CUPS+HPLIP Laser printer print one page at time in multiple copies or multi multiple pages documents

[Rollo Tommasi]

I need to print documents in multiple copies or docs with multiple pages using a HP LaserJet CP2025N laser printer and CUPS+HPLIP, but it seems that the printer get only one page at time, this means that all the times it finishes to print a page, it starts to wait the page after and in the meantime it puts its harware in "sleep mode", wasting 6-9 sec at page.

I get this issue only with CUPS+HPLIP driver; with Win NT6.0 + HP Universal Printing PS driver printer prints all the pages in the same session/jobs whitout any interruptions between a page ad another.

Watching the process with htop -d 0.2 -u lp confirm that ghostscript sessions elaborates one page at time during all printing session.

I use cups package of debian squeeze (latest stable) 1.4.4-7 and HPLIP ver. 3.11.5-1.1.

$ lpoptions -d laserjet

Someone have any idea to force HPLIP or CUPS to elaborate all the pages and send them to the printer in the same time? Thanks.
