Our laserjet 5si printer is 20 years old, but the boss loves it. Over 500,000 pages have been printed and it still works very well and print cartridges are practically free.,
I have set up our SamsComputer which is new Dell Inspiron windows 10 pro desktop.
I cannot connect it to the 5si printer because this computer's windows 10 does not have a printer driver for any model of laserjet 5. Refreshing the driver list with the printer update button added a dozen printers, but still no Laserjet 5 entries.
Strangely, about 5 months ago I installed JanesComputer which is a different model Inspiron desktop, and had absolutely no trouble connecting to that same printer. (It continues to work just fine.)
The HP website's most recent download is from 2002, and does not work.
If found several potential drivers at other websites, but I am reluctant to use non HP sources.
I am getting desperate, so I tried copying the repository driver from JanesComputer to SamsComputer c:\BobsTemp\prnhp001.inf. I use "have disk" and pointed it to the .inf file. That showed laserjet 5/5m, which I selected. The install then failed with an file not found message, but it did not name the fmissing file.
