My HP LaserJet 4700dtn Printer is really slow, it taking 25 mins to do a 15mb pdf file. I am connected to the printer via a USB cable. How can i speed it up.? it has 256mb memory.

see HP LaserJet Pro Printers Memory is Low message displayed on the control...

HP LaserJet Pro Printers - 'Memory is Low' message displayed on the control panel HP LaserJet Pro - Troubleshoot 20.xx (memory failure) and 21.xx (print failure) error messages (ID: emr_na-c05049204)
HP Customer Support page and ensure the printer is running the latest available firmware. Print a Configuration Report from the control panel of the printer to check the installed firmware version.

If the printer supports expandable memory, you can install additional memory in the form of a DIMM. Check the printer's User Guide to see if it supports additional memory.

Break complex print jobs into smaller jobs that contain fewer pages.

If the printer is an MFP, delete stored faxes to increase available memory. Go to this document for instructions: HP LaserJet Pro MFP - Delete faxes from memory (ID: emr_na-c03264743)

Power cycle the printer to delete stored fonts or macros. It is possible to download fonts or macros in a way that power cycling the printer will not delete them; see Appendix A - Memory Allocation.

Changing some software and/or print driver settings might result in a less complex print job.

Use a different print driver. For example, a PostScript print driver will typically result in a more complex print file. If possible, try sending the file with a PCL6 or UPD printer driver.

Adobe PDF files can sometimes be very complex. Go to this document if printing PDF files is slow or resulting in memory out messages: HP LaserJet - Print job is slow or hangs in the print queue when printing Adobe PDF files (ID: emr_na-c04071740)

If the printer is connected via a network, try sending the file connected by USB cable only. This will eliminate possible network issues that are taking printer memory.

Appendix A
Memory Allocation Utilities or jobs that you download to the product sometimes include resources (for example, fonts, macros, or patterns). Resources that are internally marked as permanent remain in the product memory until you turn the product off.
Use the following guidelines if you use the page description language (PDL) ability to mark resources as permanent. For technical details, see an appropriate PDL reference for PCL or PS.

• Mark resources as permanent only when it is absolutely necessary that they remain in memory while the product is turned on.
• Send permanent resources to the product only at the beginning of a print job and not while the product is printing.

NOTE: Overusing permanent resources or downloading them while the product is printing might affect product performance or the ability to print complex pages.

I'm assuming that you're trying to scan to your computer.?? I'm not specifically knowledgeable about the HP M4345 printer.... but, it HAS to have a cable connection. The cable should be one that has a usb connection on one end, and a small kind of rectangular plug on the other that plugs into the back of the printer.. Look on the back of the printer. There has to be a connection, besides the jack for the 110 V.

Hi,your printer use 2 different USB and parallel interfaces..I recommend to use USB cable..
Pls visit the below links for these cables..
Just in case ,I have provided an URL for user manual as well.
Hope this helps! Take care and please Remember to rate/vote and give me

To use the printer with your computer, first you have to install the drivers and make power cable connection. HP LaserJet 1018 has USB connectivity. So, you have to connect it to the PC via USB Cable.

Visit the above links from HP Official Support and download the Drivers for your Model of the printer and Operating System (e.g. Windows XP) and user manual. Double-click the downloaded driver file and follow the on-screen instructions to install the printer.

Yes, there is an adapter. For example, see:

for such an item.

Hello,

On the back of the printer where the cable connects is actually a 36 pin connector, the end going to the computer is the 25pin end. What you will need to do is get a USB to parallel cable, they run $15-25, this will have the USB plug on one end and the 36pin centronix printer connection on the other end. This cable will allow your printer to be connected to the laptop. Office Depot and Staples should have the cable you need, if not you can do a google search for it and order one online.

I hope this helps, if so please rate our solution.

Follow the link and get the correct driver and get installed

Also try with another USB cable, If you are using a long cable, just try with a short one.

Need some additional info: -Network based or connected direct to the workstation? -How big are the pdf files? -Has anything changed with the printer, workstation/server host?
