/* I just got myself a brand new HP Desk Jet Plus printer to use with TeX. I and a number of other people asked the net for sources to one of the many DeskJet drivers which must be out there, but there was no response. I searched all the archives I could find, with similarly unsuccessful results. So I took the dvijet driver from the Beebe release and modified it for the desk jet plus. It might be called (as by some) a "vanilla" driver because it doesn't use downloadable fonts, but downloadable fonts requires an extra memory cartridge -- for that I would have just as soon bought the IIp. I did include some memory compaction, though, which reduces file size and transfer time by 50 - 70 % So it's not quite vanilla. The various compaction schemes can be switched off at compile time if the old Desk Jet doesn't support them (I have no idea) or if any of them prove buggy (possible). I include the modified source below, as I am guessing there are others out there on the net who would find it useful. Perhaps some kind soul will even archive it. It requires the rest of the Beebe driver code, which is commonly available -- eg, at ymir.claremont.edu & utah ... whatever. Hope this is helpful. Sorry if this isn't the place I'm supposed to post source, but it's the best way I know to reach people who might find this useful.

Each compaction * scheme can be switched on or off independently by defining any * or all of: * * XOFF -- X offset -- instead of a string of leading zeros, offset * by appropriate amount. Minimal savings when used with * COMPACTION mode set. * * YOFF -- Y offset -- compress multiple blank lines into a single * y skip command. * * COMPACTION -- Uses mode 2 compaction on Desk Jet Plus -- this is * the trickiest but most effective compression modification. * This is the likliest part to have a bug. * Lots of cleaning up can be done here. * * If you have an old Desk Jet (not a Plus) it may not have * all these abilities -- try undfining some of these switches. * * It should run straight with the Beebe driver set; you might * have to make some adjustments. * * Please let me know if you make any improvements or repairs. * Thanks * * Good Luck. */ #include "dvihead.h" /**********************************************************************/ /************************ Device Definitions ************************/ /**********************************************************************/ /* All output-device-specific definitions go here.
