Laserjet 4MP but same problem with 4L.
Windows 7, but same problem in xp.
2.8GHZ P4 desktop computer.

Printing text is acceptable.
But when printing graphics, it can take 5 minutes
to print a page. Use with a scanner to copy
documents is excruciatingly slow.
Printer has 18MB of ram.

The driver insists on sending 25MB of data,
according to the print monitor.
But the parallel port should be able to do
this in half a minute.
Doesn't seem to be any way to use less
than 600dpi resolution.

HP website doesn't even mention win7. Claims
that vista has all the driver you'll ever get.

Is there anything I can do with the driver
or configuration to make this go a LOT faster?
I rarely need 600dpi. 150dpi would work fine
for most of what I do...just can't find a place
to change it.

Thanks, mike

Hi!

Which absolutely does not come as a surprise. You're making a very tall
demand of this printer.

Specifically, the processor in the printer has to take the data coming in
from the parallel port and figure out (I believe "rasterize" is the correct
term) what to do to draw it on the drum and get it on the page.

This takes time, especially for graphics that are sent in bit-mapped form.

You can have all the RAM you want, and the printer won't go any faster. Its
processor only goes so fast, and more memory cannot make it go faster.

There may not be one.

Vista drivers ought to work fine on Windows 7 for the most part, especially
for something like a printer. (This statement excludes all host-based
printers, which your LaserJet 4MP is *not*.)

If you can't lower the quality of the output (and you probably can't go
below 300 dpi anyway), you may need a printer with a much faster processor
onboard.

This wiill depend upon the resolution you are scanning at. How are you
controlling this?

First, scan at a lower resolution. 200 DPI black and white, for a
start. Use the PCL driver for this.

Parallel speed depends on several things. Your parallel port may be
capable of 1M/sec, but that 17-year-old printer probably can't accept
input at that speed.

It's under Properties/Advanced/Printing Defaults/Advanced/Graphic/Print
Quality in the Vista driver. Double advanced!

Scanning at the same resolution as printing may be the fastest. Depends
on the the computer.

According to HP's website this printer can print at (as almost every
laser printer I've ever owned or worked with) numerous resolutions.

In the case of the 4MP those resolutions listed are: 75, 150, 3000 and
600 dpi.

Sounds like the driver you have is not offering the full capabilities.

According to the HP website with the standard internal memory (which I
believe is 1 meg) can print up to a full page of graphics at 300 dpi.
However, with MEt even higher resolution may be possible without added
memory with graphics, however, the performance may be downgraded.

I wonder if you have some bad or incompatable memory, of if it needs to
be removed and reinsterted due to bad connections.
