Re: No drivers.
Funny you should mention...
My company-issued laptop runs Win10. With the work-at-home being normal now, I took the time to equip my Fortress of Solitude (basement office) with a decent (i.e.: free and robust) laser printer, to wit: a very clean used Laserjet 5M*. Bought a JetDirect card for it ($20 on eBay) and put it on my home network.
The company laptop installed it as the default printer and all was well.
Fast forward a couple of weeks. IT discovered my laptop needed updates. Duly installed, and I spent a day getting things back the way I like them (and deleting XBox stuff, etc -- why this is installed on an "industry Pro" version of Windows, I don't know) and noticed the printer was missing.
After a little investigation, I find that sometime between the last update my PC had and the most recent one, HP removed the PCL5 driver from Win10. Now...why would they do that? Go to HP website...older version of the PCL driver is not to be found. And PCL6 is not downward compatible with PCL5 (at least as far as the LJ5 is concerned).
Could HP be trying to get me to buy a new printer? One, perhaps, with the ability to "expire" toner cartridges whenever HP's cash flow takes a dip? You might certainly think that, I couldn't possibly comment.
Luckily, The Internet came to the rescue. Some nice chap has archived the old HP PCL5 drivers for Win10. They install quite easily and...my printer is working again. Except every print job now pops up a little warning telling me: "black toner almost empty". Goodness me, and I just installed a new cartridge and have printed maybe three pages off it.
So HP has chosen not to offer driver support for "older" printers. I'm sure this was a huge burden for them, and I find their actions quite reasonable...NOT!
*The LJ5M is built like a tank, metal chassis, easily repairable and the necessary parts are inexpensive and readily available, since the LJ5 was sold by the millions and is still doing service as the default office printer, even in my company's offices. Mine was offered free and broken by a local law office. $150 worth of parts (a rebuilt fuser assy for $125 and a $25 gear) and it's like new. Repair instructions, of course, on YouTube.
