I have a customer which is running a old DOS PC using Parallel I/O with a down HP LJ 4L needs a DC Controller PCB which I cannot find. Can you use any type Printer in the series, such as 4ML, 4P or 4 MP...

In general, yes. Some model-specific features won't work with other models, of course. For example the 4P does PostScript while the 4 does not. But as long as the customer confines himself to basic printing, the 4L driver should work properly with any of the 4-series printers.

Hi this machine has a power supply unit... may have fuses you can change on it.... have you tried the fuse in the plug? powersupply unit avaialable on line, may be cheaper to replace the printer though.

What's the difference between a LaserJet 4L and 4ML?

M for macintosh
The 4ML is packed with features. Print on a wide variety of standard and custom paper sizes, envelopes, labels, transparencies—you name it!

Of course, the LaserJet 4L is the same printer, but without the built in Macintosh and mixed network capability.

I amm looking for a driver under windows98 for HP 4l

The driver for the HP 4L printer should be built into Windows 98. Goto add printer, select HP and look for your model. If you cant find the exact model try a laserjet model that is close, it should work fine.
Hope this helps

Laserjet 4L the lights are out not printing

If all the lights are out you need to make sure it is plugged into a good outlet and the power cord is good and plugged securely into the printer. If all this checks out you need a tech or a new printer.
