Question : I want to share a picture of the screen on my car’s display to explain something over Whatsapp. I know I could just take a photo, but is it possible to make a screenshot like on a Mac or iPhone ?
Answer : Yes, it is possible to make a screenshot of your car’s CarPlay screen. In fact, it’s as simple as making a screenshot of your iPhone screen : – first, connect your iPhone to your car’s navigation display (usually by connecting a USB-cable) – then, wait for the CarPlay screen to appear on your car’s navigation display – then use the CarPlay to get to the screen you would like a screenshot of – then, take your iPhone, and make sure it’s unlocked – now make a screenshot of your iPhone screen by pressing the ON/OFF and Volume UP buttons at the same time – then save the screenshot by either doing nothing (or by clicking on the small preview to enlarge it and clicking “Done” and “Save to Photos”) – then, open the Photos.app on your iPhone and there you’ll find not only the screenshot of your iPhone screen but also a screenshot of your car’s CarPlay screen saved as a photo that you can share (or edit) just like any regular photo
Question : I have a HP LaserJet M254dw that works great, but when I was trying to print a PDF yesterday, it took an enormous time to print and finally only printed the first page was printed, and the second wasn’t… There was no error message on my Mac or on the small printer display, so I tried again, this time only printing the second page. Since it was a page filled with lots of graphics and colours, I wasn’t surprised that it took a long time to print, so I left the printer to do it’s job for a while… when I returned after an hour or so, there was nothing printed and there where no error messages… So I tried again, this time I reduced the PDF to only the one page I wanted to print, made sure I would hear the printer startup (as it always does after receiving a new printing job) and I waited next to the printer to see wat happened… This time it also took a long time and nothing was printed, but before the display on the printer went black, I noticed a “low memory” warning being displayed….
What can I do to resolve this ?
Answer : HP has an explanation page on this “low memory” type of problem on it’s website, but if you don’t have any extra fonts installed, the first step I would recommend is installing new firmware if there is any. Here’s how to do that : – unplug the printer form power (to reset it – not strictly needed, but just to be sure) – plug the power back into the printer – download the latest firmware form the HP website by going to this webpage – then, find & open the “Software & Drivers” chapter – then, find & open the “Printer” chapter – then, typ “m254dw” in the search field – click on “HP Color LaserJet M254dw” when presented – then, find & open the link to “Firmware” – when the latest firmware version is displayed, click the “Download” button if you are sure you haven’t upgraded the firmware on your printer since the date it was released ( e.g. the current version number 20230822 means it is the firmware version created on 22nd of August 2023, but you can also check the official release date that is also listed ) – then, on your Mac, open the firmware installer you’ve just downloaded and follow the on screen instructions guiding you through the installation – when the firmware upgrade is done, try to print the PDF page again – if it is printed okay now : great ! …if not, try printing some other, page that has a simple layout, first – if that doesn’t work, check your printer as something simple might be wrong like an open tray or a loose cable (aside from the very small chance that your printer is actually broken) – if you are able to print something else, just try printing the problematic page again and make sure you check “Scale” (and not “Scale to Fit”) and set it to “100” in the “Preview” chapter of the Printing options before printing – then wait… – if that works (note that you might have to wait 10 minutes or so), you’re okay ! – if your page original was too large, and it has now been printed across multiple pages, try printing again, now with “Scale to Fit” checked – if “Scale to Fit” turns out to cause problems, open the PDF in Preview.app and (re)save a new version as JPEG or PNG (choose “Export” from the “File”-menu to get these options) that you can print
