نباید طولانی مدت کار انجام دهید.

لازم به ذکر است در حال حاضر برای کسانی که جز پروژه Fi نیستند، باید از سیم کارت نانو سیم استفاده شود؛ البته در آینده تغییر خواهد کرد.

در آخر اینکه، در حال حاضر گوگل تکنولوژی ای سیم (eSIM) را در جدیدترین دستگاه های پیکسل شامل پروژه Fi راه اندازی می کند و منتظر همکاری با شرکای دیگر است.

امیدواریم مطالب فوق برایتان مفید واقع شده باشد.

لترپرس یکی از انواع روشهای چاپ است. همنطوری که میدانید ما روشهای مختلف چاپی داریم که تقسیم بندیهای برای ان ها از ابعاد مختلف وجود داره . یکی روشهای تقسیم بندی روش های چاپ روشی مییاشدکه در ان لوح چاپی رو مبنای تقسیم قرار می دهیم .

منظور  از لوح چاپی هر سطحی هست که ما با استفاده از روشهای خاص تصاویر و حروف مورد نظرمون رو برای چاپ باید ابتدا بر روی اون منتقل کنیم تا در مراحل بعدی با آغشته شدن اون به مرکب یا هر روش ماده دیگه ای غیر از مرکب امکان این باشد که تصاویر را از روی ان بر روی سطح چاپ شونده ای مثل کاغذ یا... منتقل کرد. 
لوح چاپ به عنوان یک سطح می تواند انواع و اشکال مختلفی داشته باشد اما وقتی صحبت از چاپ است شکلی که تصاویر ما بر روی اون نقش بسته اهمیت پیدا می کند و مبنای ما برای تقسیم بندی روش های چاپ قرار میگیرد:
1. روش برجسته
2. روش گود 
3 . روش غربالی (یا اسکرین )
4 . روش مسطح ( یا لیتوگرافی)
این روش ها  4 روش ایجاد تصاویر بر روی لوحها و به تبع اون 4 روش برای چاپ تصاویر هستند (‌ البته نه همه روشها بلکه روش های اصلی)

اما در مورد لترپرس 

روش لتر پرس یک روش چاپ برجسته میباشد که در ان تصاویر پس از برخورد مرکب با سطح برجسته لوح از روی اون بر روی مثلا کاغذ منتقل می شوند.

روش لترپرس یکی از روشهای اولیه و اساسی چاپ بوده روشی که گوتنبرگ پدر صنعت چاپ اونرو به عنوان یکی از اصلی ترین روش های چاپ ابداع و مطرح کرد. اما اصطلاح لترپرس در  دیده اولیه شاید اشاره به برجسته بودنه این روش نباشد چون معنی کلمه  « چاپ حروف » میباشد  دلیل این نامگذاری بیشتر تاریخی هست و به طور خلاصه علتش این است که روش لترپرس یکی از روشهایی بوده که ابتد از اون برای چاپ حروف چاپی استفاده می کردند و در اون مقطع روشی که برای چاپ تصاویر به کار می رفته عموما جدایه از روش چاپ حروف بوده. 
پس اساسا از لترپرس برای چاپ حروف استفاده می شده . قدیمی ترین روش کار هم برای آماده کردن لوح چاپ استفاده از روش حروف چینی حروف چاپی سربی در کنار هم و استفاده از اون برای چاپ بوده. که به مرور بظهور انقلاب صنعتی ، اختراع عکاسی و روش های نوین جای خودش رو به روش های دیگه حروف چینی داد. این یک توضیح مختصری از روش لترپرس بود. اما اجازه بده ببینیم که این روش و کاربرد اون امروزه چه طوری هست:
باید گفت که روش لترپرس و استفاده از اون امروز با به وجود اومدن روش هایی مثل چاپ افست و دیگر روش های چاپی از اون حالت یک روش عمومی و خیلی رایجش بیرون اومده. پس می شه گفت حروف چینی سربی هم به اون معنای عامش دیگه منسوخ شده.

اون چیزی که در ایران و از روش لترپرس باقی مونده یک روش اختصاصی برای انجام دادن یک سری کارهای خاص هست. عمده دستگاه هایی که از این روش هنوز هم می شه اسم اونرو شنید و ازش استفاده کرد دستگاه ملخی هست که به خاطره شکل کاره این دستگاه و شباهت ظاهر اون به پای ملخ در ایران به این اسم معروف شده.( البته یک نوع دستگاه دیگه هم برای این روش وجود داره که به اون دستگاه مسطح می گن) 
اما کارهایی که می شود امروزه با لترپرس انجام داد بیشتر به سمت قالب زنی متمایل هست. در این حالت از روش لتر پرس برای انواع کارهای پرفراژ زنی و ایجاد خط تا و یا قالب زنی و برجسته کاری استفاده می شود که همگی در اندازه عموما محدود و مشخص دستگاه به عنوان یک روش تکمیلی بعد از چاپ به کار می روند. شما با استفاده از روش لترپرس می توانید برای کارهایی که احتیاج به خط تا دارن یا احتیاج هست که یه حالت برجسته کاری روی انها ایجاد شود با استفاده از کلیشه هایی که ساخته می شود یا فرمی که بااستفاده از ابزار حروف چینی سربی در چاپخانه ساخته می شود استفاده کنید. همینطور می تونی از اون به عنوان یک دستگاه دایکات و قالب زنی ( خصوصا از نوع مسطح این دستگاه ) برای ساخت مثلا جعبه یا کلا قالب زنی استفاده کنید.

یکی دیگر از استفاده های این دستگاه کاربرد اون در شماره زنی سریال بر روی ورقهای چاپی هست که با اضافه کردن یک قطعه خاص به دستگاه امکان پذیرمیباشد. البته همونطور که گفتیم دیگه کمتر برای چاپ به اون عنوان استفاده از مرکب از این دستگاه استفاده می شود ولی هنوز هم میشه جاهایی رو پیدا کرد که با استفاده از این روش کارت تبریک و دعوت چاپ می کنند.

اما به هر حال استفاده از این روش و تحت نام لترپرس بستگی به کاربرد خاصی دارد که شما باید در نظر بگیرید و می شود ابتکارات جالبی هم با توجه به خصوصیت این روش برای اون در نظر گرفت.

بر اساس گزارشی جدید، گوگل در حال کار روی برنامه‌ی گواهی Made for Google است که سازندگان از آن برای ساخت لوازم جانبی گوگل استفاده خواهند داشت.

احتمال می رود که برنامه‌ی گوگل مشابه گواهی MFi (ساخته‌شده برای اپل) باشد. اپل تولیدکنندگان را از لحاظ اسناد و اطلاعات دقیق سخت‌افزاری، ابزار و پشتیبانی فنی تأمین می‌کند. در نتیجه تولیدکننده‌ها می‌توانند از لوگوی گواهی اپل برای تبلیغ محصولاتشان استفاده کنند. به احتمال زیاد گوگل نیز قصد دارد پشتیبانی مشابهی به شرکایش عرضه کند.

منابع مختلفی امروز ارائه‌ی گواهی Made for google (ساخته‌شده برای گوگل) توسط شرکت گوگل را گزارش کردند. اگر واقعا چنین خبری صحت داشته باشد، اواخر همین هفته جزئیات آن به‌صورت رسمی منتشر خواهد شد؛ چرا که گوگل در تاریخ چهارم اکتبر و طی رویدادی قرار است از گوشی‌های پیکسل ۲ و پیکسل ۲ ایکس‌ال رونمایی کند.

اگر این برنامه در رونمایی گوگل از محصولات جدیدش معرفی شود، به این معنی خواهد بود که در همان مراسم شاهد معرفی لوازم جانبی دارای گواهی Made for google خواهیم بود. این لوازم جانبی احتمالا شامل باتری‌، شارژر، قاب‌، داک‌ شارژ و... خواهند بود.

تاکنون گوگل این موضوع را تأیید نکرده است؛ بنابراین هیچ‌چیز قطعی نیست. برای کسب اطلاعات بیشتر باید تا اواخر این هفته صبر کنیم.امیدواریم مطالب فوق برایتان مفید واقع شده باشد

لیزر پرینترهای لیزری

نقش سیستم لیزر چاپگر در ایجاد خروجی مورد نظر بسیار حائز اهمیت است . در چاپگرهای لیزری قدیمی ، سیستم فوق از عناصر زیر تشکیل شده بود :

• یک لیزر

• یک آیینه قابل حرکت

• یک لنز

لیزر داده های مربوط به صفحه را دریافت ( نقاط ) و بر اساس اطلاعات فوق متن و تصویر مورد نظر را ایجاد می کرد. در هر زمان(لحظه) یک خط افقی چاپ می گردید. همزمان با حرکت پرتو های نور بر روی استوانه ، لیزر یک پالس نوری برای هر یک از نقاط مورد نظر جهت چاپ را منعکس می نمود. برای فضا های خالی پالسی تولید نمی گردید. لیزر نقشی در حرکت پرتو های نور نداشته و باعث تابش نور از طریق یک آیینه قابل حرکت است. همزمان با حرکت آیینه ، توسط مجموعه ای از لنزها ، نور تابانده می گردید.با تنظیم فاصله بین آیینه و نقاط در زمان تابش نور ، از به هم ریختگی تصویر پیشگیری بعمل می آمد.

دستگاه لیزری صرفا" در جهت افقی حرکت می کرد.پس از پیمایش افقی ، چاپگر، استوانه مربوطه را حرکت داده تا زمینه ایجاد خط بعدی توسط دستگاه لیزر فراهم گردد.

برخی از چاپگرهای لیزری از مجموعه ای از دیود نوری (LED) برای نوشتن محتویات صفحه استفاده می نمایند. هر یک از نقاط دارای نور اختصاصی خود خواهد بود. چاپگرهای با تکنولوژی فوق نسبت به چاپگرهائی که از دستگاه لیزری استفاده می نمایند ، دارای قیمت ارزان تری می باشند.

01		Accessory error. An error has occurred in the DIMM slot. The Attention light, Ready light, and Go light are blinking. The printer stops printing, and pressing any button has no effect.	1. Turn the printer off. CAUTION Inserting or removing DIMMs while power is supplied to the printer can damage the DIMMs. 2. Remove the DIMM and reinstall it to make sure that it is correctly installed. 3. Make sure that you are using a supported DIMM. See Accessories. 4. Move the DIMM to a different DIMM slot. If the DIMM works in a different slot, then DIMM slot 1 is malfunctioning. 5. To continue printing, remove the DIMM from DIMM slot 1.
