When Microsoft dumped Windows 10 on me without asking it made my venerable Laser Printer 2300 unviable which made me very cross. I put it in the spare room for months.
In the mean time I bought another HP product an Office Pro 8620 in colour. This time an inkjet.
Two weeks ago fired up the Laser 2300 (6000 copies per refill B&W lo and behold a new software popped in Eureka moment.
Two weeks ago the colour ink ran low on the Inkjet all four cartridges. Solution HP inks at 180 dollars same size set. On line for 28 dollars including delivery 4 new double capacity cartidges. Attempt to run message non standard cartridges cartidges....no go faulty cartidge. So I rang HP questioned the company had a right to isolate and refuse after market, kept going right up to the top man immediately received a new program the printer works perfectly.
The 2300 weighs quite a bit so I understand your back problem and yes mate over 50 yrs of minor to major probs tells me it is so debilitating. Laminectomy of the whole lower 5 done.
Get well soon Derek mate seek help moving things I often do it pays.
Kind regards Peter.
