Since a 11 inch page has 3000 lines at 300 DPI the resulting memory requirements are 990000 bytes. Now of the 512K available in the LaserJet IIP some is used up for variables, buffers, etc. Also a full page of graphics really seldom means 11 inches. So you need at least 512K more but to be safe 1024K more memory in your LaserJet IIP to print a page of 300 DPI graphics. When comparing LaserJet IIP to the DeskWriter (for Mac) and DeskJet+ (for, dare I say it, MS-DOS) you must remember the Desk_____ printers need no extra memory or options to do a page of 300 DPI graphics. Also remember when printing a page of 300 DPI graphics the HP laser printers are not necessarily faster than the DeskWriter and DeskJet+ printers. The laser printer speed edge really comes out when printing text only or PostScript -- not bitmaps. Also note that the base LaserJet IIP has only a 50 sheet input tray -- a 200 sheet tray is a $200 option. The Desk___ printers have a 100 sheet tray but have no optional larger tray. The PostScript cartridge for the IIP has been anounced at a price of $995 and requires 2.5 to 4.5 megabytes of total memory in the IIP (in other words, 2 to 4 megabytes of optional memory).
