I have install a HP Laserjet 1020 & 1015 printers that connects to USB under windows vista ultimate. (Sp1). In our printed output we need graphics to be printed in 300 dpi. but only two options (600 dpi & 1200 dpi.) are available. I had solved this issue earlier in windows xp by using a different driver can't remember which (HP 4, 4L, 6 or 6L). Tried using all these in VISTA with no results.
If you have any idea about any different drivers (vista) for these printers which can print in 300 x 300 dpi. please help.
Thank you in advance.
