Why are printers that perform duplex printing set by default to only print single sided?
After much debate, it was decided by several support groups that it is best to use the default of single sided as our standard. By default, when you create a print queue, even if it is defined as duplex, the standard Microsoft installation software will default to single sided. When selecting double sided print outs, you have the choice of flipping printing on either the ‘Long Edge’ or ‘Short Edge’. Each individual user may have a different preference. In the near future, we are also planning on accommodating our UNIX customers that use LPR. In many cases, LPR users can not specify to print single or duplex. For Unix LPR customers, we have to create different print queues. To be consistent with UNIX Printer Server FNPRT, we are making the default queue single sided. For Windows users, once you define a queue connection, you can change the default setting to be duplex, and then all print requests you make will be performed in duplex mode.
